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!
4.92/5 (133)
Total Time 1 minute
Yield 1 cake

Ingredients

  • 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

Instructions

  • *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!

    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!!!

  2. 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!

  3. 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.

  4. 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!

    • CCK Media Team says

      It would probably be too dry and you’d need to play around with the liquid ingredients to make it work 🙂

  5. 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.
