Oven baked option in notes

Microwave Mug cake 

  1. Whisk dry ingredients together in a bowl (flour or protein powder, salt, sugar, baking powder) 
  2. Next, place oil, vinegar, and vanilla in three different spots on top of the dry mix. (see video in post)
  3. Pour milk over the top and gently stir. You will see a few bubbles.
  4. Pour this mixture into greased microwave mug or ramekin. If using pea protein or cassava flour, the batter will be thicker. Use the back of a spoon or your fingers to gently press the mixture down into the mug.
  5. Microwave on high in 3 intervals of 30 seconds each time, check to see if the cake is firm. If not, cook 15-20 seconds again. Total time depends on microwave power. The top should be firm to touch once cooked. Remove from microwave, let it cool a minute.
  6. Dig in with a spoon or flip over onto a plate . Toppings optional but a good scoop of yogurt or coconut whip is divine! 


Alternative flours * Pea protein and cassava flour are thick. If you use them, you will need to gently press the mixture down into the mug with a spoon or your hands. Texture and microwave times will vary.

Oven baking option –  Bake at 350F for 15-20 minutes in ramekin. Check at 15 minutes for doneness. Serves 1

CHOCOLATE MUG CAKE – The ingredients you need to make the chocolate mug cake are the same as the vanilla version, with two exceptions.

  1.  If you are using protein powder, use chocolate instead of vanilla.
  2. Mix in 1/2 tbsp of unsweetened cocoa powder with the 3 tbsp protein powder or oat flour. Dark chocolate chips go on top or mix in batter.
