Description

A delightful twist on classic banana bread, these brownies topped with brown butter frosting are perfect for fall gatherings.


Ingredients

Scale
  • 1½ cups sugar
  • 1 cup sour cream
  • ½ cup butter, softened
  • 1¾ cups ripe bananas (about 3 large bananas)
  • 2 tsp vanilla extract
  • 2 cups all-purpose flour
  • 1 tsp baking soda
  • ¾ tsp salt
  • ½ cup chopped walnuts (optional)
  • ½ cup butter (for frosting)
  • 4 cups powdered sugar
  • 1½ tsp vanilla extract (for frosting)
  • 3 Tbsp milk

Instructions

  1. Preheat oven to 375°F (190°C). Grease and flour a 15×10″ pan.
  2. In a large bowl, beat together the sugar, sour cream, butter, and eggs until creamy and well combined.
  3. Mix in the mashed bananas and vanilla extract, blending until smooth.
  4. Add in the flour, baking soda, and salt. Blend well till there are no dry ingredients left. Stir in walnuts if using.
  5. Pour the batter into your prepared pan and bake for 20–25 minutes, or until the top is golden and a toothpick inserted comes out clean.
  6. For the frosting, brown the butter in a saucepan over medium heat until golden. Remove from heat and let it cool slightly.
  7. Stir in powdered sugar, vanilla extract, and milk until smooth.
  8. Spread the brown butter frosting over the warm bars, allowing it to melt into the bars.
  9. Allow the bars to cool, slice into squares, and enjoy!
