Banana Bread Bars Recipe

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)  

Brown Butter Frosting:  

1/2 c. butter

4 c. powdered sugar

1-1/2 tsp. vanilla extract

3 tbsp. milk

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

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 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).
