You’ll need:

For the Brownies

• 2 cups all-purpose flour
• 1 teaspoon baking powder
• 1 teaspoon baking soda
• 1 teaspoon cinnamon
• ½ teaspoon salt
• ½ cup of unsalted butter, softened
• ½ cup light brown sugar, packed
• ½ cup granulated sugar
• 2 large eggs
• 3 ripe medium bananas, mashed (about 1 cup)
• ¾ cup buttermilk
• 1 tablespoon vanilla extract
• ¾ cup chopped walnuts

For the Frosting

• ⅓ cup of unsalted butter
• 2½ cups powdered sugar
• ¼ cup half-and-half cream
• 2 teaspoons vanilla extract

PRO TIP:

If you don’t want to wait for the perfect window when your bananas are perfectly ripe for baking, you can follow these instructions. To ripen bananas in the oven, bake them on parchment paper on a baking sheet at 300°F for 30-40 minutes until they are darkly blackened and soft to the touch. You can also speed up the cooling process by opening them and gently mashing them in a big bowl to help heat escape more quickly. Be sure to let them cool before adding to your batter. 

Substitutions And Additions

NUTS: This banana bread brownie recipe will work fine if you want to leave out the nuts because of allergies or if you simply are not a fan of nuts.

CHOCOLATE CHIPS: Mini chocolate chips make a great addition if you love chocolate. Add ¾ cup instead of the walnuts or in addition to the walnuts.

How To Make This Banana Bread Brownies Recipe

For The Brownies

STEP ONE: Preheat the oven to 350°F. Spray a 9×13-inch baking pan with non-stick cooking spray. Set aside.

STEP TWO: In a medium bowl, whisk together the flour, baking powder, baking soda, cinnamon, and salt. Set the dry ingredients aside.

STEP THREE: In a large bowl, with an electric mixer, cream together the butter, brown sugar, and granulated sugar until combined and fluffy.

STEP FOUR: Add the eggs, mashed bananas, buttermilk, and vanilla and mix well.

STEP FIVE: Gradually add the flour mixture to the banana mixture, mixing until well combined.

STEP SIX: Stir in the chopped walnuts.

STEP SEVEN: Pour the brownie banana bread batter into the prepared pan and bake for 20 minutes, until the edges are golden, and a toothpick inserted in the center comes out with just a few crumbs.

For The Brown Butter Frosting

STEP ONE: In a small saucepan, over medium heat, melt the butter and cook until it is a golden brown color and has a nutty aroma. Immediately, remove from the heat and stir in the powdered sugar, half and half cream, and vanilla.

STEP TWO: Using a silicone or rubber spatula, spread the frosting over the warm banana brownies.

How To Serve

These warm bars would be a delicious dessert or afternoon snack. If you are looking for an even more indulgent treat, they would be delicious with a scoop of vanilla ice cream and whipped cream on top. Of course, no dessert is complete without a drizzle of hot fudge sauce or caramel sauce.

• These banana bread brownies are moist and dense. If you prefer a more cake-like texture, bake them for 25 minutes or until there are no crumbs when you test with a toothpick.
• Start making the frosting when you remove the banana bread brownies from the oven so that they will be warm but not too hot when you frost them.
