Ingredients
For the banana bars:
½cupunsalted butter, at room temperature (plus more for the pan)
Preheat the oven to 350°F. Butter a large rimmed baking sheet (12×18″). In a large bowl, cream together the butter, granulated sugar and brown sugar. Add the eggs, sour cream and vanilla. Mix just until combined.
In a separate bowl, whisk together the flour, baking soda, baking powder, salt and cinnamon. Slowly add the flour mixture into the other bowl and stir just until smooth. Fold in the mashed bananas and then pour into the baking sheet.
Bake for 20-25 minutes, or until a toothpick comes clean and the top is golden. Remove from oven and allow the bars to cool completely.
For the frosting:
For the brown butter frosting, melt the butter in a large sauce pan over medium heat. Cook for about 3-4 minutes, until the butter has turned a golden brown and has a nutty aroma. As soon as you notice the color change, quickly remove the pan from heat to prevent it from burning.
Whisk in the powdered sugar, milk and the vanilla. Pour immediately over the bars and spread evenly with a spatula. Move quickly, as the frosting will thicken fast. Cover until ready to serve.
