Print Recipe


  • ½ teaspoon coconut oil
  • 1 tablespoon low carb sweetener
  • ½ teaspoon vanilla extract
  • 1 large egg see note for egg-free
  • 2 tablespoons unsweetened cocoa powder
  • 2 teaspoons coconut flour
  • ½ teaspoon baking powder
  • tablespoons heavy cream more or less


  • Melt coconut oil and sweetener in microwave for about 15 seconds.
  • Stir in vanilla extract.
  • Add mixed dry ingredients (cocoa powder, coconut flour, and baking powder)
  • Stir in heavy cream until thick brownie batter forms.
  • Microwave anywhere from 30-90 seconds to texture desired (less for fudgy brownies, longer time for cake-like)
  • Serve warm topped with whipped cream, if desired.



Brownie can be made in a coffee mug, ramekin, or any similar sized microwavable dish.
To make the recipe egg-free, use a fiber syrup in place of the sweetener and omit the egg. Or a psyllium or flax egg can be used with granular sweetener.
