Ingredients

Scale

Banana Bread Brownies

  • 2 eggs
  • 1 ½ cups white sugar
  • 1 cup regular sour cream
  • 1 stick unsalted butter (room temperature)
  • 3 large ripe bananas, mashed
  • 2 teaspoons pure vanilla extract
  • 1 teaspoon baking soda
  • 2 cups all-purpose flour
  • ¾ teaspoon kosher salt
  • 2 cups chopped pecans

Creamy Frosting

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

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 375°F (190°C). Spray a 9 x 13 inch baking pan with nonstick baking spray and line it with parchment paper for easy removal.
  2. Mix Wet Ingredients: In a large bowl, use an electric mixer to cream together the white sugar, sour cream, room temperature butter, and eggs until the mixture is smooth and well combined.
  3. Add Bananas and Vanilla: Stir the mashed ripe bananas and 2 teaspoons of vanilla extract into the wet mixture until fully incorporated.
  4. Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, and kosher salt.
  5. Combine Wet and Dry: Gradually add the dry ingredients to the wet ingredients, mixing gently until just combined. Avoid overmixing to keep the brownies moist and tender.
  6. Add Pecans: Fold in the chopped pecans evenly throughout the batter.
  7. Bake: Pour the brownie batter into the prepared pan and spread it out evenly. Bake in the preheated oven for 20 to 30 minutes, or until a toothpick inserted in the center comes out clean. Remove from oven and let cool completely in the pan.
  8. Brown the Butter: In a heavy skillet over medium heat, melt the ½ cup unsalted butter, cooking until it turns a light brown color and emits a nutty aroma, then transfer to a bowl and let it cool slightly.
  9. Make Frosting: Gradually add powdered sugar to the browned butter, stirring after each addition until smooth. Add the 1 ½ teaspoons vanilla extract and whole milk, then beat with an electric mixer until creamy and fluffy.
  10. Frost Brownies: Once the brownies have cooled completely, spread the creamy frosting evenly over the top.
  11. Serve: Cut the frosted banana bread brownies into bars and enjoy!

Notes

  • You can substitute thawed frozen bananas, but be sure to drain any excess liquid before mashing.
  • Feel free to omit the pecans or replace them with other nuts or chocolate chips according to your preference.
  • Store leftover brownies in an airtight container at room temperature for up to 3 days or refrigerate to extend freshness.
  • These brownies freeze well for up to 3 months; wrap tightly in plastic wrap and aluminum foil before freezing.
  • Alternate frostings such as chocolate ganache or cream cheese frosting can be used for variety.
