The best brownie mug cake

Single serving and easy to make, this decadent chocolate recipe can also be high protein, gluten free, sugar free, and vegan, with no eggs required.

And do you want to know the best part? Unlike many other chocolate brownie mug cake recipes, this one calls for absolutely no box brownie mix!

Feel free to add chocolate chips, or top with Coconut Ice Cream or Keto Ice Cream.

The gooey brownie in a mug was adapted from my healthy chocolate mug cake, which is one of the reader favorite recipes on my site.

To turn it into a single serving brownie, I played around with the ingredient ratios and also added some Dutch cocoa to give it that ultra rich, deep and chocolatey classic brownie flavor.

Brownie Mug Cake Ingredients

Brownie mug cake ingredients

For the cocoa powder: The recipe calls for both regular unsweetened cocoa powder or cacao powder and Dutch process cocoa powder. If you can only find regular cocoa, it still works without Dutch. The brownie mug cake will just not have as much of a rich traditional brownie flavor.

What type of flour? You can use white all purpose flour, whole grain spelt flour, or oat flour. There is also a keto option included in the recipe. I have not tried almond flour, coconut flour, or whole wheat flour here and therefore cannot recommend those.

For the fat: The video uses coconut oil, but you can substitute any neutral oil or your favorite healthy nut butter of choice, such as peanut butter or almond butter.

While I haven’t tried a low fat version, many readers have written in to say they’ve had good results replacing the oil for applesauce or mashed banana. So you can try one of these fat free ideas at your own risk.

For a protein mug brownie: Simply substitute the tablespoon of cocoa powder with an equal amount of your favorite chocolate protein powder.

Flavor variations: Add a few drops of pure peppermint extract for a mint chocolate brownie in a mug. Or add a drop or two of almond or maple extract or up to half a teaspoon of instant coffee powder.

You can even make a Nutella brownie mug cake by replacing the oil with a spoonful of chocolate hazelnut butter or this Homemade Nutella Recipe.

Brownie In A Mug Recipe

How to make the recipe

To whip up the chocolate dessert, simply stir together the cocoa powder, flour, sugar or sugar free sweetener, baking powder, salt, oil or nut butter, milk of choice, and pure vanilla extract in a in a coffee mug or heat safe dish.

The brownie can be made in a microwave or a conventional oven. Be sure to grease the mug first if you want to remove the cake before eating it.

If you are baking the mug brownie in an oven, preheat it to 350 degrees Fahrenheit. Once it reaches the set temperature, bake the mug cake dessert for fourteen minutes on the center rack of the oven, then let it cool.

Or if you prefer a microwave brownie, place the dish or coffee cup in your microwave and cook until done. Time will depend on your microwave’s wattage.

I cooked my fudgy mug brownie for a minute, followed by two ten-second increments, so the mug dessert will be ready in about eighty or ninety seconds total.

Store leftovers covered in the refrigerator for up to three days.

Wait, what leftovers?

This single serving brownie in a mug recipe is perfect for any time you’re craving an easy chocolate dessert.
Cook Time 5 minutes
Total Time 5 minutes
Yield 1 mug brownie
5 from 64 votes


  • 1 tbsp unsweetened cocoa powder
  • 2 tsp Dutch cocoa or additional regular
  • 3 tbsp spelt, white, or oat flour (Here’s a Keto Mug Cake Recipe)
  • 2 tbsp sugar, or sub erythritol if desired
  • scant 1/4 tsp baking powder
  • 1/8 tsp salt
  • 1 tbsp oil or nut butter (some readers sub applesauce or banana)
  • 3 tbsp milk of choice
  • 1/2 tsp pure vanilla extract


  • Notes: If you want to remove the brownie mug cake before eating it, be sure to grease the mug before starting. If you can’t find Dutch cocoa, subbing additional regular will still work; it will just have less of a brownie flavor. I haven’t tried subbing applesauce or banana for the fat and therefore can’t vouch for the taste of that substitution.
    If baking, preheat oven to 350 F. Combine all ingredients in a mug or 1-cup dish (or two 1/2-cup dishes). Either bake around 14 minutes, OR microwave until set. Microwave times will vary depending on wattage and if using one or two dishes – I cooked mine for 1 minute, followed by two 10-second increments.

  1. Linda Reid says

    Katie your recipes are amazing. Thank you so much for sharing them with me. I just made the mug brownie and it is so yummy. I’ve made a lot of your desserts and regular dishes and we have enjoyed them all!!

  2. Catherine says

    Hmmmmm… This is NOT a ready in five minutes dish. Measuring out the ingredients takes a lot of time. Will not be trying again. Was not worth the effort.
    Also, the tiny text in this comment box makes it difficult to read what I’m writing.

    • Hannah says

      It really shouldn’t take longer than a few minutes to measure out these ingredients. I would guess 2 or 3, although I have not timed it. But you could also measure the dry ingredients into bags to have on hand, that way you only have to get out those ingredients once. Hope that’s helpful.

      • Ariel says

        Just made it took me 5 minutes to get the ingredients together and 1 minute to cook so not bad lol. That’s a great idea Hannah thank you! I did however use 2 tbsp cocoa powder and 2 tbsp sugar for my bf. He thought the original tasted “sugar free?” That may help some. Thank you for this recipe!

        • Ariel says

          Just made it took me 5 minutes to get the ingredients together and 1 minute to cook so not bad lol. That’s a great idea Hannah thank you! I did however use 2 tbsp cocoa powder and 3 tbsp sugar for my bf. He thought the original tasted “sugar free?” That may help some. Thank you for this recipe!

      • CastleDark says

        5 stars
        that was indeed a very helpful comment!
        i have some tweeny cute lil mason jars that i was wondering what to do with…
        & thanks to u, im now gonna prep these ingredients in them & store in pantry as my ready to go mug-cake, dry cake-mixes!
        so THANKYOU!

    • Anya says

      I agree, this recipe looks like it would take closer to 15 to 20min by the time you measure everything out, bake it, and then clean up all spoons that get dirtied from measuring everything!

      • Jason Sanford says

        If you bake it in the oven, it will be longer. But the microwave version can be done in about 5 minutes, including cooking time.

        • Anya says

          Even if I used a microwave, this recipe from start to finish would take me 15-20min. I just wanted to agree with the original commenter and let her know that I felt the same way.

          • Jason Sanford says

            I would time it. There’s no way it should take that long to measure out a few ingredients! But the bag trick would definitely help to cut back on time regardless.

          • Anya says

            I don’t understand why you want to dispute my personal time estimate. All I wanted to do was interact and connect with another commenter.

          • Michelle Johnson says

            No way does this take 15 minutes on the microwave version. This barely took me five minutes from start to finish eating. I’d add chocolate chips for a deeper level of chocolate. Loved this recipe!

        • Kat says

          5 stars
          Any way you slice it this is still a really quick recipe! I’ve been making it for years and it was a real lifesaver for my college days living by myself. I still make it often when I have a craving because it’s made with only pantry staples and saves me eating a whole pan by myself!

  3. Holly says

    I have made this recipe more times than I’d like to admit since you posted it on instagram. I love using oat flour and it does come together in 5 minutes or less especially with practice ? It’s my favorite mug cake!

    • Jason Sanford says

      Most grocery stores or target or walmart will have it. Just look for the words “processed with alkali” somewhere in the ingredients. Hershey’s Special Dark is one brand in major stores, or this is the one Katie often uses:

  4. Linda Griffin says

    Just made this and it was delicious. I used almond butter and Hershey’s Special Dark chocolate. It’s great to be able to make just one! Keeps me from eating too many ?

  5. Osnat Ravid- Amir says

    I Love your recipes and your beautiful pictures!
    Just got your Mug Brownie recipe and it looks amazing.
    I think there is a mistake in the nutrition facts though, the amount of sugars that is written is 1.1 which doesn’t make sense given the 2 Tbs of sugar. Maybe its for the erythritol version?
    Thanks for all your wonderful recipes, keep going!
    Osnat 🙂

  6. jermaine gray says

    Hi, kate your content is lovely so far I’ve looked at a few of your recipes and the vegetarian brownie looks good, and i am all about my health so kudos to you again.I will be trying out the vegetarian brownie.

  7. Becky says

    I love it. I know I will be making it quite often. The best part is that was able to enjoy a delicious treat and I don’t have a whole pan tempting me.

  8. calgal says

    This is so, so delicious. I subbed the oil for applesauce and baked in the oven, which tasted much better than the microwave version (I tried both). It definitely needs a frosting of some sort, IMO. This is in my favorites folder and I’ve made it at least 5 times already!

  9. Eleanor says

    Made this by splitting the batter between two ramekins and baked them in the oven. I added mini chocolate chips, used coconut palm sugar, and peanut oil and they were perfect with vanilla bean ice cream on top!!! Will absolutely be making these again and again!!!

    • Karen Terhark says

      vanilla bean ice-cream is EXACTLY what I wanted to go on mine but had to settle for vanilla chocolate chip. Vanilla bean would have been the bomb!!!

  10. Susan says

    I tried this today for the first time. It was delicious and took me just under 10 minutes but only because my hubby reorganized the pantry and I had some scavenging to do to find all the ingredients. Next time will be less than 5 minutes for sure!

  11. Karen Terhark says

    I made the Brownie-in- the- Mug and granted I didn’t time it but good grief, does it really matter? I think I had mine put together between 5-10 minutes start to finish. ha ha, that is subtracting the time I spent keeping track of a hyperactive puppy. Now to rate the recipe. 5 stars!!! It was so delicious. It definitely satisfied my sweet tooth and dessert craving. I used dark chocolate cocoa powder, full amount, and white chocolate chips. I have to eat gluten-free so I used oat flour. I only needed 1 minute and 10 seconds to cook. I will try it with organic natural peanut butter next and coconut oil another time. Has anyone tried olive oil? This is nice to have a single serving of so you can’t over-indulge. I wish i had taken a picture after it was done and with a cute little scoop of ice-cream on top.
    Thank you Katie ~ I have enjoyed looking at your recipes and have tried a few. I admire your creativity.

  12. Hallie says

    The chocolate cake in a mug has been my go-to for a last minute dessert since it was published. Lately I’ve been really into brownies so this adaptation is great! I always underbake mine in the microwave. I make it as written except for half coconut oil and half applesauce and a few chocolate chips.

  13. Sue says

    This recipe is amazing. Takes less than 5 minutes to assemble and 1 minute to microwave. And then a decadent brownie treat on a day I really needed a chocolate pick-me- up. Thanks Katie!

  14. Cola says

    This was the best mug brownie I’ve EVER had. It was so moist! I’ve been so skeptical of mug recipes cause many have failed me no matter how hard I tried. Thank you so much!!!!!

  15. MamaTree says

    Fabulous. Didn’t have patience for oven so made microwave version with regular cocoa, AP flour, brown sugar, sunflower oil, oat milk. I gilded the lily by shoving a tablespoon of chocolate chips into the center after the first 60 seconds (before the last 20 seconds). Sprinkled the top very lightly with flaky salt while I was waiting for it to cool enough not to burn my tongue. Thank you for this! xo

  16. anonymous says

    I subbed in almond flour and it made a wonderful lava cake like base which I then topped with chocolate chips. Would highly recommend!!! Thank you Katie!!!

  17. Luana Johnson says

    FYI…I timed myself. It took me slightly over four minutes to add the ingredients and one minute, ten seconds to cook in microwave and I had my kitchen cleaned up in the time it was cooking! Yay! So total t Maybe it’s because I love to cook and I do it a lot. By the way I used regular old good quality Cocoa and canola oil. While admittedly it wasn’t as good as a “normal” pan of my brownies, it was super quick and I was having a craving that this satisfied completely. I topped it with a heaping spoonful of cookies and cream ice cream and it was amazing…much better than ANY of the store bought brownie-for-one mixes. This brownie recipe is delicious and I will definitely make again! Thank you for the recipe!

  18. Liz says

    This looks like my go-to chocolate fix. Thank you Katie.
    Am I imagining things or was there a mention of a contest by the maker’s of the chocolate chips you used in the recipe? If you wrote something in the comment box that they liked, then they would provide you with a year’s worth of chocolate. Did I read this somewhere else?

  19. Kristen says

    So thankful for your recipes Katie! My son and I love them. He has an egg allergy and your recipes have allowed him to stills enjoy delicious treats 🙂

  20. Abieda Roberts says

    Everything i have on your blog has turned out so good!!! But this has been our favourite! Have made it so many times for friends and family. Everyone loves it. Thank you so much.

  21. Mary says

    I just made this – it was quick and delicious. Measuring was quick and easy – did 1 minute plus 10 seconds – great recipe!

  22. Karen says

    I made this used part gf flour, added a few drops of olive oil and some mashed banana turned out really well. But if you didn’t want chocolate/banana flavor I would do the applesauce next time. I topped it with carmel and chocolate sauce. Delicious!

  23. Sindy says

    Had to laugh at the person complaining about the time – my first thought was, damn girl you gotta big kitchen! Took about 5 min start to finish and only dirtied 1 TBL and the mug. Used reg flour, reg cocoa, canola, almond milk, added in a few nuts and a few vegan choc chips. Microwaved for 1 min 30 sec – Surprisingly the texture was really good, more cake like than brownie, but very good. It’s actually fairly rich, so I topped it with almond milk ice cream and only ate half, saved half for later. The TBL of oil is a lot of calories, so going to try either banana or even flax seed/water next time. All in all, a great recipe to satisfy the craving. Thanks!

  24. Margaret says

    Just made the chocolate brownie mug cake exactly as recommended.. 1 min in microwave the 2/10 second hits. Came out perfect..I did sprinkle chocolate morsels on top before cooking.

  25. Jacqui says

    Could you use coconut flour? If so, would it still be 3 tbsp? If you were substituting the applesauce for the oil, would it be the same measurements? Thanks!

  26. Megan says

    I wanted dessert. My husband wanted to watch The Walking Dead. So I had to get out of the downstairs pretty quick-like (I can’t stand the noises the zombies make). Moments, mere moments, after I found this recipe, I was happily upstairs enjoying it. Moments, mere moments, later it was gone! Delicious texture. Great flavor. All the good things.

  27. Janet Arnold says

    I shared this recipe (and a mug-full of cake) with my retired-home-ec-teacher mom. She said it reminded her of s “steamed pudding”. We have made several versions with lots of variations and they all turn out great.

  28. Yvette says

    I was craving it late last night. Woke up this morning and decided to make it:) went well hella way better with ice cream:) can’t wait to make it for my husband!!!
    Super easy!!! Instead of oil I just put butter.
    Thank you!!!

  29. Sarah says

    SOOO good! I just had a brownie craving I couldn’t satisfy and this was perfect! I tried it with applesauce – even used part of a Go-Squeeze packet from kids! – and microwaved 1 minute. Then did another 15 seconds and it was set. I put a few mini-chips on top and it’s fantastic! Definitely will make this one again!

  30. Braydon says

    Poured a bit much milk but it just added its own choclate sauce now im gonna eat it ty for the recipe even though im a kid im very intrested in cooking.

  31. Dube Veena says

    I doubled the recipe, wanted to make little more than the small batch.
    I baked in the conventional oven at 350.
    Do I double the baking time from 14 minutes?

  32. VegiMom says

    This was great! Gluten free and eggless and ready in about 5 minutes! Perfect fix when you are craving a chocolatey snack!

  33. shazza says

    Just made this, and it was moist and delicious. Added less sugar, but served with a dollop of vanilla ice cream. Best Mug cake ever. Yum

  34. Kelly says

    I made this twice. Once as listed, used coconut oil and added some chocolate chips. Cooked for 1 minute. It was good but felt more cake like than brownie. The second time, I added an additional tbs of sugar, used butter, and added both choc chips and peanut butter chips, cooked one minute…this turned out more brownie like and gooier. Delicious either way!

  35. Lachef says

    Very good. Doubled the recipe and buttered two ramekins cooked it for about 1:30 each in microwave. Delicious (oh and used apple sauce instead of oil). Great texture intense brownie taste. 😊

  36. Stef says

    Made it with applesauce and it turned out perfectly, topped it with some peanut butter while it was still hot so it melted! Also added in some chocolate chips for a little extra chocolate!

  37. Holly says

    I used all purpose flour, measured everything carefully. It was moist but cooked at a minute and a half. Like another reader, I think it was a bit cake-like. I might try taking the baking powder down a little next time. So glad you shared this! I’m sending a link to my friend.

  38. Karina says

    Straight-up delicious. I used a combination of oat and white flours. This is a super awesome recipe if you want a warm, chocolaty dessert but don’t have the time/energy to bake. I have made this many times and will make it again.

  39. Esti says

    Subbed peanut butter for the oil. Not quite a “brownie” but definitely satisfied my sweet tooth. I didn’t have ice cream, but that would have made it much better!

  40. NicaD says

    I made this tonight with coconut oil, monk sweetener, vegan chocolate chips, and almond milk. It was so so good! Microwaved for 1 min, then another two 10 second increments as suggested in the recipe. Just like you said, and voila. Perfect. So easy and delicious, great to curb the chocolate craving while sitting on the couch watching TV. Dangerous…

  41. Debbie says

    I’ve made this brownie in a mug several times now. It always tastes great and is so quick and easy. Mine seems to bake more like cake than a brownie, but I still love it. Thanks

  42. Rosita Thibodeaux says

    5 stars
    At 65 years old I’m still a major chocoholic at times! Your recipes are AMAZING Katie! Thank You so much for making this old woman’s day as usual! You never fail!

  43. Dan says

    I’d never made a brownie in a mug before so I was a bit skeptical, but this is amazing. Using date sugar, whole spelt flour and almond butter makes this a nutritious dessert (until I added the vegan vanilla ice cream). I love that I don’t have an entire pan of brownies to tempt me and I can make a single serving whenever I want. This recipe and concept has changed my life for the better. 😀

  44. Tess says

    I loved this brownie in a mug. I added chocolate chips to mine. It came out perfectly!
    For those who were crabbing about it taking too long to put the ingredients together, do us all a favor and go out for dessert.

  45. ava b says

    tastes so good! i added about a table spoon of egg and dark chocolate chips and cocoa powder! and took a little over a minute in the microwave! definitely recommend and will be making again!

  46. MrsT says

    Delicious! I made mine with coconut milk, applesauce, AP flour and only 1/2 the sugar BUT then I sprinkled some white chocolate chips and broken up Oreos in it 🤤 incredible!!

  47. A says

    okay, so I made this and it’s fantastic. I mean what isn’t w/out sugar? My only gripe is it’s SO small, lol. Wishing it was a whole entire brownie serving lol

  48. AtwoodzNana says

    I had been trying brownie in a mug recipe into the night. Didn’t like them. This one is delightful, esp since I added a half package of Swiss Miss Hot Cocoa to it. I had run out of Cocoa powder. The baking powder seems to make it more cake like and light – less brownie like but so good.

  49. Katie says

    SO good! Tasted more like chocolate cake than a brownie, but super tasty—hit the spot! I used regular unsweetened cocoa and all natural almond butter. I also added chocolate chips and Heath bar chips. Yum!

  50. Marifran says

    OMG! I tried this after doing a search for chocolate mug cake. I love this recipe! It came together super quick and stood up to my substitutions and additions. I used oat flour. Cut sweetener a bit to 1 TBSP erithrytol and 1 tsp real sugar. Used unsweetened applesauce instead of oil. Subbed 1 tsp cocoa with 1 tsp peanut butter powder. Took a little longer in my micro, possibly due to extra liquid from applesauce. It came out amazing! I will make again for sure when craving something homemade, sweet, and a little healthy (?!?!?)!!! Thanks so much!

  51. Lauren says

    Katie, I put these ingredients together and decided not to bake it. I left out the baking powder, and instead, am enjoying it as edible brownie batter. I’ve refrigerated it, and it’s far better than any store bought edible brownie batter. I’m sure one could easily heat-treat the flour, but I didn’t do so. Anyway, I’ve done this a number of times with your other recipes, sometimes quartering cake recipes and enjoying the batter in an unbaked form. Maybe this makes me crazy, but I thought I’d let you know and say thank you for healthier edible cake and brownie batter recipes! –Lauren

  52. Claire Y. says

    First off, I will be making this again! I used apple sauce instead of oil and kept everything else the same plus added chocolate chips. My husband and I thoroughly enjoyed them! The only weird thing was that they took about 26 minutes to cook in the oven!!! I used smallish fiestaware mugs and placed them on a small baking sheet. I might try the microwave if I’m in a rush next time 😛 thanks for the delicious recipe!

  53. stef says

    absolutely brilliant, takes no time at all to measure out the ingredients in a cup using a tablespoon/teaspoon.

    great activity for kids, and if you need a last minute dessert!

    I cooked it in the microwave, a lovely soft moist brownie. just need some ice cream to go with it now!

  54. Larissa Stevenson says

    Oh my god, this is just amazing!! What I love about this recipe is that you can add anything to the brownie and it turns out perfect! One of my favorites is to add jam after filling halfway, top the brownie off, and then ice with peanut butter, like a chocolate PB&J sandwich!

    • Castledark says

      5 stars
      (Am on it!! making some jam right now!! outa froz strawberries, coconut sug & chia seeds in lil pot on stove top)

  55. Tamiko says

    I followed the recipe to a T, used AP flour, but it wasn’t great, very dense and shiny on top, not like the gorgeous crackled one you made in the photo. The taste was missing something for me, but that may just because it didn’t turn out right… Any ideas as to where it went wrong ? Everyone here raves about it, i want to try it again !

  56. Alex says

    When a recipe asks for dark cocoa, could cacao work? I tried it and it tasted really good on one of your mug recipes ! I’m left wondering though — what does dark cocoa taste like?

  57. Mrs. G says

    5 stars
    Brownies are my favorite dessert, but my husband doesn’t care for them—and we both need to be dieting. So being able to make just a serving at a time is wonderful! I mixed up two sets of dry ingredients just so it’s not so obnoxious to get everything out twice. Next time I will try Nutella instead of oil, and less salt: it came out salty for some reason. But rest assured, THERE WILL BE A NEXT TIME because this is GREAT!

  58. Milan Aron says

    4 stars
    I randomly stumbled across this recipe and I must say I’m impressed. I used oat flour and organic “wholesome” zero sugar. I was just missing the vanilla. I’m sure it would have tasted even better.

  59. Vicki Bynog says

    5 stars
    Recently had to change my diet to gf & df. What a dbl whammy. I happened across this recipe on Pinterest. I split this into 2 dishes as I’m also a member of WW and the 1 serving points was more than I cared to use.

  60. C Douncet says

    5 stars
    This was really. I subbed 1 tbsp almond flour for flour.
    I have tried others and not have good as this.
    Cooked 1.5 min.

  61. Naiad says

    5 stars
    This was so easy and delicious. I did add semi sweet chocolate chips. Took about 5 minutes to find and mix all ingredients. Cooking time was 1 minute plus 2 times at 10 seconds. Made some whipped cream flavored with maple syrup to go on top. Thank you!

  62. Joann says

    5 stars
    Just made your brownie mug recipe in
    Microwave & added a few chocolate chips & it was delicious & helped with my chocolate craving!😋

  63. Char says

    5 stars
    Fast and delicious! We love your blog, thanks so much. I doubled the recipe and cut the sugar by 3/4 and added chocolate chips. (Microwave for 1:15, which was maybe a tad undercooked) We don’t like things very sweet, so that was perfect with some ice cream!

    (took me 16 min from deciding I wanted to make this, looking up the recipe, getting ingredients and making, microwaving, cleaning up, getting my kids to clear their dinner plates in anticipation, and spooning out with ice cream. So definitely the perfect spontaneous treat!)

  64. Desi says

    5 stars
    Sooooo good. Great quick sweet treat for one when you want something for movie night. I used my own G/f flour blend and refined coconut oil and organic dark brown sugar. I topped with coconut whipped cream.
    This was very very very good. It is definitely a triple five star rating 🙂
    Thx Katie

    Why have I not tried this SOONER!!!!!
    So easy and so delicious! I threw it together and then microwaved for one minute. It was moist, dense and chocolatey.

    People complaining of it taking a long time must be slow bakers, must have a huge kitchen, or must just want something to complain about. I made it and from start to finish, it was 5 minutes. I used dark chocolate almond milk in mine, and drizzled it with melted peanut butter and it was AMAZING.

  67. Rena says

    5 stars
    Delicious I did make a mistake and added baking soda instead of powder so it turned out more cakey but that’s on my part

  68. Laura says

    5 stars
    OMG Yum. Made mine a little less sweet, and used about half the oil in the recipe and a little extra plant-based milk to keep the liquid volume the same. With less oil it’s more like a dense cake, still quite lovely. Wish I had some raspberries!

  69. Melinda says

    I’ll start by saying that I’ve tried a looooot of mug brownies. I’m currently going through a phase of trying them all haha. This one isn’t particularly my very favorite, but it IS going in the “make again” folder! It was a little more cakey than I prefer (vs. batter-y), but the flavors were still good! I used 1/2 monkfruit and 1/2 sugar. Oat flour. Avocado oil. Almond milk. 3 Tbsp regular cocoa.
    Thank you!

    Best Brownie Mug cake recipe I’ve ran across so far! I doubled the recipe and used self-rising flour and left out the salt. We enjoyed it.👍🏻

    Delicious. I used peanut butter and all regular cocoa powder. It turned out great. At first I thought it may have been a bit dry but it literally melted in my mouth.

    Quick fix for my chocolate craving! Quite yummy and will definitely make again. Took me altogether 4 mins, if that, to prepare and cook.

    it’s a good little base cake. i don’t think i would’ve liked it as much if i didn’t add mini choc chips and a scoop of ice cream because the cake itself was lacking a bit. if you’re just going to eat the cake, definitely add another tbs of sugar and that should help. good recipe! helped my craving 😛

    I mixed this up with ease and at the last minute mixed an egg and put 1 Tb in it. (I know: I shd mix as it is written THEN change it up). Great texture and flavor! Easy to make- I microwaved. Yum! I will make it again!

    Mine exploded in the microwave, but it was amazing. Best brownie I’ve ever eaten! I don’t feel stuffed at all either. So good!!!!!

    I just made the mug brownie and it’s so so good. I love it. Very easy and love that it’s gluten-free made with oat flour. Thank you for the recipe. I will be making it often 🥰

    I don’t know about the person who was complaining about how much time it took, but for a fudgy, yummy treat, it certainly doesn’t take that long if you do it in the microwave. I’ve made it twice so far when I was in the more for a chocolatey treat and it hit the spot. I will be making this a lot more for a quick delicious bite! Thanks for the recipe Katie!

    This is a filling brownie! I used all dutch cocoa and all-purpose flour. I honestly enjoyed eating the batter more than the brownie itself! The batter has a nice consistency with lots of sweetness. Once microwaved, the cocoa overpowered any sweetness in the brownie, and it left me dreaming about eating the batter again haha! Overall a nice moist cakey consistency in the brownie.

    Hi Katie,
    I recently started an elimination diet based on a food sensitivity test I took that indicates I have “leaky gut” and I am having the hardest time finding recipes that eliminate almost everything. I found this recipe and I have tried it several times. I finally found the right combination and it makes a fantastic alternative brownie to fill this girl’s sweet tooth thanks to your base! I used all the same ratios, but substituted cassava flour, coconut oil, coconut sugar, baker’s 100 cacao, and unsweetened coconut milk (added a tiny bit more milk because I also added a half scoop of my unflavored collagen protein). I wanted to let you know this combination makes a great brownie for alternative grain folks/vegans and thank you again for helping me get through this crazy diet!

    Just made this in the microwave and it was great! Super easy to make, added icecream and caramel sauce on top and it was delicious.

    One word review – DANGEROUS!
    I used 1 T. peanut butter that was very dense, so the batter needed 1 T. of unsweetened applesauce.
    80 seconds in microwave was perfect.

  82. Nicole says

    Great recipe! Perfect quick one for when the kids want something sweet for a little dessert. So decadent that the 2 share 1 serving. Win win. Thanks for sharing, much appreciated.

    This is awesome! Perfect consistency. I like to mix in semi sweet chocolate chips. I also substitute Swiss hot chocolate powder instead of Dutch. Although not very healthy, It turns out excellent everytime.

    I subbed applesauce for oil because they, why not?
    It yielded a more spongecake-like texture, and, surprisingly, made me not miss the dutch cocoa powder, as the (slight) acidic component of the apple brought out the darker flavor of the regular cocoa powder. All in all, I’d definitely make it again.

    Highly recommend this recipe! I got distracted and forgot to stir the ingredients together, but I stirred it all together after it was already mostly cooked and it was not beautiful but still delicious. It was a very generous serving, so I would maybe make it in two mugs next time or halve the recipe. I have never made a mug cake before and this was fun and tasted great. Thank you!

    It is a delicious and easy recipe that never fails to please. I added 1tbsp of no-sugar Peanut butter as a dollop to the mix just before baking and1 tbsp of Lily’s dark chocolate chips to the top after. The results are a lava PB center with melty dark chocolate topping – amazing! Thank you!

    I doubled this recipe and microwaved it in a bowl- it turned out great! I threw in a handful of dark chocolate chips too. Will definitely be making again!

    Oh my goodness. I’m an avid baker but this is the first time I’ve ever tried making a brownie in a mug. Are you kidding me?! This is hitting the spot like no other. i followed the recipe exactly with coconut oil and Hersheys special dark cocoa and it is delicious! I was skeptical, but this thing puffed up and came out looking perfect. Texture is more like a cake which I don’t mind at all. Definitely add chocolate chips! I sprinkled mine on top but wish I had mixed them throughout. They add such a great melty gooey texture. I’m not sure why anyone would say this serves two, as if you’re making a brownie in a mug, there is likely a desperation and special need at play that can only be met while sitting down and eating this alone. 😂 Thank you for this recipe and for this moment!

    So delicious and easy! This was my first mug brownie. I subbed wheat flour, oat milk, used regular baking cocoa and Nutella and it was so good! Wish I had some vanilla ice cream to go with it though!

    Big fan I have done several different brownie in a cup recipes this one is by far the best I have tried so far. I added 1/2 tsp extra sugar because I like it sweet and added mini chocolate chips. It was so quick and easy

    We just made the Brownie in a mug. I made mine with truvia and protein hot chocolate mix instead of the dutch chocolate. I also used Lily sugar free chocolate chips. I was fantastic. Im taking the recipe with me this weekend for my grandsons birthday so my son in law and I can have our sugar free brownie cake while everyone has birthday cake. Thank you for a great dessert!!

    I’m confused… how is this recipe different than the cake recipe? just a bit less baking powder? Cake last night was delish, star rating is for that, I’m just tryin to figure out how this is different…

    I just made the mug brownie in 6 minutes. But I added chocolate chips on top so I nuked it an additional 20 seconds to melt them. Also, sprinkled sea salt on top of melted chips. So good! If you have ever had chocolate fudge topped with sea salt, this tastes like it.

    Delicious! Thank you for a healthier single serve brownie dessert. It definitely quenched my sweet tooth without the guilt.

    I made this recipe for the first time yesterday and made it again today because it is so good. I used white sugar, unsweet almond milk, almond extract, a bit of bakers unsweet chocolate shaved into the batter, peanut oil, and I dropped in two dark chocolate truffles prior to microwaving. Then salted caramel coconut ice cream on top! It turns out like a lava cake with the melted truffles at the bottom. Make sure not to overcook- I had good success with 1 minute on high then 10 second burst x2 like Katie says!

    I tried this recipe in a microwave. It was smelling so good and turned out very delicious. Also it is very less time consuming. thank you so much

    This recipe was really delicious! It was very rich so I could only eat half of it but I did add about 1/8 cup of dark chocolate melts. Very fudge and brownie like as promised however the recipe format was very hard to read and the method didn’t really make sense. I baked it in the microwave for about 1 minute and 30 seconds which seemed to be perfect for me, great recipe will definitely be trying again! 😊
