Ingredients You’ll Need
You only need a handful of simple ingredients to make these brownies:

- ½ teaspoon vanilla extract (optional, but recommended)
👉 Tip: Very ripe bananas with brown spots provide the best sweetness and moisture.
How to Make 3 Ingredient Banana Brownies
Step 1: Preheat and Prepare
Preheat your oven to 350°F. Line an 8×8-inch baking pan with parchment paper or lightly grease it. This ensures the brownies won’t stick and makes cleanup easy.
Step 2: Mix the Batter
In a large bowl, combine the mashed bananas, nut butter, cocoa powder, and vanilla extract. Stir well until the mixture is completely smooth and uniform in color. The batter should be thick but spreadable.
Step 3: Bake
Pour the batter into your prepared pan and spread it evenly into the corners using a spatula. Bake for 17–22 minutes, until the edges are set but the center still has a slight jiggle. For the fudgiest texture, aim for about 19–20 minutes.
Step 4: Cool and Slice
Remove the brownies from the oven and let them cool in the pan for at least 15 minutes. This helps them firm up and makes slicing much easier. Cut into squares and enjoy!
Tips & Variations
- Use creamy nut butter for the smoothest texture
- Almond or sunflower seed butter works if avoiding peanuts
- Add chocolate chips for extra richness (optional)
- Don’t overbake — a slightly soft center keeps them fudgy
- Chill before slicing for clean, bakery-style squares
Serving Ideas & Storage
Serve these brownies slightly warm or at room temperature. They pair perfectly with fresh fruit or a glass of cold milk.
Storage:
- Store in an airtight container at room temperature for 2 days
- Refrigerate for up to 5 days
- Freeze for up to 2 months and thaw before serving
