  • Mix all of the dry ingredients in a medium bowl (almond flour, sweetener, baking powder, unsweetened cocoa powder)
  • Combine and mix the wet ingredients (eggs, peanut butter, vanilla, and melted butter) in a separate bowl. The peanut butter (natural) will be thick and runny. You do not have to fully dilute it while stirring. Just stir enough so everything is combined. 
  • Add the wet ingredients to the bowl with the dry ingredients. Mix well until fully blended.
  • Fold in the chocolate chips and stir.
  • Spray a mug with cooking oil. Add the mixture to the mug.
  • Microwave for 50 seconds to 1 minute. I timed it for 50 seconds because I wanted a really moist cake. With 1 minute it will be slightly more firm, but still moist. 


If you overfill your mug, the contents will drop along the sides, very similar to the photos above!
If you do not wish it to overflow, only fill the mug 3/4 to the top.
For me, one mug was way too much for one serving. So I divide the mug in half.
