Banana Bread Brownies
Ingredients:
1-1/2 cups sugar
1 cup sour cream
1/2 cup butter, softened
2 eggs
1-3/4 cups ripe bananas, mashed (about 3 or 4 bananas)
2 teaspoons vanilla extract
2 cups all-purpose flour
1 teaspoon baking soda
3/4 teaspoon salt
1/2 cup chopped walnuts (optional)
Brown Butter Frosting:
1/2 cup butter
4 cups powdered sugar
1-1/2 teaspoons vanilla extract
3 tablespoons milk
Directions:
Preheat Your Oven and Prepare the Pan
Heat your oven to 375°F (190°C). Grease and flour a 15x10-inch jelly roll pan to ensure your brownies come out easily and have a lovely, golden finish.
Prepare the Brownie Batter
In a large bowl, beat together the sugar, sour cream, butter, and eggs until creamy. Blend in the mashed bananas and vanilla extract until well combined. Gradually add the flour, baking soda, and salt, mixing until just blended. If using, stir in the chopped walnuts.
Bake the Brownies
Spread the batter evenly into the prepared pan. Bake for 20 to 25 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
Make the Brown Butter Frosting
While the brownies are baking, prepare the frosting. In a large saucepan over medium heat, melt the butter, allowing it to cook until it turns a delicate brown color. Remove from heat immediately to prevent burning. Add the powdered sugar, vanilla extract, and milk, whisking until smooth. The consistency should be thicker than a glaze but thinner than traditional frosting.
Frost the Brownies
Once the brownies are baked and still warm, spread the brown butter frosting evenly over the top using a spatula. The frosting will spread more easily while the brownies are warm.
