Bonus, this is also a vegan mug cake made without eggs or dairy. I love making quick and easy snacks that help me boost my protein. Having more protein after a workout makes me feel better and it’s proven to be an important part of muscle recovery (source). I often make my Strawberry Protein Balls or Low Calorie Protein Balls and if I planned things ahead (not my forte though), I make my Overnight Oats with Protein Powder. This protein powder mug cake is what I make when I want one of these recovery snacks, but I’d rather have something warm. It’s a protein powder alternative to my Protein Mug Cake.

What’s A Protein Powder Mug Cake?

A Protein Powder Mug Cake is a single-serving cake made in under 5 minutes using a microwave. It’s loaded with protein powder to make a great post-workout snack.

Ingredients and Substitutions

To make a delicious mug cake with protein powder, the main important thing is to use a protein powder that you already know and enjoy its flavor! All you need for this chocolate protein powder mug cake are:

Plant-based Vanilla Protein Powder – you can use vanilla, coconut, or chocolate flavor. This is up to your taste but plant-based, pea protein powder provides the best cake texture. We didn’t try the recipe with animal-based protein powders, like whey protein powder which usually requires more liquid to achieve the same baking texture. Unsweetened cocoa powder Crystal sweetener – to keep this recipe low in calories and sugar but still satisfying to your sweet tooth, we recommend using sugar-free crystal sweeteners like erythritol. But coconut sugar or table sugar would also work just fine. Avoid liquid sweeteners like maple syrup. They make protein powder mug cakes very dense and chewy. Oat flour – Oats are another great source of plant-based protein in your vegan mug cake, and you can make homemade oat flour in a minute. Other options for a keto mug cake are to use keto flour, like 1 tablespoon of coconut flour instead of the 3 tablespoons of oat flour. Almond milk or any non-dairy milk you have at home like oat milk, soy milk, or coconut milk. Baking powder

Choice of Protein Powder

I tested this recipe with plant-based protein powder only, including:

Pea protein powder Almond protein powder Peanut protein powder

The texture of the mug cake differs based on the protein powder you use, as some are more liquid absorbent than others. So when cooking with protein powder, whether you are making this vegan mug cake or my protein overnight oats recipe, always adjust the recipe if you use a different kind of protein powder. You only need 6 ingredients to make this protein powder mug cake recipe, and the key to success is to measure your ingredients with regular measuring spoons. We don’t recommend using the scoop provided with your protein powder because they all have different volumes and result in inaccurate measurements.
