This protein mug cake is made with PB2 (a favorite peanut butter alternative of mine) be sure to check out more of my peanut butter recipesChoco-Mocha Nut Protein Mug Cake

I have been seeing a lot of mug cake recipes floating around Pinterest, Instagram and Facebook. The idea is great, a single serve “mug of cake”, however a lot of the recipes are higher in calories then a regular slice of cake! I’m really into protein mug cakes, they keep you full and don’t have the added calories that flour based ones have.

Some notes on this version of mug cake:

  • The type of protein powder I used was Dymatize Elite. I have used cafe mocha, cookies n’ cream and both taste great.
  • PB2 is powdered peanut butter (or peanut flour). I have it in both regular and chocolate.
  • The same goes for “Just Great Stuff”. It’s powdered peanut butter, the difference between it and PB2 is it’s organic and I’ve read that Pb2 has some added sugar. I still use both.
  • You can sub 4 egg whites for one egg, but you’re only saving ten calories so you may as well use the whole egg and get all of the benefits.
  • Don’t expect cake texture, remember there is NO FLOUR in this recipe. It’s more sponge-like.
  • Cooking anything in the microwave kills most of the nutrition but when I’m in a bind and it’s go out and buy a McCain Chocolate Cake and eat the whole thing or make a protein mug cake, I go for mug cake.

  1. Oh my goodness, Randa! This looks amazing! I’m going to have to try making this sometime this week!

    • It’s so good. My friend also just gave me a recipe for this:
      2 scoops protein powder
      4 Egg whites
      1/4 cup almond milk

      Mix and microwave 1 1/2 -2 minutes, drizzle with PB2 or melted peanut butter.

      I tried it and could only eat half it was so filling. I also added some Stevia to that version as well (I like things sweet).

  2. I have never thought to add protein powder to recipes other than shakes. This mug cake looks so good!

  3. What a neat idea! I’ll have to give this a try; I’m a protein nut too!

  4. Although I have heard of mug cakes I have never had one before! I have to say the idea of having something so tasty with such good ingredients in it is very appealing. Might have to give this one a try…

  5. I love a good mug cake! I’ve never even considered using protein powder in baking before!
