Ingredients:

1-1/2 c. sugar

1 c. sour cream

1/2 c. butter, softened

2 eggs

1-3/4 (3 or 4) ripe bananas, mashed

2 tsp. vanilla extract

2 c. all purpose flour

1 tsp. baking soda

3/4 tsp. salt

1/2 c. chopped walnuts (optional)

1/2 c. butter (frosting)

4 c. powdered sugar (frosting)

1-1/2 tsp. vanilla extract (frosting)

3 tbsp. milk (frosting)

Directions:

1. Heat oven to 375F. Grease and flour 15x10-inch jelly roll pan.

2. For the bars, in a large bowl, beat together sugar, sour cream, butter, and eggs until creamy. Blend in bananas and vanilla extract. Add flour, baking soda, salt, and blend for 1 minute. Stir in walnuts. Spread batter evenly into pan.

3. Bake 20 to 25 minutes or until golden brown. Meanwhile, for frosting, heat butter in a large saucepan over medium heat until boiling. Let the butter turn a delicate brown and remove from heat

4. Add powdered sugar, vanilla extract and milk. Whisk together until smooth (it should be thicker than a glaze but thinner than frosting). Using a spatula, spread the brown butter frosting over the warm bars (the frosting will be easier to spread while the bars are still warm).

Bon Appetit!
