Banana Bread Brownies

For the brownies:
1 1/2 C sugar
1 C sour cream
1/2 C unsalted butter, softened
2 eggs
3 1/2 - 4 ripe bananas, mashed (4 only if they're on the small side)
2 tsp vanilla extract
2 C all purpose flour
1 tsp baking powder
3/4 tsp salt
3/4 C chopped walnuts

For the frosting:
3/4 C unsalted butter
6 C powdered sugar
2 1/4 tsp vanilla extract
4 1/2 Tbsp milk, plus more if needed

Preheat oven to 375 degrees.  Grease 11x17 inch pan and set aside.

For the bars:
Beat together sugar, sour cream, butter and eggs in large bowl until creamy.  Blend in bananas and vanilla.  Add flour, baking powder, and salt and mix until just combined.  Fold in walnuts until evenly distributed.

Pour into prepared pan and bake 25-30 minutes or until knife inserted comes out clean. 

For the frosting:
When the bars only have about 15 minutes left, begin the frosting.  Place butter in large saucepan (pan needs to be big enough to hold all frosting ingredients), melt over medium heat and bring to a boil.  Allow butter to gently boil, scraping the bottom with a whisk every so often, until it turns a delicate brown color.  Remove from heat immediately.

*Keep an eye on the butter.  It will turn a light brown color after boiling for a few minutes, but will go from brown to burned fast if you're not careful. 

Add powdered sugar, vanilla and milk.  Whisk together.  If frosting is too thick add additional milk.
Spread frosting over warm bars.  Allow bars at least two hours to set before cutting and serving.
