While there are a plethora of keto desserts I have up my sleeve, mug cakes are my favorite. They require minimal prep and there is no temptation to overeat, as they are portion controlled. 

Why this keto mug cake recipe will be a game changer-

  • Ready in one minute. Seriously, the bake time for this cake is just one minute, thanks to the magic of a microwave! They don’t call this a microwave mug cake for nothing! 
  • Simple and easy ingredients. No hard-to-find ingredients or unusual flours needed. You probably have everything in your pantry right now! 
  • It’s satisfying and keeps your diet on track. One mug cake satisfies your sweet tooth completely and you won’t be searching for something else after. 

What I love about keto mug cakes is just how many options there are. You can make a mug cake every single night after dinner for dessert, and have a different cake flavor every single time. We’ve included a simple keto mug cake recipe, along with 18 other flavors to try! 

How to make a keto mug cake

The Ingredients.

  • Coconut flour– Sifted to ensure there are no clumps. If you can’t find coconut flour in the grocery store, you can make your own
  • Cocoa powder– Unsweetened and sifted coconut flour. 
  • Brown sugar substitute– Also known as keto brown sugar. If you don’t have any, erythritol or monk fruit sweetener can be used. 
  • Baking powder– Leavening agent used to give the cake a slight rise. 
  • Salt– Just a pinch to balance out the sweet ingredients. 
  • Butter OR coconut oil– I prefer using melted butter, but coconut oil works just as well. 
  • Eggs– Room temperature eggs. 
  • Milk of choice– I used unsweetened coconut milk, but any keto friendly milk can be used. 
  • Chocolate chips– Skip the expensive store-bought kind and make your own sugar free chocolate chips

The Instructions. 

Start by whisking together the dry ingredients in a small bowl. Add the melted butter, eggs, and milk and whisk until a smooth batter remains. If using chocolate chips, fold them through at the end.

Now, transfer the batter into a greased mug or microwave-safe bowl. Microwave for 1-2 minutes, before enjoying immediately.

Can I bake this in the oven? 

If you don’t own a microwave or prefer not to use one, you can easily make this mug cake in the oven instead. 

Simply prepare the recipe as instructed, except for the oven option, transfer the batter into an oven safe ramekin. Bake at 180C/350F for 8-10 minutes, or until firm on top.

Frequently Asked Questions

Can I eat a keto mug cake every day? 

Keto mug cakes are single-serving desserts perfect to enjoy every single they. They are relatively low calorie and suitable for a healthy dessert option or even snack! 

Why does a keto mug cake come out dry? 

Mug cakes come out dry because of over-baking them or overcooking them. The key to the perfect moist and cake-y mug cake, is to ensure the batter is thick and smooth. It is best to undercook it and adjust the cooking time from there.

    1. OMG! Thank you so much for sharing the mug cake Recipie!! These are so simple and delicious! I’ve experimented w/other Keto Recioie before and they are usually for multiple servings. They also tasted grainy. :(. But your recipie is perfect and it’s so much easier that it’s single serving plus, the oven option too. Thank you for making my Keto diet more enjoyable.

    2. Hi, are the calories for each mug available anywhere? I’m trying to count calories but these look healthy and delicous enough to try. Thanks

    4. 5 stars
      I’ve made many mug cakes, and this is hands down the best one EVER. I made the choc-chip one (as you do), will definitely make more. One bite & I was like, OMG this is amazing! Jumped back on the low carb wagon just a few days ago and already super grateful for your recipes.
