How to Make Banana Bread Brownies
Preparing the Brownies:
- Preheat the oven: Set your oven to 375°F (190°C). Line a 9×13-inch baking pan with parchment paper and coat it with nonstick spray.
- Mix wet ingredients: In a large mixing bowl, use an electric mixer to combine sugar, sour cream, softened butter, and eggs until smooth and creamy.
- Add bananas and vanilla: Stir in mashed bananas and vanilla extract until well blended.
- Incorporate dry ingredients: In a separate bowl, whisk together flour, baking soda, and salt. Gradually add to the wet ingredients, mixing just until combined.
- Add pecans: Fold in chopped pecans for added crunch (optional).
- Bake: Pour the batter into the prepared pan and spread evenly. Bake for 20–30 minutes or until a toothpick inserted in the center comes out clean. Let the brownies cool completely.
Making the Frosting:
- Brown the butter: Heat butter in a heavy skillet over medium heat until it turns golden brown and has a nutty aroma. Remove from heat.
- Mix frosting: In a bowl, combine browned butter with powdered sugar, adding it gradually while stirring. Add vanilla extract and milk, and blend with an electric mixer until smooth and creamy.
- Frost brownies: Spread the frosting over the cooled brownies in an even layer. Cut into squares or bars and serve.
