A decadent chocolate cake for one bakes up spongy and light in the microwave! This tasty Protein Mug Cake is a calorie splurge, but the addition of chocolate protein powder means that it is super satisfying in more than one way.
Why This Protein Mug Cake Recipe is So Good
- It's a Really Delicious Cake - I've had protein powder mug cake made with just protein powder and eggs, and they're really not that good. My recipe uses protein powder, but also almond flour, cocoa powder, sugar, and vanilla to ensure that this cake is as delicious as it can possibly be.
- Light and Fluffy Texture - a few secret ingredients (ok, it's baking powder and cornstarch) ensure that this mug cake microwaves into a fluffy, soft, airy cake.
- Egg Free Recipe - This cake is gluten-free (check your ingredients!), egg-free, and vegan.
- You Can Eat Protein Mug Cake for Breakfast - With around 25g of protein (or however much is in your favorite protein powder mix), you can feel good about microwaving this decadent chocolate cake and eating it as a filling breakfast.
- Cake in 5 Minutes! It takes about a minute to microwave the cake, and a couple of minutes to measure and mix the ingredients.
Tips and Tricks for Making The Best Protein Mug Cake
To ensure that your cake is gluten-free and/or vegan, you just need to make sure that your protein powder and other ingredients are that way! Use your favorite brand of protein powder that you already know meets your needs, or check the labels while you're shopping.
Any protein powder will work. Chocolate protein powder usually includes cocoa powder, so it works well in this recipe, but you can also use vanilla, coconut, or any other flavor you have. You can experiment with different brands if you like, as some will have a stronger "protein" flavor than others.
Know your microwave wattage. It takes 60-90 seconds to make a mug cake in a 1000-watt microwave but could take up to 2 minutes in a less powerful one. If your microwave is a higher wattage you may need less time.
Add Mix-Ins like peanut butter chips, shredded coconut, or walnuts if you like.
Add Frosting! Your favorite prepared frosting or a mini batch of vegan cream cheese frosting can be added to the cake after it's cooled down a bit.
If you want to make a mug cake without protein powder in it, check out my Vegan Chocolate Mug Cake recipe. It's very similar to this one! You might also like my Vegan Mug Brownie recipe, or this one I found for a keto mug cake.
Double, triple, or quadruple the recipe! If you'd like to make up a mix of the dry ingredients so that it's quicker to make the mug cake next time, feel free. More details are in the next paragraph!
Protein Powder Mug Cake Mix
The total amount of dry ingredients for one serving should be ⅓ cup, so you can multiply the dry ingredients in the recipe by any number, store the mixture in an airtight container, and then measure out ⅓ cup to make a single cake.
Mix ⅓ cup of the dry ingredient mixture with the listed wet ingredients and you're ready to go!
Be sure to mix the dry ingredients well before measuring, as they may settle during storage.
