These Banana Bread Brownies fuse the cozy taste of banana bread with the decadent feel of fudgy brownies, all finished with a rich brown butter frosting. These bars are moist and dense and studded with ripe bananas and crispy walnuts.
The nuttiness and sweetness of the brown butter frosting goes beautifully with the banana base, and these brownies are a snack you won’t soon forget. Serve them at parties, take them to potlucks, eat them as a comforting snack with your favorite cup of coffee or tea. I was already addicted after a slice of banana bread brownies.

Key Ingredients:
Sugar: Adds sweetness to disguise the banana flavor.
Sour Cream: Gives these brownies the super tender moist consistency, & a touch of tang.
Butter: Its a key player in the batter as well as the frosting as it helps create a rich buttery flavor.
Eggs : They bind the ingredients together and add to the soft texture.
Bananas: You will need ripe bananas for sweetness and that signature banana-bread taste.
Vanilla Extract: This adds brightness to the flavor in both the brownies and frosting.
Flour: All-purpose flour is the backbone of the brownies, providing structure while also allowing them to be soft.
Baking Soda: Guarantees the brownies get a little lift, so they’re fluffy.
Walnuts: To add a delicious crunch and nutty taste (optional, but very highly recommended).
Powdered Sugar: The base of the creamy brown butter frosting.
Milk: Adjusts the frosting’s consistency to make it smooth and spreadable.
