Keto Chocolate Mug Cake

I jumped on the bandwagon… I figured I needed to test a mug cake recipe to share with y’all since my intention is to make it easy for you to create family friendly recipes that are easy to make. To be honest, I didn’t expect much from it; a cake that’s ready in 50 seconds and doesn’t even see the inside of an oven! (blasphemy! LOL) Anyway… I have been proved wrong. This recipe satisfied my sweet cravings, had a really good bite to it and, looked super pretty (dinner party / date night desert idea maybe?) and was immediately approved by my test team (aka 9 year old daughter). Give it a try!


  • 2 tbs almond flour
  • 1 tbs cocoa powder (make sure to sift it or give it a stir before measuring it because if it has clumps in it the amount measured will be denser and result in a less sweet and more bitter cake)
  • 1 tbs keto friendly sweetener (be careful if you use pure Stevia since it has bitter components and if you combine that with cocoa powder it will probably result in a bitter cake. I used erythritol)
  • 1/4 tsp baking powder
  • 1 tbs (avocado)mayonnaise (if you don’t have mayo on hand, you can substitute sour cream)
  • 1 large egg yolk
  • 1 tsp water


  1. Measure the dry ingredients into a mug and mix until well combined. TIP: try to avoid using narrow or high mugs since those make it harder for the cake to bake evenly.
  2. Add the mayo, egg yolk and water and mix well, making sure to scrape the bottom to make sure all dry ingredients will be mixed in.
  3. Let the batter sit for about 2 minutes.
  4. Microwave for 50 seconds (as always; microwave oven cook times may vary)
  5. Let cool for a bit before serving with whipped cream if desired. So good!

What I’ve learned…

  • It really DOES make sense to stir or sift your cocoa powder before measuring. Stirring with a whisk is easier and works great, just make sure you get rid of all clumps.
  • You can not taste mayo in baking creations.
