Frosted Banana Bars

1/2 cup butter, room temperature
1 1/2 cup white sugar
2 eggs
1 cup sour cream
1 teaspoon vanilla
2 cups flour
1 teaspoon baking soda
1/4 teaspoon salt
1 cup mashed ripe bananas (about 3 large bananas)
cream cheese frosting

In a large bowl cream together butter and sugar.  Beat in eggs, once mixed add sour cream and vanilla.  Sift together the flour, baking soda and salt and then add to butter mixture.  Finally, mix in the mashed bananas.  Spread evenly in a greased 10x15 jelly roll pan (I used a 9x13 and baked them longer, more of a cake than a bar).

Bake at 350 degrees for 20-25 minutes or until a toothpick comes out clean.  Allow bars to cool completely then top with cream cheese frosting or some fresh whip cream and a drizzle of caramel sauce.
