Description

These Banana Bread Brownies combine the moistness of banana bread with the rich indulgence of brownies, topped with a creamy, lightly caramelized butter frosting. Perfectly sweet and flavorful, they make a delightful dessert or snack that serves 16 and boasts a wonderfully tender crumb.


Ingredients

Scale

For the Brownies:

  • 2 eggs
  • 3 bananas, mashed
  • 1 ½ cups sugar
  • 1 cup sour cream
  • ½ cup butter, softened
  • 2 teaspoons vanilla extract
  • 2 cups all-purpose flour
  • 1 teaspoon baking soda
  • ¾ teaspoon salt
  • ½ cup walnuts, chopped (optional)

For the Frosting:

  • ½ cup butter
  • 3 cups powdered sugar
  • 1 ½ teaspoons vanilla extract
  • 3 tablespoons milk


Instructions

  1. Preheat the Oven: Preheat your oven to 375°F (190°C) and grease a 13 x 9 inch baking pan thoroughly to ensure the brownies do not stick.
  2. Mix the Wet Ingredients: In a large bowl, beat together the sugar, sour cream, softened butter, and eggs until the mixture becomes smooth and creamy, creating a rich base for the batter.
  3. Add the Bananas and Vanilla: Fold in the mashed bananas and vanilla extract gently to incorporate the natural sweetness and flavor without overmixing.
  4. Incorporate the Dry Ingredients: Gradually mix in the all-purpose flour, baking soda, and salt until just combined, ensuring a uniform batter without overworking it.
  5. Add the Walnuts: Stir in the chopped walnuts if desired, adding a crunchy texture to the brownies.
  6. Bake: Pour the batter evenly into the prepared pan and bake for approximately 25 minutes, or until golden brown and a toothpick inserted into the center comes out clean.
  7. Prepare the Frosting: While the brownies are baking, heat the butter in a saucepan over medium heat until it reaches a medium brown color, giving a rich, nutty flavor to the frosting.
  8. Finish the Frosting: Remove the browned butter from heat and whisk in the powdered sugar and milk until the mixture is smooth. Stir in the vanilla extract for added aroma and sweetness.
  9. Frost and Cool: Pour the warm frosting evenly over the freshly baked brownies and spread smoothly. Allow the brownies to cool completely in the pan before cutting into 16 squares.

Notes

  • You can omit walnuts if you prefer nut-free brownies.
  • Ensure bananas are very ripe for optimal sweetness and moisture.
  • Do not overmix the batter to avoid tough brownies.
  • Allow the brownies to cool completely before slicing to maintain clean cuts.
  • The browned butter frosting adds a rich, caramel-like flavor, but can be substituted with a simple vanilla glaze if preferred.
