Scale
For the Banana Bread Brownies:
- 1 ½ cups sugar
- 1 cup sour cream
- ½ cup (1 stick) unsalted butter, at room temperature
- 2 eggs, at room temperature
- 3 bananas, mashed
- 2 teaspoons vanilla extract
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- ¾ teaspoon salt
- ½ cup walnuts, chopped
For the Brown Butter Frosting:
- ½ cup unsalted butter
- 3 cups powdered sugar
- 1 ½ teaspoons vanilla extract
- 3 tablespoons milk
Instructions
- Prepare Your Workspace: Preheat your oven to 375°F and grease a 9x13 inch baking pan with non-stick cooking spray.
- Create the Base: In a large mixing bowl, combine sugar, sour cream, softened butter, and eggs. Beat with an electric mixer until smooth and well incorporated.
- Add Banana Mixture: Fold in the mashed bananas and vanilla extract until evenly distributed throughout the batter.
- Incorporate Dry Ingredients: Gradually add the flour, baking soda, and salt to the wet ingredients, mixing until just combined. Gently fold in the chopped walnuts.
- Bake to Perfection: Pour the batter into your prepared pan, spreading it evenly. Bake for 20-30 minutes, or until a toothpick inserted into the center comes out clean.
- Prepare the Frosting: While the brownies cool, brown the butter in a saucepan until it reaches a medium amber color. Remove from heat and gradually stir in the powdered sugar, followed by milk and vanilla extract.
- Finish and Serve: Once the brownies have cooled slightly, spread the warm frosting evenly over the top. Allow to cool completely before cutting into squares.
