What is a Mug Cake?

A mug cake is a single serving cake that is cooked in a mug in the microwave.

Mug cakes are typically made with simple ingredients like flour, sugar, eggs, and milk.

They are a quick and easy way to enjoy a sweet treat without having to turn on the oven.

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!
