  • Mix the dry ingredients into a microwave-safe large mug, cup or ramekin.  Add the wet ingredients and mix well.
  • Add the mug into the microwave and cook for 1 minute and 40 seconds for a 600W microwave.  If your microwave is stronger, you'll need to cook it for a shorter time.
  • If you want to bake your mug cake, bake it in the oven for 22 minutes at 180/350F.
  • Once your chocolate cake is baked, feel free to eat as is or top with your favourite topping!


Note 1: Possible Sweeteners
  • 2.5 tbsp erythritol (leaves a little bit of a cooling sensation)
  • 2 tbsp Lakanto
  • 2 tbsp Sukrin
  • 2 tbsp xylitol
  • ¼ tsp stevia extract powder (pretty bitter)
  • ¼ tsp monk fruit extract powder
Note 2: Possible Nut Free Substitutions instead of the 2 tbsp of almond flour
  • 2 tsp coconut flour
  • 2 tbsp peanut butter powder (unsweetened)
  • 1.5 tbsp sesame flour
For possible topping ideas:
