Bars
1/2 cup butter, softened
1 1/2 cups white sugar
2 eggs
1 cup sour cream
1 teaspoon vanilla extract
2 cups all-purpose flour
1 teaspoon baking soda
1/4 teaspoon salt
1 cup mashed ripe banana
Preheat oven to 350F.  Grease a 9×13 inch pan.
In a large bowl, cream together the butter and the sugar until smooth.  Beat in the eggs, one at a time, then stir in the sour cream and vanilla.  In a separate bowl, combine the flour, baking soda and salt; stir into the wet batter.  Finally, mix in the mashed banana.  Spread evenly into the prepared pan.
Bake for 25 to 30 minutes, or until a toothpick inserted in the middle comes out clean.  Allow the bars to cool completely before frosting.
