Why You’ll Love These 3 Ingredient Banana Brownies

This isn’t just another brownie recipe; it’s a revolutionary approach to dessert. Here’s why you’ll find yourself making it again and again:

The Magic of Just Three Ingredients

The secret to these brownies lies in how three simple ingredients work together. The ripe bananas act as the sweetener and binding agent, providing moisture that eliminates the need for eggs or oil. The nut butter adds healthy fats and protein, creating that rich, fudgy texture. Finally, the unsweetened cocoa powder delivers that deep, decadent chocolate flavor you expect from a classic brownie. It’s a perfect culinary trifecta.

Prep Time 10 minutes
Cook Time 20 minutes
Total Time 30 minutes
Servings: 9 brownies
Course: Dessert, Snack
Cuisine: American
Calories: 110

Ingredients
  

  • 2 large ripe bananas Heavily spotted for maximum sweetness.
  • 1/2 cup creamy peanut butter Or any nut butter of your choice.
  • 1/4 cup unsweetened cocoa powder

Equipment

  • 1 8x8 inch baking pan
  • 1 Large Mixing Bowl
  • 1 Spatula

Method
 

  1. Preheat your oven to 350°F (175°C). Line an 8x8 inch baking pan with parchment paper, leaving some overhang to easily lift the brownies out later.
  2. In a large bowl, thoroughly mash the ripe bananas with a fork until they are mostly smooth with few lumps.
  3. Add the creamy peanut butter to the mashed bananas and stir until well combined and the mixture is uniform.
  4. Sift in the unsweetened cocoa powder. Gently fold it into the banana mixture until just combined. Be careful not to overmix.
  5. Pour the batter into the prepared baking pan and spread it evenly with a spatula.
  6. Bake for 18-20 minutes, or until a toothpick inserted into the center comes out with moist crumbs attached. Let the brownies cool completely in the pan before lifting them out and slicing into 9 squares.

Notes

For best results, use natural, creamy nut butter without added sugars.
Allow brownies to cool completely before cutting to ensure they hold their shape.
Feel free to stir in 1/2 cup of chocolate chips or chopped nuts for extra texture.

This recipe is designed for simplicity, but the results are anything but basic. The key is using very ripe, spotty bananas for the best flavor and sweetness.

Baker’s Tips for Perfect Fudgy Brownies

While this recipe is incredibly straightforward, a few expert tips can elevate your 3 ingredient banana brownies from great to absolutely unforgettable.

Choosing the Right Bananas

The riper, the better! Look for bananas with plenty of brown spots. They are sweeter and much easier to mash, creating a smoother, more uniform batter. This natural sweetness is crucial since we aren’t adding any other sugar.

Nut Butter Matters

A creamy, natural nut butter (like peanut, almond, or cashew) works best. Avoid brands with added sugars or oils, as they can alter the texture. The runnier the nut butter, the easier it will be to incorporate into the batter.

Don’t Overmix!

Once you add the cocoa powder, mix only until the ingredients are just combined. Overmixing can result in a tougher, denser brownie. We’re aiming for a light, fudgy texture, and gentle mixing is key to achieving that.

Fun Variations to Try

This recipe is a fantastic base for creativity. Feel free to add your own personal touch with these delicious mix-ins:

  • Chocolate Chips: Stir in a half cup of dark, semi-sweet, or milk chocolate chips for extra gooeyness.
  • Chopped Nuts: Add a handful of chopped walnuts or pecans for a delightful crunch.
  • Flaky Sea Salt: A sprinkle on top before baking perfectly balances the sweetness.
  • Protein Boost: Mix in a scoop of your favorite chocolate or vanilla protein powder. If you like this, you might also enjoy these mint chocolate chip protein balls (coming soon).
