Description

This delicious Banana Bread Brownies recipe combines the moistness of banana bread with the rich, chewy texture of brownies, topped with a luscious brown butter frosting for an indulgent treat that’s perfect for any occasion.

Ingredients

Batter

  • 1 1/2 cups sugar
  • 1 cup sour cream
  • 1/2 cup butter
  • 2 eggs
  • 4 ripe bananas, mashed
  • 2 teaspoons vanilla extract
  • 2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 3/4 teaspoon salt
  • 1/2 cup chopped walnuts

Brown Butter Frosting

  • 1/2 cup butter
  • 4 cups powdered sugar
  • 1 1/2 teaspoons vanilla extract
  • 3 tablespoons milk

Instructions

  1. Preheat Oven and Prepare Pan: Preheat your oven to 375°F (190°C). Grease and flour a 15×10-inch jelly roll pan to ensure your banana bread brownies don’t stick.
  2. Mix Wet Ingredients: In a large bowl, beat together the sugar, sour cream, butter, and eggs until the mixture becomes creamy and well combined, providing a smooth base for the batter.
  3. Add Bananas and Vanilla: Stir in the mashed ripe bananas and 2 teaspoons of vanilla extract, adding moisture and flavor to the batter.
  4. Combine Dry Ingredients: Gradually add the all-purpose flour, baking soda, and salt, mixing just until combined to avoid overworking the batter. Then gently fold in the chopped walnuts for added texture and nuttiness.
  5. Bake the Brownies: Spread the batter evenly in the prepared pan. Bake in the preheated oven for 20–25 minutes, or until the top is golden and a toothpick inserted into the center comes out clean.
  6. Prepare Brown Butter Frosting: While the brownies bake, brown the butter in a saucepan over medium heat until it turns golden and emits a nutty aroma. Remove from heat, then whisk in powdered sugar, vanilla extract, and milk until smooth and creamy.
  7. Frost and Cool: Once the brownies are out of the oven, spread the warm frosting evenly over the top. Allow the brownies to cool completely before cutting into 18 servings to ensure clean slices and a perfect texture.

Notes

  • Ensure bananas are very ripe for the best natural sweetness and moisture.
  • Do not over-mix the batter after adding flour to maintain a tender texture.
  • Brown butter carefully by monitoring heat to avoid burning, stirring frequently.
  • You can substitute walnuts with pecans or omit nuts entirely for a nut-free version.
  • Store leftovers in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
