Sour Cream Banana Bars

I LOVE these! This recipe is my mom's, and they are the greatest!! They freeze really well too, and I also love them right out of the freezer.

1 1/2 cups sugar
1 cup sour cream
1/2 cup butter or margarine, softened
2 eggs
1 1/2 cups mashed bananas (about 3 large)
2 tsp vanilla
2 cups flour
1 tsp baking soda
3/4 tsp salt
1/2 cup chopped nuts

Heat oven to 375 degrees. Grease and flour jelly roll pan (15 1/2 X 10 1/2). Mix sugar, sour cream, butter, and eggs in a large bowl on low speed for 1 minute. Beat in bananas and vanilla on low speed for 30 seconds. Beat in flour, baking soda and salt on medium speed for 1 minute. Stir in nuts. Spread in pan. Bake until light brown, 20 to 25 minutes. Cool. Frost with browned butter frosting. Makes 48 bars.
