Fudgy Banana Brownies Made with Ripe Bananas

These banana brownies are rich, fudgy, and intensely chocolatey with just the right hint of banana. Made with ripe bananas and melted chocolate, the batter comes together quickly and bakes into chewy brownies with a classic crackly top.

Why You Will Love These Banana Brownies

• Balanced banana flavor. Three ripe bananas add sweetness and moisture without turning these into banana bread.
• Fudgy, chewy texture. Whipped eggs provide lift while melted butter and chocolate keep the crumb dense and indulgent.
• No chemical leavening. These brownies rely on egg foam for structure, producing a classic crackly top.
• Flexible and scalable. Bake in a 9×13, mini muffin tins, or halve the batch for smaller gatherings.

If you have overripe bananas and want chocolate first, this recipe is perfect: banana-forward brownies that still read as brownies, not banana bread.

Ingredients & Substitutions

• Semi-Sweet Chocolate: Provides structure and richness. 55–65% dark chocolate works if you prefer a less sweet profile.
• Unsalted Butter: Adds flavor and contributes to a fudgy texture.
• Granulated Sugar: Dissolves into the egg foam and creates the crackly top. Replace up to half with brown sugar for a deeper caramel note.
• Whole Eggs: The sole leavening here—reaching the ribbon stage is essential.
• Ripe Bananas: Use fragrant, spotty bananas for the best flavor and moisture.
• Cocoa Powder: Dutch-processed cocoa provides a smooth, deep chocolate taste.
• All-Purpose Flour: Measure carefully to avoid cake-like brownies. For gluten-free, use equal weight oat flour for a slightly softer result.
• Chocolate Chips: Optional, but recommended for pockets of melty chocolate.

Banana Brownie Variations

• Add a frosting or glaze. Finish cooled brownies with cream cheese buttercream, chocolate fudge glaze, salted caramel buttercream, or a classic ganache.
• Make them Elvis-style. Fold in crispy bacon and swirl in peanut butter for a bold sweet-and-salty twist.
• Add a swirl. Nutella, nut butter, salted caramel, or cherry preserves make lovely additions.

Professional Tips

• Whip to the true ribbon stage. Eggs should triple in volume, lighten in color, and feel smooth—sugar should dissolve completely.
• Keep chocolate warm, not hot. Overheating can deflate the egg foam when combined.
• Use metal bakeware. Metal pans help the brownies rise evenly and develop the signature top.

How to Make Banana Brownies

Follow these steps for consistent results. Exact measurements are in the recipe card below.

Step 1: Preheat and prep. Preheat oven to 350°F. Spray and line a 9×13-inch metal pan with parchment, leaving an overhang for easy removal.

Step 2: Whisk dry ingredients. In a medium bowl, combine the flour, cocoa powder, and salt. Whisk until smooth and set aside.

Step 3: Prepare a bain-marie. Bring a small pot of water to a gentle simmer and set a heatproof bowl over it.

Step 4: Melt chocolate and butter. Combine chopped chocolate, butter, and vanilla in the heatproof bowl. Stir until just melted and smooth; remove from heat and let cool slightly.

Step 5: Whip eggs and sugar. In a stand mixer with the whisk attachment, beat eggs and sugar on high until pale, thick, and tripled in volume—the mixture should fall in ribbons and the sugar should be dissolved.

Step 6: Mash the bananas. Mash ripe bananas until mostly smooth; a few small lumps are fine. A large bowl helps keep the process tidy.

Step 7: Fold in chocolate and bananas. Pour the warm (not hot) melted chocolate into the whipped eggs and fold gently with a spatula until mostly combined, then fold in the mashed bananas.

Step 8: Add dry ingredients. Sift the flour mixture into the batter and fold gently just until incorporated—leave a few streaks of flour to avoid overmixing.

Step 9: Finish the batter. Fold in chocolate chips, pour the batter into the prepared pan, and smooth the top. Add extra chips if you like pockets of melted chocolate.

Step 10: Bake and cool. Bake 30–40 minutes until puffed, matte, and cracked on top. A tester should come out clean or with a few moist crumbs. Sprinkle with flaked sea salt and cool completely in the pan before slicing. Chill briefly in the fridge to speed slicing if desired.
