Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter, plus more for greasing
  • 1 cup light brown sugar, packed
  • 1/2 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 1/2 cups all-purpose flour
  • 1/2 cup unsweetened cocoa powder
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking powder
  • 1 cup mashed very ripe bananas (about 2 large)
  • 1/2 cup chocolate chips (optional)
  • 1/2 cup (1 stick) unsalted butter for frosting
  • 2 cups powdered sugar, sifted
  • 2 tablespoons milk or cream
  • 1/4 teaspoon salt

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and line a 9×9 inch baking pan with parchment paper, leaving an overhang for easy removal.
  2. In a medium saucepan, melt 1/2 cup of butter over medium heat. Continue cooking, stirring occasionally, until the butter foams, then browns, and nutty brown bits form at the bottom. Remove from heat immediately and pour into a heatproof bowl to cool slightly. This is your brown butter.
  3. In a large bowl, whisk together the melted brown butter (including the browned bits), brown sugar, and granulated sugar until smooth.
  4. Whisk in the eggs one at a time, followed by the vanilla extract. Mix until just combined.
  5. In a separate bowl, whisk together the flour, cocoa powder, salt, and baking powder.
  6. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just incorporated. Do not overmix.
  7. Gently fold in the mashed bananas and chocolate chips, if using.
  8. Spread the batter evenly into the prepared baking pan.
  9. Bake for 30 to 35 minutes, or until a toothpick inserted near the center comes out with moist crumbs attached, not wet batter.
  10. Let the brownies cool completely in the pan on a wire rack.
  11. Prepare the Brown Butter Frosting: Melt the remaining 1/2 cup of butter and brown it as described in Step 2. Let it cool slightly.
  12. In a bowl, whisk the cooled brown butter with the powdered sugar, milk, and salt until smooth and creamy. Add more milk if the frosting is too thick.
  13. Once the brownies are completely cool, spread the brown butter frosting evenly over the top. Cut into squares and serve.

Notes

  • Use bananas that are heavily spotted or almost black for the best banana flavor and moisture in your banana bread brownies.
  • For a fudgier texture, slightly underbake the brownies by about 2 minutes.
  • If you prefer a chocolate swirl, reserve 1/4 cup of the batter and gently swirl 2 tablespoons of melted chocolate into the main batter before baking.
