Why You’ll Love This Recipe

This recipe stands out for its simplicity and speed. With only four ingredients, it eliminates the need for complicated steps or hard-to-find items. It’s ideal for busy days when you want a quick dessert or a post-workout snack.

Another reason to love it is the texture. Despite being healthy, it achieves that dense, fudgy consistency you expect from a traditional brownie. There’s no dryness or chalky taste often associated with protein desserts.

It’s also naturally gluten-free and can easily fit into a balanced diet. Since it uses everyday ingredients, you likely already have everything you need in your kitchen.

Finally, the fact that it requires no protein powder makes it more accessible and appealing, especially if you prefer whole-food-based recipes.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

1 ripe banana (about 120 g), mashed until smooth
2 tablespoons unsweetened cocoa powder (12 g)
2 tablespoons natural peanut butter (32 g)
1 large egg

Directions

Start by selecting a ripe banana with brown spots, as this ensures natural sweetness and a smoother texture. Mash the banana thoroughly in a small bowl until no lumps remain.

Add the cocoa powder to the mashed banana and mix well until fully incorporated. The mixture should start to resemble a thick chocolate paste.

Next, stir in the peanut butter. Mix until the batter becomes smooth and glossy. Make sure the peanut butter is fully blended so there are no streaks.

Crack the egg into the mixture and whisk everything together until you have a uniform batter. The consistency should be thick but pourable.

Transfer the batter into a microwave-safe mug or small ramekin. Smooth the top with a spoon.

Microwave on high for about 90 seconds to 2 minutes, depending on your microwave’s power. The brownie should look set on top but still slightly soft in the center.

Allow it to cool for a minute before eating. This helps the texture firm up slightly and enhances the flavor.

Variations

You can easily customize this brownie to suit your taste. For a nuttier flavor, swap peanut butter with almond butter or cashew butter.

If you prefer a sweeter brownie, add 1 teaspoon of honey or maple syrup to the batter.

For a richer chocolate experience, mix in a tablespoon of dark chocolate chips before microwaving.

You can also enhance the flavor with a pinch of cinnamon or a few drops of vanilla extract.

For a dairy-free twist, ensure your chocolate add-ins (if used) are dairy-free as well.

Storage/Reheating

This brownie is best enjoyed fresh, right after cooking, when it’s warm and fudgy.

If you need to store it, cover and refrigerate for up to 24 hours. Keep in mind that the texture will become slightly firmer when chilled.

To reheat, microwave for 10–15 seconds to restore some of its softness. Avoid overheating, as it may dry out.
