Ingredients You’ll Need

- Protein powder: Choose your favorite chocolate or vanilla protein powder to add that nutrient boost and structure.
- Peanut butter: Natural, creamy peanut butter enhances flavor and keeps the cake moist.
- Unsweetened cocoa powder: Adds deep chocolate richness without extra sugar.
- Baking powder: Makes the cake rise nicely, keeping it light and fluffy.
- Milk: Any kind works, dairy or plant-based, to bind everything together.

How to Make Protein Chocolate Peanut Butter Mug Cake Recipe
Step 1: Mix Dry Ingredients
Start by grabbing a medium bowl and combining your protein powder, cocoa powder, and baking powder. Sifting them together helps avoid lumps and ensures your mug cake will be smooth and airy.
Step 2: Add Wet Ingredients
In the same bowl, stir in the peanut butter, milk, sweetener, and egg until everything is just blended. The peanut butter melts slightly and mingles with the cocoa, creating a rich, inviting batter that’s ready to shine.
Step 3: Prepare Your Mug
Lightly grease your favorite microwave-safe mug with a bit of oil or non-stick spray. This simple step means your mug cake will come out clean and intact, making your dessert experience even more enjoyable.
Step 4: Cook Your Mug Cake
Pour the batter into the prepared mug, then microwave on high for 60 to 90 seconds. Keep an eye on it; microwave powers vary, but the cake is done when it has risen and springs back lightly when touched.
Step 5: Add Toppings and Enjoy!
Once cooked, feel free to top your Protein Chocolate Peanut Butter Mug Cake Recipe with any extras you like—maybe a dollop of Greek yogurt or a drizzle of melted peanut butter for that perfect finishing touch.
How to Serve Protein Chocolate Peanut Butter Mug Cake Recipe

Garnishes
Sprinkle chopped peanuts for crunch, or add a few fresh berries on top for a fruity contrast that brightens the chocolate and peanut butter flavors. A dusting of powdered sugar or a tiny scoop of vanilla ice cream also elevates this simple dessert to something special.
Side Dishes
Consider enjoying your mug cake alongside a warm latte or your favorite herbal tea to create a cozy experience. If you want a bit more substance, a small bowl of mixed nuts or fruit salad pairs beautifully without overpowering the rich cake.
Creative Ways to Present
Serve your mug cake in a clear glass mug to show off its layers or pile on colorful toppings like coconut flakes or dark chocolate shavings for a café-style dessert at home. You can even stir in some espresso powder before cooking for a hint of mocha flavor—talk about a grown-up treat!
Make Ahead and Storage
Storing Leftovers
While this Protein Chocolate Peanut Butter Mug Cake Recipe is best enjoyed fresh and warm, if you happen to have leftovers, cover your mug tightly with plastic wrap and refrigerate. It’ll be good for up to 2 days, though the texture may firm up slightly.
Freezing
If you want to prep in advance, you can freeze the batter in a small container (not the mug) for about a month. Thaw it overnight in the fridge, then microwave as usual for a quick, homemade dessert anytime.
Reheating
To reheat, pop the refrigerated mug cake back in the microwave for 20 to 30 seconds or until warm. Avoid overheating to keep it moist and tender—nobody wants a rubbery mug cake!
FAQs
Can I use any type of protein powder?
Absolutely! Whey, plant-based, or any flavor you prefer works well. Just keep in mind that unflavored protein powders might need a little extra sweetener.
Is it okay to substitute peanut butter with another nut butter?
Definitely. Almond butter, cashew butter, or even sunflower seed butter can be great alternatives and add their own unique taste.
What if I don’t have a microwave?
No worries! You can bake the batter in a small ramekin in a preheated oven at 350°F (175°C) for about 12-15 minutes, or until cooked through.
Can I make this recipe vegan?
Yes! Use a flax egg instead of a regular egg and plant-based milk. Just double-check your protein powder is also vegan-friendly.
How can I make the mug cake less dense?
Be careful not to overmix the batter and ensure your baking powder is fresh. Adding a splash more milk can also help lighten the texture.
