Instructions to Make Keto Chocolate Mug Cake

Be very careful using the only stevia to sweeten chocolate baked goods. The bitter composites in stevia and the bitter aggregates in chocolate have a synergistic effect. It can make your treat quite bitter!

The preparation

Fluff the almond flour with a whisk before measuring and filter the cocoa powder if it is clumpy. You can sift the cocoa and keep it in an air-tight container. It will break apart any lumps for more precise measuring when making this mug cake.


  • Measure your dry ingredients into a mug or jelly jar and mix thoroughly with a fork.
  • Then add the mayonnaise, egg yolk, and water, stirring thoroughly. Make sure to get it all from the bottom. Let the mix sit 1-2 minutes.  
  • Microwave everything for about fifty seconds, depending on your microwave.

Although the texture is a little different, one large egg white can be used instead of the giant egg yolk, solving the problem of a leftover egg white. 

To really take this cake to the next level, try some of these ideas.

  • Top the cake with whipped cream or whipped coconut cream.
  • Try to add 1/16-1/8th teaspoon flavoring extract to the batter.
  • Add a few berries to the batter.
  • Maybe try sprinkle cinnamon, cocoa powder, powdered sweetener, or grated chocolate on top.
  • Add a spoonful of sugar-free jelly in the center of the batter.
  • Put a spoonful of sugar-free chocolate hazelnut and spread in the center of the mixture.
  • Try a small square of dark chocolate in the middle of the mixture before cooking.
  • Top with sugar-free homemade hot fudge or store-bought sugar-free chocolate sauce.
