Banana Bread Brownies
Ultra-moist, rich, and perfectly chewy — the best of banana bread and brownies in one irresistible pan.

Why You’ll Love These Banana Bread Brownies

If banana bread and brownies had a dessert baby, this would be it. These Banana Bread Brownies are soft and fudgy like a brownie, yet tender and fragrant like classic banana bread. They’re packed with ripe banana flavor, deep chocolate richness, and finished with a delicate crackly top that makes every bite feel bakery-worthy.

This recipe is:

  • Perfect for using overripe bananas

  • Simple and one-bowl friendly

  • Great for snacks, bake sales, or dessert

  • Easy to customize with chocolate chips, nuts, or swirls

Whether you cut them into thick squares or thin bars, these brownies disappear fast — so you may want to make a double batch.

Banana Bread vs. Banana Bread Brownies

Traditional banana bread is light, fluffy, and sliceable. Brownies are dense, fudgy, and rich.
Banana Bread Brownies sit right in the middle:

  • More moist and dense than banana bread

  • Softer and more cake-like than classic brownies

  • Strong banana flavor balanced with chocolate sweetness

They’re baked in a square pan, sliced like brownies, and eaten like a treat you’ll crave again and again.

Ingredients You’ll Need

Banana Bread Brownie Batter

  • 2 large very ripe bananas, mashed (about 1 cup)

  • ½ cup unsalted butter, melted and slightly cooled

  • ¾ cup brown sugar, packed

  • ¼ cup granulated sugar

  • 1 large egg, room temperature

  • 1 teaspoon vanilla extract

  • 1 cup all-purpose flour

  • ¼ cup unsweetened cocoa powder

  • ½ teaspoon baking soda

  • ¼ teaspoon salt

  • ½ cup semi-sweet chocolate chips (optional but recommended)

Optional Toppings or Mix-Ins

  • Chopped walnuts or pecans

  • Extra chocolate chips for sprinkling

  • Peanut butter swirl

  • Nutella drizzle

  • Banana slices (add after baking)

Kitchen Tools

  • Mixing bowl

  • Whisk or wooden spoon

  • 8×8-inch (20×20 cm) baking pan

  • Parchment paper

  • Spatula

Step-by-Step Instructions

Step 1: Prepare the Pan

Preheat your oven to 350°F (175°C).
Line an 8×8-inch baking pan with parchment paper, leaving a slight overhang for easy removal. Lightly grease if needed.

Step 2: Mash the Bananas

In a large bowl, mash the ripe bananas until mostly smooth. Small lumps are fine — they add texture and bursts of banana flavor.

Step 3: Add Wet Ingredients

Whisk the melted butter into the mashed bananas until combined.
Add brown sugar and granulated sugar and mix until glossy.

Whisk in:

  • Egg

  • Vanilla extract

The mixture should look thick, smooth, and slightly shiny.

Step 4: Mix the Dry Ingredients

In the same bowl (or a separate one), add:

  • Flour

  • Cocoa powder

  • Baking soda

  • Salt

Gently fold until just combined. Do not overmix — this keeps the brownies tender.

Step 5: Fold in Chocolate Chips

Stir in the chocolate chips or any add-ins you’re using. The batter will be thick and rich.

Step 6: Bake

Spread the batter evenly into the prepared pan.

Bake for 22–28 minutes, or until:

  • The top looks set

  • A toothpick inserted comes out with a few moist crumbs (not wet batter)

Avoid overbaking — these brownies are best when soft and fudgy.

Step 7: Cool and Slice

Let the brownies cool in the pan for at least 20 minutes, then lift out using the parchment paper.

Slice into squares or bars and enjoy.

Texture and Flavor Notes

  • Ultra-moist interior thanks to bananas and brown sugar

  • Deep chocolate flavor without overpowering the banana

  • Soft edges, tender center, and a slightly crackly top

  • Even better the next day once flavors settle

Tips for Perfect Banana Bread Brownies

  • Use very ripe bananas — the darker the peel, the sweeter and better the flavor

  • Don’t overbake — pull them while the center is still soft

  • Cool melted butter slightly before mixing to avoid cooking the egg

  • Measure flour correctly — spoon and level, don’t pack

  • For clean cuts, wipe your knife between slices
