Banana bars with brown butter frosting.

Easily the best thing I've ever baked (confirmed by several people). The original recipe--and the photo--came from this cute blog. The key is browning the butter just the right amount.  I can't believe I got t right on the first try. Bonus: I didn't start any fires.

Ingredients:

Banana Bread Bars:

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

Directions:

1.  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.

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). 

Yield: 2 dozen large bars
