Eat plain or top with coconut butter or my recipe for Healthy Glaze Icing.

P.S. My computer’s spellchecker keeps suggesting I change the word streusel to stressful.

Definitely not the same thing!!

Banana Cake For One

Banana Cake For One

Total Time: 5m
Yield: 1 Mug Cake
Print This Recipe  4.97/5

Ingredients

  • 3 tbsp spelt, white, or oat flour
  • 1/4 tsp baking powder
  • 1/16 tsp salt
  • pinch stevia, or 2 tsp sugar
  • 1 tbsp plus 2 tsp water
  • 1 tbsp overripe mashed banana (Banana-Free Version Here)
  • 1/4 tsp pure vanilla extract
  • For the top, combine: 1/4 tsp cinnamon, 2 tsp brown sugar or xylitol or sucanat, 2 tsp overripe mashed banana, tiny pinch salt, 1 tsp buttery spread OR 1 tsp more mashed banana, optional crumbled pecans or walnuts.

Instructions

Grease a small mug or 1-cup dish, and set aside. In a small bowl, combine all cake dry ingredients, then add all cake liquid ingredients and stir. Transfer the cake batter to the prepared dish, then spoon the streusel evenly on top. Either bake at 350F for 14 minutes or until a toothpick comes out clean OR cook in the microwave until a toothpick comes out clean. (Microwave times will vary depending on wattage.) If you don’t want to eat the cake directly from the mug or dish, allow it to cool completely. Then run around the sides with a knife and it should pop right out! Eat plain or topped with coconut butter or my Healthy Glaze Icing, linked earlier in the post.

    Sounds delicious – if we had a microwave! 🙂 I’m going to have to look around at your other recipes, though. Grandma’s Famous Snickers Bars look tempting.

    However, you tagged it as gluten-free, but you list spelt, white or oat flour. I’ve been learning a lot about this since my mother was diagnosed as gluten-intolerant last year. Spelt has gluten. Although oat flour technically *should not* have gluten, I know my mother can’t tolerate it. I want her to try Bob’s Red Mill gluten-free oat flour, but she’s had such bad reactions to oats that she’s nervous. Have you found success with a certain brand?

    • Hannah says

      Just Plain Marie – i eat gluten free and i use Pamela’s gluten free flour mix of Bob’s Red Mill gluten free flour blend, but i like Pamela’s better
      PS: this is unrelated but grandma’s famous snicker bar’s is not a recipe from this blog

      • Just Plain Marie says

        I realized that after I clicked through. However, I then came back and looked through your stuff. 🙂 So you didn’t lose a reader. I shall definitely have to keep an eye on your recipes and pass some along to Mom.

          • Just Plain Marie says

            Okay, I’m looking like more and more of an idiot. Not that that’s particularly unusual some days!

            I got your reply in my email, came through, couldn’t find it, so just made a new comment. THEN as I’m looking at the pretty picture in the About, I’m thinking “Katie? Wait? Wasn’t it Hannah that I responded to? Oh, must have been a guest writer.”

            Can I pretend it’s still Monday? 😀 Besides, there’s a comment from sassygirl to Hannah about “ingredients for your mom” and I think she means me, not Hannah. 😀

          • Hannah says

            oh its fine!i would of been confused also!
            i also am kinda confused- you are the one who needs a gluten free mix without oats, not me!

    • sassygirl says

      hi Hannah!
      please check the ingredients for your mom,
      but I’m a huuuuge fan of nuts.com and their
      gf all purpose baking flour. it has NO xanthan gum
      included in the mix and I have been baking Katie’s
      recipes, waffles, cookies with great results.
      you can find the co. online. ships really FAST. 🙂
      good luck!

    • Mia (Mia in Germany) says

      Just Plain Marie,
      I don’t have a microwave either, but I’ve made this kind of cake in the oven often. You can just bake it at 350°F for 12-15 minutes (that’s what usually works for me with recipes like this one) 🙂

    • Rose says

      I found gluten free oats ay a grocery store for a decent price. Quaker makes them. I haven’t tried it yet but I hope to make energy balls soon with these oats.

  2. Hannah says

    i cannot wait to make this! hopefully i can run to the store real quick and grab some bananas so i can make this! thank you for the recipe!

  3. Sara K. says

    This looks like a great addition to my breakfast options. Like Kathryn mentioned, this wouldn’t be a stand-alone breakfast for me, but I can definitely eat it along with something else to make a good (and yummy!) start to my day!

      • Sara K. says

        I didn’t think you were implying that either 🙂 I’ve been reading your blog long enough to know that you are in full support of all-around healthy eating (not starving ourselves!)

        I’m not actually a vegan, so for me this would pair well with an egg or a yogurt to give me a well rounded breakfast. Currently I’ve been eating an english muffin most morning so I will just sub this in to make a yummy treat!

  4. Bob says

    Would this recipe scale up if I wanted to make a whole loaf of bread like this? Or, does anyone know of a similar recipe to make this on a larger scale? Thanks!

    • Anna says

      Katie does have a few loaf recipes (including banana bread, just type in the search bar) if that’s what you’re looking for

  5. Bob says

    Does this recipe scale up to make a whole loaf with it, or is there a similar recipe that can be used to make more? Thanks!

  6. Maddie says

    I got your book in the mail yesterday!!!!!!!!! I haven’t had time to pour over it yet but I am SO excited to get into it. Yay!!!!

    🙂

    • EVA says

      Check out YouFreshNaturals.com or their Instagram. They’re the makers of the GF/vegan coconut butter in damn delicious flavors, and their recipes are 100% paleo and the directions look so easy. I actually had to stop looking at their Instagram because I’d get viciously hungry every time I’d see their new “creation”, and I can’t eat paleo because of my bad gallbladder. But check ’em out, make their recipes, and make me jealous!

  7. Bird says

    This looks awesome, and I must say I am loving your new cookbook! Just made the flourless oatmeal cookies and they are hard to put down! Question: When are you going to come out with a single serve cookbook?? 🙂 Thanks for all of your recipes Katie!

  8. Avra-Sha Faohla says

    Just made these, and they were delicious, but I was confused about the streusel. Mine was liquidy, not crumbly like a normal streusel. I guess it makes sense that it would be like that because it has no flour and it has mashed banana (which is basically a liquid). But the word “streusel” is confusing. Do you think maybe you should stick with “topping”?

  10. Keri says

    Hi Katie!! I am in love with your site!! Great recipes that are easy to follow and the pictures look so tempting! I will definitely be back for more recipes in the future! I have a healthy eating blog as well and love getting new recipes to try as I’m not much of a baker. I will be linking to your site on my blog! Keep up the great work!!!

  11. Inge says

    Yum! Those sound perfect for early days at the stable. I can make them while I get ready and then eat them on the bus. They might even get me to conquer my fear of the microwave. Thanks! 🙂

  12. Joey says

    Just read the banana-free link… So oil can be subbed for mashed banana or applesauce… Oh my God Katie this is a game changer! Suddenly I can take a crack at sooo many recipes! Thank you so much!!! 😀

  13. Chris says

    I’m planning on trying this with almond or coconut flour in the next few days to make it truly paleo. I’ll try to remember to let you all know how it goes.

  14. Katy says

    Yum!! I made this for breakfast today and it totally hit the spot. I had a pretty intense workout last night and woke up ravenous – oatmeal alone just wasn’t going to cut it 😉 Thanks for another great recipe! Love the banana in the streusel.

  15. Kelly Wang says

    Made this on a rainy night, after dinner. I used 1TBSP chickpea flour, 1T almond flour, 1T oats, some coconut flakes, some pysillium husk, because I was feeling adventurous. Holding a warm mug of banana cake with melty chocolate .. hmmmm

  16. Jessica says

    I just made this for dessert and oh. my. gosh. It was literally heaven. It was so delicious that I had to make another one after because it was that delicious. The brown sugar topping was my favorite part. I’m so glad I tried this out tonight, I’ll definitely be making two more tomorrow morning for breakfast 😉 Your recipes never fail to disappoint!

  17. Betsy says

    I think my kids are going to have so much fun making this! They’ll feel so special, each getting their own mug muffin that they made themselves.

    Is there any more specific information about the microwave times? I don’t want to overcook it by not putting hte toothpick through at the right time…is there maybe a range of times for making it this way? Thanks 🙂

  18. Maria says

    Hi, Just wondering if I missed a post explaining why you have stopped posting weight measurements. Really like those. Thanks

  19. Gen Smiley says

    Me and my boyfriend love this recipe! It is sooooo yummy and easy to make! Could you please tell me how to convert this into a regular cake size? Maybe for an 8 x 8 pan?

    Thanks so much!

  20. Meghan @ Freezer Friendly Moms says

    I am so excited to make this!! What a special breakfast treat…or a healthy late night snack! Thanks for sharing!

  21. Andrea says

    I cooked mine in the microwave for 35 seconds and it came out perfect! My banana was not over-ripe (actually it was barely ripe), but it came out fine! I could see how a riper banana would be even tastier though!

  22. Rachel says

    WOW. I made this exactly as the recipe states (except I forgot to use oat flour and used whole wheat instead). It is AMAZING. Thank you Katie for coming up with these wonderful single-serve recipes. I microwaved it for 1 minutes and 15 seconds and it was exactly right. I am enjoying it right now with a cup of coffee and it’s perfect for this rainy day we are having here. Keep up the good work!!!!

  23. Pamela says

    I had 1 medium sized banana and wanted to use it all for this receipe. I was successful in making 7 (could have stretched to 8) muffins out of it. I increased the servings size to 6. Below was my increased calculations for others:
    1 cup + 2 tbsp flour
    1 1/2 tsp baking powder
    1/3 tsp salt
    1/4 cup sugar
    1/2 cup and 2 tbsp water
    1/3 cup banana
    1 1/2 tsp vanilla extract

    1 1/2 tsp cinnamon
    1/4 cup brown sugar (this equals to 4 tbsp, but I acutally used 3 tbsp and in tasting thought it tasted sweet enough)
    1/4 cup banana
    2 tbsp butter
    pinch salt

    Great recipe Katie. Thank you.

  24. Cinerdy says

    Oh man. I stumbled across your blog while looking up various snack bars, and I think I’m addicted now. Thank you for your existence. Going to try loads of these recipes this week!

  25. someone says

    I added chocolate chips to mine, and replaced the sugar with maybe even less than a teaspoon of honey. Then I topped it with low-fat yoghurt (which had about a teaspoon of honey mixed in) and banana slices – tasted great!

  26. Anna says

    I tried this a couple days ago for breakfast and it was amazing!! I used half oat half brown rice flour and it rose beautifully and tasted amazing!! I LOVED the cinnamon streusel on top as well! thank you so much for the great recipe!

  27. caz says

    +I made these as I wanted a peanut butter fix so simply added peanut butter to the recipe and used honey instead of sugar , thought a bit of cinammon would be nice in it too but only thought of that after so sprinkled some on top , did not add vanilla , could probably have used less flour than I did but on the whole it was yummy especially WARM straight from the microwave and a mug took 2 minutes to cook through , am happy with this recipe and you can adapt it to suit 🙂

    My puppy had some too as he loves peanut butter and bananas and a little cinammon is ok for dogs too!

  28. Getsuyuki says

    Just made this for tea break. Love it so much! Thanks a lot for the wonderful recipes as always <3

  29. Annika says

    Am I the only one who increased the liquid amount??
    With that little water and just 1 Tbsp ripe banana I had nothing but Streusel with 3 Tbsp of flour ( I use spelt)…. I doubled the liquids and that works better…added some Matcha powder and 1tsp poppy seeds 🙂

  30. Richa says

    It took only 1.5 mins in the microwave to bake. It smelled heavenly and tasted awesome. We ate it with ice-cream for deserts. Thanks for the quick recipe.

  31. Min says

    I just made these for me and my boyfriend: I didn’t know how long to microwave them in the ramekins for so for mine (test trial) I stopped every 30 seconds just to see for a total of 1 minute. His I microwaved straight for 1 minute. Mine turned out denser/ cakier while his was more of a sponge like texture – All so delicious and the streusel topping really makes it wonderful! I’m so ready to make these again – thank you so much!

  32. Luisa says

    I made this with a teaspoon of shredded coconut and double sized banana and it turned out great! Love this recipe!

  33. Hayley says

    I made this this afternoon and it was amazing and super easy. I added dark chocolate chips to the dry mix and a dash of milk as the mix looked dry (my measurements probably went wonky) and microwaved for no more than 90 seconds on 800. Highly recommend it!

  34. Jen says

    These were amazing and so easy. I doubled the recipe for my husband and I. He loved it. Always tastes better in the oven and a great use for that banana that you didn’t eat earlier.

    hey Katie, no Greek yogurt frosting on your link from carrot cake. did the banana mug cake take over both links? want that yogurt frosting 🙂

  36. Kristen walker says

    I think im missing something but Not sure what… I used almond flour as I don’t use flour… ingredients exactly and its so dry!!! I can’t even get it to cook into cake.. the base stays crumbled but the struesel topping is amazing. What did I do wrong? It’s like there’s zero liquid in here but I added all of the water, extract, .. and extra almond milk to try cooking further 🙁 I microwaved 1.5 minutes at a time.

    • Alex says

      I’m hoping this dumb comment was left as a joke. If you used almond meal, you obviously didn’t follow the recipe even remotely and therefore know full well what you did wrong! WTF?

  37. Angela says

    Made this to appease my sweet tooth tonight! A few suggestions. I did not love the “streusel” topping, so what I did was cut down from 2 tsp sugar to 1 tsp only and threw in some chocolate chips (always better with chocolate!). Also, as a side note, I did 2 tbsp oat flour with 1 tbsp regular flour and it turned out great! Microwaved it for about 1min 15 sec and perfect consistency. Thanks for a healthy single serving dessert alternative!

  38. Makayla says

    Second day of making it for breakfast. So flippin good. My fiancé asked me to quadruple the recipe today then asked if I’d make it for his parents when they visit! Happy dancing!!! Thanks for the recipe!! (Note: Only thing I changed was I added a pinch of cinnamon to the batter and a tsp of oats to the streusel).

  39. Makayla says

    I’m taking on the challenge of making my own wedding cake and I immediately thought of this cake. Me and my fiancé love it so much (we make it like three times a week. No joke.). Just wondering if anyone’s converted the measurements to make a bigger cake?

  40. Sheree says

    Made last night, one mug for hubby and one for me. First time making cake in a mug, will not be the last. It was quick and delish.

  41. Jaime says

    This was great! Thanks! I used the American Test Kitchen gluten free blend. Topped with a big scoop of peanut butter for a calorie/protein boost and a few chocolate chips. ?

  42. Hazel says

    This recipe was very good… However when I plugged all of the ingredients into my calorie counter it came up with 199 calories, more than double of what was in the posted nutrition facts (I was hoping I could get away with making second!). I did use sugar instead of stevia, but that only accounts for 33 calories…

    • Jason Sanford says

      Hi! I’m not sure how it could be that many, because 3 tbsp oat flour is only 75 calories, and then the rest would be for the banana (if using stevia/non-calorie sweetener). But online calorie counters are often wrong so perhaps it’s really just less than yours is saying (which is a good thing haha).
      Jason

  43. Ruthie Stewart says

    This was absolutely delicious, mine didn’t rise very much and had more of a banana bread texture than cake, but that was fine, I loved it! I didn’t use the brown sugar in the topping and it was plenty sweet! Thank you Katie!
