Ingredients

Scale

For the Brownies:

  • ½ cup (1 stick) unsalted butter, melted
  • 1 cup granulated sugar
  • ½ cup light brown sugar, packed
  • 2 large eggs
  • 1 tsp vanilla extract
  • 2 ripe bananas, mashed (about 1 cup)
  • 1 cup all-purpose flour
  • ½ tsp baking powder
  • ¼ tsp baking soda
  • ½ tsp salt
  • ½ tsp ground cinnamon (optional)
  • ½ cup chopped walnuts or pecans (optional)

For the Glaze/Frosting:

  • ¼ cup unsalted butter
  • 1 cup powdered sugar
  • 2 tbsp milk or heavy cream
  • ½ tsp vanilla extract

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C) and grease or line a 9×9-inch baking pan to prevent sticking.
  2. Make the Brownie Batter: In a large bowl, whisk together the melted butter, granulated sugar, and brown sugar until smooth. Beat in the eggs and vanilla extract until fully incorporated. Stir in the mashed bananas, then add the flour, baking powder, baking soda, salt, and cinnamon, mixing just until combined to avoid overmixing. Fold in the chopped nuts if desired.
  3. Bake the Brownies: Spread the batter evenly into the prepared pan. Bake in the preheated oven for 25–30 minutes, or until a toothpick inserted into the center comes out clean. Allow them to cool slightly while you prepare the glaze.
  4. Prepare the Glaze: In a small saucepan, melt the butter over medium heat, cooking it until it becomes golden brown, about 3 to 4 minutes. Remove from heat and whisk in the powdered sugar, milk (or heavy cream), and vanilla extract until the glaze is smooth and creamy.
  5. Glaze and Cool: Pour the warm glaze evenly over the brownies. Let the brownies cool completely before slicing into squares to ensure the glaze sets properly.

Notes

  • Use very ripe bananas for the best flavor and natural sweetness.
  • Do not overmix the batter to keep the brownies moist and tender.
  • The cinnamon in the batter is optional but adds a nice warmth to the flavor.
  • Walnuts or pecans add texture but can be omitted for nut-free brownies.
  • Allow brownies to cool completely before glazing if you prefer a thicker glaze layer.
