Ingredients:

For the Brownies:

  • 1 cup (200 g) granulated sugar
  • 1 cup (240 ml) sour cream (or plain Greek yogurt)
  • ½ cup (113 g) unsalted butter, softened
  • 2 large eggs
  • 4 ripe bananas (mashed, about 2 cups)
  • 2 teaspoons pure vanilla extract
  • 2 cups (250 g) all-purpose flour
  • 1 teaspoon baking soda
  • ¾ teaspoon salt
  • ½ cup (60 g) chopped walnuts (optional)

For the Frosting:

  • ½ cup (113 g) unsalted butter
  • 4 cups (480 g) powdered sugar
  • 1½ teaspoons pure vanilla extract
  • 3 tablespoons milk (more if needed for spreading)

Directions:

Prepare the Pan:
Preheat oven to 350°F (175°C). Grease and flour a 9×13-inch baking dish or line with parchment paper.

Make the Banana Brownie Batter:
In a large mixing bowl, cream together sugar, sour cream, and softened butter until light and fluffy. Beat in eggs, mashed bananas, and vanilla extract until smooth. In a separate bowl, whisk together flour, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, mixing just until combined. Fold in walnuts, if using.

Bake:
Pour the batter into the prepared pan and spread it evenly. Bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean. Let cool in the pan on a wire rack.

Prepare the Frosting:
In a small saucepan, melt butter over medium heat and cook until it turns a light golden brown and smells nutty (about 4–5 minutes). Remove from heat and let cool slightly. Whisk in powdered sugar, vanilla, and milk until smooth and spreadable.

Frost and Serve:
Spread frosting over the cooled brownies. Cut into squares or bars and serve.

tips to make Banana Bread Brownies

  1. Use overripe bananas: The riper the bananas, the sweeter and more flavorful the brownies will be.
  2. Mix gently: When combining the wet and dry ingredients, mix just until combined. Overmixing can make the brownies dense.
  3. Watch the baking time: Keep an eye on them as they bake. Ovens can vary, so start checking a few minutes before the minimum baking time.
