Ripe bananas provide natural sweetness and moisture.
Unsalted butter adds richness and tender texture.
Granulated sugar sweetens and enhances caramel notes.
Eggs create structure and softness.
Vanilla extract deepens and rounds out flavor.
All-purpose flour forms the base structure of the bars.
Baking soda ensures proper rise and lightness.
Salt balances sweetness and enhances banana flavor.
Sour cream adds moisture and subtle tang.
Brown sugar can be used in the glaze for deeper flavor.
Powdered sugar forms the base of the smooth topping glaze.
Milk helps achieve a pourable glaze consistency.
Directions
Preheat the oven and line a baking pan with parchment paper. In a large bowl, mash the ripe bananas until smooth.
In a separate bowl, cream softened butter and sugar until light and fluffy. Add eggs one at a time, mixing well after each addition. Stir in vanilla extract and sour cream.
Gradually fold in flour, baking soda, and salt until just combined. Stir in the mashed bananas until evenly incorporated.
Spread the batter evenly into the prepared pan. Bake until the center is set and a toothpick inserted comes out clean.
While the brownies cool, prepare the glaze by mixing powdered sugar with milk and a small amount of melted butter if desired. Spread the glaze over the slightly warm brownies and allow it to set before slicing.

Variations and Customizations
Banana Bread Brownies are highly adaptable. I tested this recipe with chopped walnuts folded into the batter, which added a pleasant crunch and depth.
For a richer variation, swirl a small amount of cream cheese mixture into the batter before baking. Chocolate chips can also be added for a sweeter, dessert-like finish.
If you prefer less sweetness, reduce the glaze slightly or omit it entirely. These simple adjustments allow you to tailor the bars while preserving their soft, banana-forward flavor.
