What is a Mug Cake?
A mug cake is a single serving cake that is cooked in a mug in the microwave.

This specific recipe is higher in protein and lower in sugar. It is also made without white flour and without eggs.
Ingredients & Substitutions
These are the main ingredients and substitutions for this protein mug cake. Scroll down to the recipe card for full ingredients list and instructions.
Oat flour is a great healthier flour option. If needed, replace with 3 tablespoons almond flour. Almond flour is grain free and Paleo.
Cocoa powder adds the classic chocolate flavor.
Use vanilla or chocolate protein powder. I highly recommend using one with a good flavor. Sometimes protein powders have a bad aftertaste. In addition, whey protein does not bake well. For that reason, I recommend pea protein or another plant based protein powder.
Baking powder helps leaven this mug cake slightly.
Coconut sugar adds a natural sweetness. This popular Paleo sugar alternative is great for this healthy mug cake recipe.
Dairy free milk helps thin out the batter. Use almond milk, coconut milk, cashew milk, or coconut milk.
Lastly, mini chocolate chips add an indulgent flavor!
Taste & Texture
This protein mug cake tastes like a rich and decadent chocolate cake.
In addition, the texture is light and fluffy, with a slightly chewy crust around the edges.
The protein powder gives the cake a subtle boost of protein, but it does not overpower the flavor.
How to Make
First, add all ingredients to a mug or ramekin.
Stir to combine.
Then, microwave on high for 60 seconds. Then, microwave in additional 10 second increments as needed.
Carefully remove the mug cake from the microwave. Immediately sprinkle some chocolate chips on top.
Finally, serve this high protein mug cake!
