Chocolate Chip Peanut Butter Protein Mug Cake Ingredients & Tested Substitutions

  • Vanilla Protein Powder. You can use whey protein powder, vegan protein powder, or whatever your favorite protein powder is. My personal favorite brand of protein powder makes a grass-fed beef protein powder that I find both incredibly delicious as well as easier to digest than a whey protein.
  • Oat Flour. Be sure to look for certified gluten free oats if you are gluten free. If you have oats at home & do not want to buy oat flour you can simply add 1/3 cup to a blender and pulse until fine. You can use almond flour for a low carb option, but I find that oat flour provides a better texture.
  • Powdered Peanut Butter. I like to use peanut butter powder to infuse the peanut butter flavor without a lot of extra calories or fat.
  • Milk. You can use whatever type of milk you prefer. My personal favorites are non-dairy milk like oat milk or unsweetened almond milk.
  • Egg. This recipe calls for one large egg. If you’re making a vegan protein mug cake, you can use 1 flax egg instead.
  • Vanilla Extract. This isn’t necessary, but I find it adds a nicer flavor to the protein mug cake. Opt for a high quality vanilla extract for best results.
  • Baking Powder. Since we’re using gluten free flours as opposed to an all purpose flour, adding baking powder helps the mug cake rise.
  • Chocolate Chips. Dark chocolate or milk chocolate chips will work.

Note that there is no added sugar in this recipe. The protein powder I prefer has a touch of monkfruit in it, so additional sweetener isn’t needed. If your preferred brand isn’t sweetened and you’d like to add sweetness, you can add 2 tsp of maple syrup, coconut sugar, white sugar or your preferred sweetener of choice.

Step By Step Instructions For This Protein Mug Cake Recipe

  1. Prepare the batter. In a large microwave-safe mug or large ramekin, combine the dry ingredients (protein powder, oat flour, baking powder and powdered peanut butter) with the wet ingredients (egg or flax egg, milk and vanilla extract), whisking vigorously until no clumps remain. The batter should be the texture of cake batter. Add in half of the chocolate chips, stirring to fully incorporate them into the batter.

2. Cook the mug cake. Place the coffee mug or ramekin into the microwave. Microwave for 50 seconds, then stir and check the texture. Depending on the power of your microwave you may need to cook an additional 10-20 seconds, but do this in 5-10 second intervals to avoid the mug cake taking on a rubbery texture. Once cooked, top with the remaining half of the chocolate chips.

Protein Mug Cake Recipe FAQs

When is the best time to eat a protein mug cake?

This delicious mug cake can be enjoyed as a quick breakfast or a healthy snack. Of course it’s always a good reason to enjoy dessert, too, especially when that cake craving hits!

Can I store protein mug cake?

Protein mug cakes are meant to be enjoyed right away. I do not recommend making them ahead of time and storing them, however if you can’t finish the entire serving, you can always cover your mug with plastic wrap and keep it in the fridge. You can warm it back up in the microwave when you’re ready to enjoy it again, just note the texture may change depending on the brand of protein powder you’ve used.

What type of protein powder should I use?

Any type of protein powder will work for this recipe. Use your favorite! I prefer to use vanilla flavored protein powder, but you can use unflavored or you can used chocolate protein powder to make this a peanut butter double chocolate protein mug cake recipe! If you’re looking for a helpful guide on easy to digest protein powders, check this post out!

What if the mug cake is too liquidy?

Occasionally, depending on your microwave, you may find that your protein mug cake hasn’t fully cooked through and is still a bit liquidy on the inside. If this happens, simply place the mug back in the microwave and cook in short 5 second intervals until a cake-like texture is achieved.

Where do I find oat flour?

You can find oat flour in many grocery stores or on Amazon. I like Anthony’s and Bob’s Red Mill gluten free oat flour. You can also make your own oat flour at home by adding oats to a blender and pulsing until fine.

    My buddy Chris shared this. It was dope I more or less had all the ingredients (subbing in chocolate protein powder and peanut butter chips) around the house. Loved the suggestion to blend up some oats to make my own oat flour. Yeah. Delicious hit the spot and I’ll do it again!
