Key Ingredients for Protein Chocolate Peanut Butter Mug Cake
- 1 large egg
- 1/4 cup unsweetened almond milk (or milk of choice)
- 2 tablespoons protein powder (chocolate or peanut butter flavored recommended)
- 2 tablespoons all-purpose flour (or oat flour for gluten-free)
- 1 tablespoon unsweetened cocoa powder
- 1 tablespoon sugar (or your preferred sweetener, adjust to taste)
- 1 tablespoon creamy peanut butter (plus extra for topping, optional)
- 1/2 teaspoon baking powder
- Pinch of salt
- Optional: 1/4 teaspoon vanilla extract, sugar-free chocolate chips
How to Make Protein Chocolate Peanut Butter Mug Cake
This Protein Chocolate Peanut Butter Mug Cake is incredibly easy, taking less than 5 minutes to whip up, making it the ideal treat for busy days or sudden dessert urges. Expect a rich, decadent, and surprisingly moist cake with a comforting chocolate and peanut butter flavor explosion in every bite. This recipe requires no special equipment, just a mug and a microwave!
Step-by-Step Instructions
- Prepare Your Mug: Grab a microwave-safe mug (about 10-12 ounces is ideal). If you’re concerned about sticking, you can lightly grease the inside of the mug with a tiny bit of butter or cooking spray.
- Combine Wet Ingredients: Crack the large egg into the mug. Add the unsweetened almond milk and the vanilla extract (if using). Whisk these ingredients together directly in the mug with a fork until well combined and slightly frothy.
- Add Dry Ingredients (Part 1): To the same mug, add the protein powder, all-purpose flour (or oat flour), unsweetened cocoa powder, sugar (or sweetener), baking powder, and a pinch of salt. Stir these dry ingredients into the wet ingredients until just combined. Be careful not to overmix; a few small lumps are perfectly fine.
- Incorporate Peanut Butter: Spoon the creamy peanut butter into the center of the batter in the mug. You can gently swirl it in with your fork a little, or simply leave it as a pocket of peanut butter to be discovered when you take a bite.
- Optional Add-ins: If you’re adding sugar-free chocolate chips, now is the time to stir them into the batter.
- Microwave: Place the mug in the center of your microwave. Cook on high power for 60-90 seconds. The exact cooking time will vary depending on your microwave’s wattage. Start with 60 seconds and check for doneness. The cake should look set and a toothpick inserted into the center should come out mostly clean (a few moist crumbs are okay). If it’s still too wet, microwave in 10-second intervals until done.
- Cool and Enjoy: Carefully remove the hot mug from the microwave using oven mitts. Let the Protein Chocolate Peanut Butter Mug Cake cool for a minute or two before digging in. Top with an extra dollop of peanut butter, some whipped cream, a sprinkle of cocoa powder, or even a few fresh berries if desired!
