Best Banana Bread Brownies (With Brown Butter Frosting): These cake-like banana bread bars seldom last long when I make them, so we savor every last bite. They are elevated to a remarkable level with just four basic ingredients—brown butter icing. I like to cut the bars into little squares for a quick after-school snack, but you can also personalize them by substituting chocolate chips or nuts for the frosting.

Instructions

For the brown butter frosting:Â
- In a large skillet over medium heat, melt the butter. Bring it to a simmer and let it get fragrant and start to turn a soft brown (be cautious not to burn the butter!). Take off the heat right away.
