How to Make Banana Bread Brownies
- Preheat your oven to 350°F (175°C) and take a 9×13-inch baking pan. Either line it with parchment paper or lightly grease the bottom and sides for easy removal.
- Mash the ripe bananas in a mixing bowl until the mixture is smooth and creamy; set them aside to be blended later.
- Cream together the melted unsalted butter, granulated sugar, and brown sugar in a large mixing bowl until the mixture is fluffy and well combined.
- Incorporate the eggs one at a time, mixing them well after each addition. Then stir in the sour cream and vanilla extract, followed by the mashed bananas until everything is nicely blended.
- Whisk together the all-purpose flour, baking soda, and salt in a separate bowl. Slowly blend this dry mixture into your wet ingredients until just combined—remember, don’t overmix!
- Pour the brownie batter into the prepared baking pan, spreading it evenly with a spatula. Bake for 28 to 32 minutes, or until a toothpick comes out clean with a few moist crumbs attached.
- Cool the brownies completely in the pan before adding the frosting for the best results.
- Brown your 1/4 cup of unsalted butter in a saucepan over medium heat, stirring frequently until it becomes golden and emits a nutty aroma (about 5-7 minutes).
- Remove from heat and whisk in the powdered sugar, vanilla extract, and 1 tablespoon of milk. Add more milk gradually until you reach a smooth, spreadable consistency.
- Spread the luscious brown butter frosting over your cooled brownies, and let it set before slicing into squares.
Optional: Sprinkle with crushed walnuts for an extra crunch.
