  • microwavable mug or ramekin



  • Lightly grease a microwavable mug or ramekin (3 inch diameter).
  • I a small bowl, stir together the coconut flour, cocoa powder, baking powder, sweetener and optional pinch of salt with a fork. Break up any clumps. 
  • In another small bowl, combine the nut milk and the peanut butter. Then, add the dry ingredients to the wet and stir until a brownie batter forms. 
  • Last, fold in the chocolate chips and fill the batter into the prepared mug or ramekin. Microwave on high for 60 seconds (900W). See suggested microwave timings in the notes below.


5.7g net carbs. Makes 1 single serve brownie.
Without the chocolate chips: 176 calories, 4.1g net carbs.
Microwave timings will vary according to the wattage of your microwave. Mine operates at 900 Watt.
Below are suggested timings for different power strengths:
  • 600W = low power. 80 seconds
  • 800W = 70 seconds
  • 900W = 60 seconds. 
  • 1000W = 50 seconds
  • 1200W = 40 seconds 
For a super duper fudgy brownie, lower the cook time by up to 15 seconds.
