Baking Instructions

• Heat your oven to 375°F and grease a 9x13 inch baking pan with butter or cooking spray.
• In a large mixing bowl, combine the softened butter, sugar, and sour cream, beating until light and fluffy for about 2-3 minutes.
• Add the eggs one at a time, beating well after each addition.
• Stir the mashed bananas and 2 teaspoon vanilla extract into the wet mixture until well combined.
• In a separate bowl, whisk together the flour, baking soda, salt, and cinnamon, then add to the banana mixture and mix gently.
• Fold in the chopped walnuts gently.
• Pour the batter into the prepared pan and bake for 20-25 minutes, until a toothpick comes out with a few moist crumbs.
• While baking, melt ½ cup butter in a saucepan and cook until browned, about 5-8 minutes.
• Remove from heat and whisk in powdered sugar, 1.5 teaspoon vanilla extract, and milk until smooth.
• Spread the warm frosting evenly over the warm brownies immediately after removing from the oven.
• Let cool completely at room temperature before cutting into squares.
