How to Make Sour Cream Banana Bars

Preheat oven to 375°F (190°C). Grease and flour a 15x10x1 inch jelly roll pan (or 9x13 inch pan for thicker bars).
In a large bowl, cream together 1 cup (2 sticks) softened butter and 1 ¾ cups granulated sugar until light and fluffy.
Beat in 1 cup sour cream and 2 large eggs until well combined.
Mash 3 ripe bananas and add them to the wet ingredients along with 1 teaspoon vanilla extract. Mix well.
In a separate bowl, whisk together 2 ½ cups all-purpose flour, 1 teaspoon baking soda, and ½ teaspoon salt.
Gradually add the dry ingredients to the wet ingredients, mixing on medium speed until just combined. Be careful not to overmix.
Stir in ½ cup chopped walnuts or pecans (optional).
Pour batter into the prepared pan and spread evenly.
Bake for 20-25 minutes (or 25-30 minutes for a 9x13 inch pan), or until a wooden skewer inserted into the center comes out clean.
Let cool completely in the pan before frosting with your favorite brown butter frosting.
