• 1 cup sour cream
• 1 teaspoon vanilla extract

• 1/2 cup butter
• 4 cups powdered sugar

2. In a large bowl, cream together the butter and sugar until light and fluffy.
3. Beat in the eggs, one at a time, then stir in the sour cream and vanilla extract.

5. Fold in the mashed bananas.

For the Frosting:

1. In a medium saucepan, heat the butter over medium heat until boiling. Let the butter turn a delicate brown and remove from heat immediately.
2. Pour the butter into a bowl and add the powdered sugar, vanilla extract, and milk. Beat until smooth and creamy.
3. Spread the frosting over the cooled brownies before cutting into squares.
