How to Make Sour Cream Banana Bars With Brown Butter Frosting

  1. Preheat oven to 375°F (190°C). Grease and flour a 15 1/2 x 10 1/2 x 1-inch jelly roll pan.
  2. In a large bowl, cream together the sugar and softened butter until light and fluffy. Beat in the eggs one at a time, then stir in the sour cream and vanilla.
  3. In a separate bowl, whisk together the flour, baking soda, and salt.
  4. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
  5. Fold in the mashed bananas and nuts (if using).
  6. Spread the batter evenly into the prepared pan.
  7. Bake for 20-25 minutes, or until a wooden skewer inserted into the center comes out clean.
  8. Let the bars cool completely in the pan before frosting.
  9. While the bars are cooling, prepare the frosting: In a medium saucepan, melt the butter over medium heat. Cook, swirling the pan occasionally, until the butter turns a light brown color and has a nutty aroma (be careful not to burn it).
  10. Remove from heat and let cool slightly.
  11. Add the powdered sugar and vanilla extract to the browned butter. Whisk until smooth.
  12. Gradually add milk, 1 tablespoon at a time, whisking until the frosting reaches your desired consistency.
  13. Once the bars are completely cool, spread the frosting evenly over the top.
  14. Cut into 2 x 2-inch bars and serve.
