Method §

1. Preheat your oven to 350F and line a 9x13 inch baking pan with parchment paper.
2. In a medium saucepan, melt the unsalted butter over medium heat. Once melted, continue to cook, stirring occasionally, until the butter turns a deep golden brown color. This should take about 5 minutes. Remove from heat and let cool for a few minutes.
3. In a large bowl, whisk together the granulated sugar, light brown sugar, and eggs until smooth.
4. Add the sour cream, mashed banana, vanilla extract, and baking soda to the bowl and whisk until well combined.
5. Slowly pour in the cooled brown butter while whisking constantly. Make sure to scrape the bottom of the pan to get all of the brown bits.
6. Add the kosher salt and all purpose flour to the bowl and mix until just combined.
7. Pour the batter into the prepared baking pan and smooth out the top with a spatula.
8. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean. Let cool completely before frosting.
9. To make the frosting, melt the unsalted butter in a medium saucepan over medium heat. Continue to cook, stirring occasionally, until the butter turns a deep golden brown color. Remove from heat and let cool for a few minutes.
10. In a large bowl, whisk together the cooled brown butter, powdered sugar, vanilla extract, and milk until smooth.
11. Pour the frosting over the cooled banana bread bars and spread it out evenly with a spatula.
