Method
Preparation
- Preheat the oven to 375°F (190°C) and grease a 13 x 9-inch baking pan.
- In a large bowl, beat together sugar, sour cream, butter, and eggs until creamy.
- Stir in the mashed bananas and vanilla extract until well combined.
- Add flour, baking soda, and salt, then blend the mixture for 1 minute.
- Gently fold in the chopped walnuts.
- Spread the batter into the prepared pan and smooth the top.
Baking
- Bake for 25 minutes or until golden brown and a toothpick inserted in the center comes out clean. Let cool slightly before frosting.
Frosting
- Melt butter over medium heat in a saucepan, heating until golden brown.
- Whisk in powdered sugar, followed by milk one tablespoon at a time until smooth.
- Stir in vanilla.
- Pour the frosting over the warm brownies, smoothing it with a spatula. Allow to cool completely before cutting into squares.
Notes
Pro Tips: Let the brownies cool properly to ensure the frosting sets beautifully. Use riper bananas for sweeter brownies. Bring eggs and butter to room temperature for a smoother batter.
