What you will need
This recipe uses 6 simple ingredients that you can find at any grocery store:
- 1 scoop chocolate protein powder
- 2 tablespoons unsweetened cocoa powder
- 1 tablespoon natural peanut butter
- 1 whole large egg
- 3 tablespoons unsweetened almond milk
- 0.5 teaspoon baking powder
Step by step instructions
Step 1: Mix the Batter
In a large microwave-safe mug combine the chocolate protein powder cocoa powder and baking powder and stir with a fork to combine the dry ingredients.
Step 2: Add Wet Ingredients
Add the egg almond milk and natural peanut butter to the mug. Stir vigorously until the batter is completely smooth with no lumps visible. Scrape the sides and bottom of the mug to ensure everything is incorporated.
Step 3: Microwave the Cake
Microwave the mug on high power for 60 to 90 seconds depending on your microwave wattage. The cake is done when the center is just set and slightly moist. Do not overcook it or the texture will become rubbery.
Step 4: Cool and Serve
Allow the mug cake to cool for one minute before eating as it will be very hot immediately after cooking. Eat directly from the mug with a spoon and enjoy as is or top with a drizzle of extra peanut butter.
Easy substitutions
Missing an ingredient? Here are some swaps that work perfectly:
- chocolate protein powder → vanilla protein powder for a lighter flavor that pairs well with the peanut butter
- unsweetened almond milk → regular milk or oat milk for a creamier texture and slightly higher carb content
Common mistakes to avoid
Watch out for these pitfalls that can affect your results:
- Overcooking the mug cake which turns the texture dry rubbery and unpleasant
- Not mixing the batter thoroughly enough which results in pockets of dry protein powder in the finished cake
