Method
 

Step-by-Step Instructions
  1. Preheat your oven to 375°F (190°C) and prepare a greased or parchment-lined jelly roll pan.
  2. In a mixing bowl, cream together sugar, sour cream, and softened butter until smooth. Beat in eggs, then mash in bananas and vanilla until well combined.
  3. In another bowl, whisk together flour, baking soda, and salt. Gradually fold the dry mixture into the banana batter until just combined.
  4. Fold in the chopped walnuts if using, ensuring they're evenly distributed.
  5. Spread the batter evenly into the prepared pan and bake for 20-25 minutes or until a toothpick comes out clean.
  6. Allow the brownies to cool slightly in the pan before preparing the frosting.
  7. For the frosting, melt butter in a saucepan until browned, then whisk in powdered sugar, vanilla, and milk until smooth.
  8. Drizzle the frosting over the cooled brownies and allow to set before slicing.

Notes

Make sure your bananas are very ripe for the best flavor. Room temperature eggs help mix the batter smoothly. Chill brownies completely before cutting to prevent crumbling.
