Instructions
Brownies
- Preheat an oven to 375°F and prepare a 9 X 13 pan by spraying with baking spray or lightly greasing.
- Combine the butter, white sugar, and brown sugar in a large bowl and mix until well combined.1/2 cup salted butter, 3/4 cup granulated white sugar, 3/4 cup light brown sugar
- Add the eggs, one at a time, mixing well between additions. Scrape the bowl as needed.2 large eggs
- Add the vanilla and sour cream and beat until completely combined.1 tablespoon vanilla extract, 1 cup sour cream
- Add the flour and baking soda and mix just until the flour is incorporated.2 cups all purpose flour, 1 teaspoon baking soda
- Add the bananas and mix until smooth.1 3/4 cups mashed bananas
- Pour the batter into the prepared pan and bake for 25 to 30 minutes or until a toothpick inserted into the center of the brownies comes out clean.
- During the last 5 minutes of baking, prepare the frosting.
Frosting
- Place the butter into a medium sauce pan and set the heat to medium-high. Heat the butter until it starts to bubble, stirring frequently until the butter has turned a medium to dark blonde color, about 2 to 3 minutes. Remove from the heat.1/2 cup butter
- Add the powdered sugar and mix to combine, add the vanilla and milk and stir until smooth and creamy.1/4 cup milk, 2 teaspoons vanilla extract, 4 cups confectioners sugar
- Add more milk if the frosting is too thick.
- Top the brownies with the frosting while the brownies and frosting are both still warm, this will make spreading out the frosting easier.
Notes
- If the frosting is done before the brownies are, move the frosting back to the still-warm burner to keep it soft for longer. It can also be held on a "keep warm" setting if your stove has one.
- Work quickly when frosting the brownies, otherwise the frosting will start to form a skin as it cools.
