  • 1 large egg
  • 2 tbsp unsweetened cocoa powder
  • 1 tbsp preferred sweetener I like using a little bit of raw honey, but if you are not used to making anything low carb you might prefer to start with 2-3 tablespoons of your preferred sweetener.
  • 1/4 tsp baking soda


  • In a bowl mix together the egg, cocoa powder, and sweetener. Lastly add the baking soda and mix.
  • Pour the batter into microwavable silicone cupcake liners, or 1 medium bowl (to make a small cake), or 3 small bowls (to make it cupcake size), people often use a coffee mug too. I found that one batch made 3 cupcakes. *If you are using bowls or a coffee mug you should lightly grease the inside with butter, coconut oil, or your preferred cooking fat.
  • Microwave all three cupcakes at once for 1 minute or until baked. *Note, the batter will rise very high at first and then deflate as it is finished baking.
  • Test the cupcakes for doneness by inserting a toothpick in the middle. If the toothpick comes out clean it is finished, if not microwave for a few more seconds.
