Banana Bars with Brown Butter Icing
Yield: 12 bars
  • ¾ cup sugar
  • ½ cup sour cream
  • ¼ cup butter, softened
  • 1 egg
  • 1 cup (about 2) very ripe bananas, mashed
  • 1 tsp. vanilla extract
  • 1 cup all purpose flour
  • ½ tsp. baking soda
  • ½ tsp. salt
  • brown butter frosting:
  • ¼ c. butter
  • 2 c. powdered sugar
  • 1 tsp. vanilla extract
  • 1½ tbsp. milk
  1. Heat oven to 375F. Line an 8x8 baking dish with parchment paper. (I overlap two pieces so the sides hang over the pan. It makes removing the bars easy as can be.)
  2. In a large bowl, beat together sugar, sour cream, butter, and eggs until creamy.
  3. Blend in bananas and vanilla extract.
  4. Add flour, baking soda, salt, stir together until just combined. Spread batter evenly into pan.
  5. Bake 20 to 25 minutes or until golden brown. Let cool slightly and then remove from pan using the parchment to lift.
Meanwhile, for frosting:
  1. Place butter in a heatproof dish with a well-fit dish on top. Microwave butter for 4-5 minutes. You will hear it bubble and pop and after wards it should be perfectly browned. Add powdered sugar, vanilla extract and milk. Whisk together until smooth and thick.
  2. Spread the icing on the bars when they have cooled for about 10-15 minutes. The frosting goes on much easier when the bars are a little warm, it also creates an amazing soft, slightly-melty affect.
