INGREDIENTS
- 1-1/2 c sugar
- 1 c sour cream
- 1/2 c butter
- 2 eggs
- 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
BROWN BUTTER FROSTING
- 1/2 c butter
- 4 c powdered sugar
- 1 1/2 tsp vanilla extract
- 3 Tbsp milk
DIRECTIONS
1. Heat oven to 375F. Grease and flour 15×10-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.
2. Spread batter evenly into pan. Bake 20 to 25 minutes or until golden brown.
3. 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 immediately.
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).
