The Amazing Chocolate Chip Keto Mug Cake

A moist and chocolatey keto mug cake made with coconut flour. Enjoy this cake straight out of the mug or transfer onto a plate and smother it with chocolate sauce! Sugar free, low carb, gluten free.

I used the recipe for the lemon mug cake as a starting point and began to experiment, swapping out lemon juice with cream and almond flour with coconut flour. A bit of vanilla extract here, another teaspoonful of cacao powder there…


  • 1 1/2 tbsp coconut flour
  • 1/2 tsp baking powder
  • 2 tbsp cacao powder
  • 2 tbsp powdered sweetener
  • 1 egg medium
  • 5 tbsp double/heavy cream
  • 2 tbsp sugar free chocolate chips
  • 1/4 tsp vanilla extract optional


  1. In a bowl, combine your dry ingredients - coconut flour, baking powder, cacao powder, sweetener. Make sure there are no lumps.
  2. Add your wet ingredients - the egg, cream and vanilla extract. Mix well.
  3. Stir in the chocolate chips and let the batter rest for a minute.
  4. Melt 1/2 tsp butter each in 2 mugs or ramekins (30 seconds) and grease the insides. This is an important step if you want to turn your mug cakes out onto a plate. Divide the batter between the mugs/ramekins.
  5. Microwave on high for 1 1/2 minutes. Don't microwave any longer or your cakes will become dry.
  6. Enjoy straight out of the ramekin or turn out onto a plate. See notes for an optional chocolate sauce!


  • For an optional chocolate sauce, melt 2 tbsp sugar free chocolate chips and 1 tbsp butter. I like to start them off in the microwave (30 seconds, no more) and then put them in a water bath (place a small bowl with the chocolate chips into a larger bowl filled with boiling water). Stir until liquid. Add 2-3 tbsp cream or milk and stir until smooth and pourable.
  • If you cannot get hold of sugar free chocolate chips, you can use very dark chocolate instead, with a minimum of 85% cocoa solids and break it into small pieces. I've done that for my chocolate chip cookies and it worked well.
  • Even better, make your own sugar free chocolate chips!
  • I like to use cacao powder instead of cocoa powder. Cacao powder is unprocessed, which means it retains important nutrients and antioxidants. If you are using cocoa powder, which is stronger in taste and darker in colour, you may have to halve the amount stated in the recipe.
