We love high-protein recipes, and we have shared so many, like my Strawberry Protein Balls, Protein Oatmeal Cookies, or Overnight Oats with Protein Powder. Our most popular are the homemade protein bars or our protein powder mug cake.
What Is This Protein Cake?
This protein cake recipe is inspired by our protein powder mug cake, usually microwaved in a ramekin. Here we turned the recipe into a family-size protein cake recipe, a larger version of our favorite protein snack, baked in less than 25 minutes for a quick healthy cake. If you love a moist, fudgy chocolate cake but want to keep it healthy and packed with wholesome ingredients, this protein cake is what you need.
Ingredients and Substitutions
All you need are a few simple ingredients:
Oat Flour – Oat flour is simply made from rolled oats pulsed into a thin flour-like texture. Check my tutorial on how to make oat flour if you need it. Chocolate or Vanilla Protein Powder – We use clean pea protein powder made with just three ingredients. You can also use almond protein powder or peanut protein powder. Unsweetened Cocoa Powder – I prefer to use unsweetened cocoa because it makes it easier to balance the sweetness. Non-Dairy Milk of Choice – Soy milk is high in protein, but almond milk or oat milk are also great options. Baking Powder – This gives the cake a soft and fluffy texture. Yogurt of Choice – High-protein soy yogurt is our favorite. It also works with cashew yogurt and coconut yogurt, but the latter gives the cake a slight coconut texture. Maple Syrup – Any liquid sweetener works, such as coconut nectar, agave syrup, or rice malt syrup. Sugar-free alternatives also work.
