Description

Indulge in the delicious combination of moist banana bread brownies topped with a rich brown butter frosting. These treats are perfect for any occasion, from a sweet snack to a delightful dessert.


Ingredients

For the brownies:

  • 1/2 cup unsalted butter, softened
  • 1 cup granulated sugar
  • 1/2 cup sour cream
  • 2 large eggs
  • 2 ripe bananas, mashed (about 1 cup)
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt

For the brown butter frosting:

  • 1/2 cup unsalted butter
  • 2 cups powdered sugar
  • 2 tablespoons milk
  • 1/2 teaspoon vanilla extract

Instructions

  1. Preheat the oven and prepare the pan: Preheat the oven to 350°F (175°C) and grease a 9×13-inch baking pan.
  2. Mix the brownie batter: Cream butter and sugar, add sour cream, eggs, bananas, and vanilla. In a separate bowl, combine flour, baking soda, and salt. Mix wet and dry ingredients until just combined.
  3. Bake the brownies: Pour batter into the pan and bake for 25–30 minutes. Let it cool slightly.
  4. Prepare the brown butter frosting: Melt butter in a saucepan until golden brown, then mix in powdered sugar, milk, and vanilla until smooth.
  5. Frost the brownies: Spread warm frosting over the brownies. Allow to set before slicing and serving.

Notes

  • Enhance flavor with walnuts or cinnamon.
  • Frosting sets quickly, so spread it while warm.
  • Store leftovers in an airtight container at room temperature or in the fridge.
