Keto Mug Cake

A single serving keto mug cake recipe so soft, so rich, so chocolatey… and definitely not meant for sharing!

Low Carb Chocolate Mug Cake

This is possibly one of the most indulgent chocolate mug cakes you will ever try.

A brownie-like chocolate cake in a mug, made without flour, eggs, dairy, or oil.

It will completely solve all of your chocolate cravings… in less than 1 minute!

Ever since I posted my original Vegan Mug Cake Recipe –which is one of the biggest reader favorite recipes from this blog—people have been asking me to come up with a low carb or flourless version.

Over the years, I’ve experimented with coconut flour, peanut flour, and almond meal; and finally I’m happy with the results.

This chocolate healthy mug cake is everything I’d hoped it would be. You won’t miss the flour one bit!

The Best Keto Cake In A Mug

Honestly, this cake is so rich that it might be more fitting to call it a chocolate mug brownie instead of a cake.

The taste reminded me of the Ultimate Unbaked Brownies, so if you like that recipe, you will probably like this one too – it’s like eating a batch of unbaked brownies with a spoon!

You can choose to use nuts or almond flour for this keto mug cake with no egg, whatever is easier.

I’ve listed the three variations below that I’ve tried (almonds, pecans, and almond flour), but I bet others could work as well.

If anyone tries the recipe with walnuts, cashews, or cashew flour, definitely be sure to report back!

If you need it to be a keto dessert, be sure to use a keto-friendly sweetener such as xylitol or erythritol, and choose a sugar-free variety if including chocolate chips. I’m not on the keto diet, so I just added some regular chocolate chips to the top and let them melt into the warm chocolate cake.

Sometimes I make really good decisions.

Keto Mug Cake

This single serving keto mug cake recipe is so soft, rich, and ultra chocolatey!
4.91/5 (145)
Cook Time 1 minute
Total Time 1 minute
Yield 1 cake


  • 1/3 cup almonds or pecans, or 6 tbsp almond flour (nut-free version here)
  • 1 tbsp + 2 tsp cocoa powder
  • 1 tbsp granulated erythritol or sugar or sweetener of choice
  • pinch stevia, or additional 2 tsp sugar
  • 1/8 tsp salt
  • 1/4 tsp baking powder
  • 3 tbsp milk of choice, or 2 if using liquid sweetener
  • 1/4 tsp pure vanilla extract
  • optional chocolate chips or sugar free chocolate chips


  • *If using almonds, grind them in a blender or food processor to achieve a flour-like consistency. It will be coarser than if you use almond flour (hence the almond pieces you can see in the photos), but both versions work.
    Combine all ingredients in a greased ramekin or small mug. Either bake in a preheated 350F oven for about 10 minutes, or cook in the microwave. If microwaving, time will vary depending on wattage and desired gooeyness. I started with 30 seconds, then added two 15-second intervals after that. The cake will look a bit gooey when it comes out, and it firms up as it cools. But there’s no need to wait for it to firm up too much – this cake is meant to be eaten straight from the mug!

    Totally loved this! It was so delicious and easy to make…my dad (who’s on the keto diet) said it was one of the best desserts he’s ever had.

    • CCK Media Team says

      Hi, we are confused by this comment but want to help – what do you mean by “no amounts”? Is the recipe not showing up for you?

  2. Lacy says

    Amazing!!! I have tried so many keto recipes and this is my favorite. I didn’t use vanilla cause I was out of it and i put 1tsp of coconut flour in it. It was absolutely perfect!!!

  3. Stephanie Leigh Cote says

    Hello! I just made it it’s a quite a big mug cake so I only was able to eat half of it extremely rich. I used powdered Swerve and monk fruit .. and I used heavy cream instead of milk .. after mixing it was a tad to thick/dry so I added a little water. Mixed in Lily’s milk chocolate chips.. it was DELICIOUS!

  4. Vanessa says

    Wow!!!! Who are you? MUAH. This is by far the best keto desert I’ve had in the 10 months Ive been on keto. I had it with Bryer’s Carb control vanilla ice cream and mine was more of a brownie. It was perfect….thanks 😃

    • Vanessa says

      Oh, and I used a tad bit less almond flour and heavy cream. Also added a splash of butter flavored extract along with the vanilla.

  5. Jennifer says

    This is perfection. Amazing consistency. Easy recipe. It’s everything a keto mug cake should be and takes care of those chocolate cravings!

  6. Mary says

    Was a perfect keto friendly treat. Very rich chocolate cake. Mistakenly added double amount of baking powder and still turned out great. I cooked in microwave for total of a minute. Had run out of eggs, so thiswas a save for the day. 🙂 Will definitely make again and will either cut cocoa or increase sweetener.

  7. Mrs_H says

    I can’t wait to try some of your keto dessert (cake, brownie and ice cream) recipes, but why don’t you put the nutrition facts ON the recipe? When I print out your recipes (I like to keep a paper recipe) it doesn’t have the nutrition facts on it! Thanks.

    • Montana says

      While this was way yum, your nutritionals are WAAAY off. You list it as 195 calories … 6 T almond flour alone is 240 calories. The entire thing, after I ate it and THEN logged it, was 350 calories. Disappointed I didn’t look first. 🙁

  8. Justine B. says

    Mine turned out like soup, but it had seemed so dry as a batter. No clue what I did wrong with the texture, but it tasted ok.

  9. Lucy says

    Hands down the best keto baked good I’ve ever tasted ! How can something taste so good with no sugar or butter in it ???? I knew it was gonna b good because I couldn’t stop eating the batter!! It took less than 5 minutes to make. This is perhaps too delicious. And too convenient. I fear I’ll b making one every day ! Saved it in my recipe folder. This cake makes me love my keto
    Life !!! My cat just died so this was a “stress bake”. Thank u for bringing me a little bit of joy. RIP Romeo

  10. Eric says

    Disregard my previous comment, I went ahead and added a TBSP of chocolate hummus and and an extra TBSP of heavy cream. It was quite tasty, but it never really firmed up. I see that it says that “gooey” is the point, but just making sure that it’s supposed to end of as more of a superthick paste-like consistency. Also, how come no egg?

  11. Deb Warren says

    This mug cake was SO TOTALLY DELICIOUS!!! We will make it again and again! Thank you so much for publishing the recipe!

  12. Sophia says

    some of the comments mention eggs but the recipe didn’t call for it. This was my first time making a keto mug cake, first time using almond flour, monkfruit with erythritol. It did not come out like a cake, it came out like a delicious chocolate pudding. It was so good I don’t want to know where I went wrong. I made it with almond milk, as well. Fabulous fail I will make again and again.

  13. Peter says

    Hello Katie, I just made this Keto Mug Cake and it was awesome. I am a diabetic, so next time i will use either Stevia or Erythritol instead of the sugar. I didnt want to invest the money until I tried it out. I am always on the lookout for healthy desserts, I usesd Natural Almond Flour, Almond Milk and Dark Chocolate chips. I have to remember to grease the mug so it rises more. I may try Coconut Flour as well just to see what it comes out like. But again this was delicious and relatively low-carb. Thanks again for Posting your recipes

  14. Sarah says

    I am sad to report that one should not trust the nutritional information provided. Above, the recipe calls for 6 tablespoons of almond flour, which amounts to 255 calorie (Almond Breeze brand, 1.5 servings= 170 cal each 1/4 cup). So how is the whole cake 195? Very disappointed to find out information cannot be trusted.

  15. Sandy says

    I was very disappointed in this recipe. It did no raising at all. I used almond flour & almond milk (milk of your choice) per recipe. I made a 2nd recipe for my husband knowing he wouldn’t eat this one. The other recipe used butter & egg which doubled the calories. It rose most of the way up his mug & he said it was great…I didn’t wasn’t the calories, so how can I make this recipe work?

    • CCK Media Team says

      Hi Sandy, it is not supposed to rise a ton. It’s more fudgy like a brownie cake. So you made it correctly! 🙂

  16. Gretchen says

    This was very tasty. I used half and half for the milk and only had mini nestle morsels. Will buy sugar free chocolate chips my next trip to the store. I would definitely recommend this to get your chocolate fix.
