What You’ll Need

1 medium-sized banana, ripe (the riper, the sweeter!)
¼ cup (2 oz/57 g) peanut butter (or any nut butter of your choice)
1 large egg
3 tablespoons unsweetened cocoa powder
2 teaspoons granulated sugar (adjust to taste)

How to Make It

Mash the banana: In a small bowl, use a fork to mash the banana until smooth.
Mix in the wet ingredients: Add the nut butter and egg to the mashed banana. Stir thoroughly until well combined.
Add the dry ingredients: Stir in the cocoa powder and sugar. Mix until the batter is smooth and no lumps remain.
Divide the batter: Evenly divide the batter between two small microwave-safe mugs.
Microwave one at a time: Microwave the first mug for 45 seconds on high (1200 watts). Check the cake, then continue microwaving in 10-second increments until it’s risen and firm to the touch. Note: Cooking time may vary depending on your microwave’s wattage. Some microwaves may take up to 2 minutes, so check frequently to avoid overcooking.
Serve immediately: Enjoy your mug cake right away for the best texture. If making only one, cover the second mug with plastic wrap and refrigerate. Bake and eat within two days.

Topping Ideas to Elevate Your Mug Cake

Take your Chocolate Protein Mug Cake to the next level with these delicious toppings! Try a dollop of Greek yogurt for a creamy, protein-packed twist, or a drizzle of honey for a touch of natural sweetness.

For a decadent treat, sprinkle some crushed nuts or dark chocolate chips on top. If you’re feeling adventurous, a pinch of sea salt can enhance the chocolate flavor beautifully.

Quick Storage & Reheating Tips

If you’ve made an extra mug cake, cover it tightly with plastic wrap and store it in the refrigerator for up to two days. When you’re ready to enjoy, simply microwave it in 10-second increments until warm—be careful not to overheat, as it can dry out quickly. This cake is best enjoyed fresh, so try to reheat only when you’re ready to eat!

Easy Recipe Variations to Try

Swap out the peanut butter for almond or cashew butter to change up the flavor profile. If you’re looking for a vegan option, try using a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) instead of a regular egg. For a sweeter version, add a teaspoon of vanilla extract or a dash of cinnamon. Experiment and make it your own!

Microwave Wattage Tips for Perfect Cooking

Microwaves vary in power, so timing is crucial for this recipe. If your microwave is less than 1200 watts, start with 1 minute and check every 10 seconds until the cake is firm. For higher wattage microwaves, begin with 30 seconds and adjust as needed. It’s better to undercook slightly and add time than to risk drying it out. Keep an eye on it for the best results!
