Step-by-Step Instructions
- Preheat your oven to 375°F (190°C) and prepare your 15x10-inch jelly roll pan by greasing or lining it with parchment paper.
- In a large mixing bowl, beat together the sugar, sour cream, softened butter, and eggs until creamy and well-combined (about 2-3 minutes).
- Gently stir in the ripe mashed bananas and vanilla extract until fully integrated.
- Mix in the all-purpose flour, baking soda, and salt until just blended; fold in walnuts if using.
- Pour the batter into the prepared pan and bake for 20-25 minutes until lightly golden at the edges.
- Melt the butter in a saucepan over medium heat until golden brown and nutty (5-7 minutes).
- Whisk in the powdered sugar, vanilla extract, and milk until smooth and creamy.
- Spread the frosting generously over the freshly baked brownies and let them cool in the pan.
- Once cooled, slice the brownies into squares for serving.

Notes
Ensure your bananas are very ripe for the best results. Avoid overbaking for chewy brownies. Frosting consistency can be adjusted by adding milk gradually.
