Ingredients
For the brownies:
2 eggs
3 ripe mashed bananas
1 1/2 cups sugar
1 cup sour cream
1/2 cup softened butter
2 teaspoons vanilla extract
2 cups all purpose flour
1 teaspoon baking soda
3/4 teaspoons salt
1/2 cup chopped walnuts
For the frosting:
1/2 cup butter
3 cups powdered sugar
1 1/2 teaspoons vanilla
3 Tablespoons milk
Instructions:
Preheat oven to 375 degrees. Grease a 9x13 inch pan.
In a mixing bowl, combine sugar, butter, sour cream and eggs. Beat until well combined.
Blend in bananas and vanilla.
Add flour, baking soda and salt and mix until just blended (about one minute).
Spread batter in prepared pan. Bake for 25 minutes or until toothpick inserted in the middle comes out clean.
Frost while still warm.
To make the frosting, heat butter in saucepan over medium-low heat. Watch carefully and remove from heat when the butter is just beginning to brown. Be careful or the butter will burn.
Add confectioner's sugar, vanilla and milk and stir vigorously until combined and smooth. Spread over warm brownies.
Top with additional chopped walnuts, if desired.
