A perfect mashup of moist banana bread and rich, fudgy brownies—these banana bread brownies are topped with a luscious brown butter frosting for the ultimate dessert.

Ingredients

For the Brownies:

2 large eggs

3 ripe bananas, mashed

1½ cups sugar

1 cup sour cream

½ cup unsalted butter, softened

2 tsp vanilla extract

2 cups all-purpose flour

1 tsp baking soda

¾ tsp salt

½ cup chopped walnuts (optional)

For the Frosting:

½ cup unsalted butter

3 cups powdered sugar

1½ tsp vanilla extract

3 tbsp milk

Instructions

Preheat Oven:
Set oven to 375°F (190°C). Grease a 13×9-inch baking pan.

Mix Wet Ingredients:
In a large bowl, beat together sugar, sour cream, softened butter, and eggs until smooth.

Add Bananas & Vanilla:
Stir in mashed bananas and vanilla extract.

Incorporate Dry Ingredients:
Mix in flour, baking soda, and salt until just combined. Do not overmix.

Add Nuts:
Fold in walnuts, if using.

Bake:
Spread batter evenly in prepared pan. Bake for ~25 minutes, or until golden brown and a toothpick comes out clean.

Make Frosting:
In a saucepan, melt butter over medium heat until browned (nutty aroma). Remove from heat.
Gradually whisk in powdered sugar, adding milk as needed for smooth consistency. Stir in vanilla.

Frost & Cool:
Spread frosting over warm brownies. Let cool completely before cutting into squares.

Notes

Banana Tip: Use very ripe bananas with brown spots for the best flavor.

Don’t Overmix: Mix until just combined to keep brownies moist and tender.

Brown Butter Caution: Watch carefully to avoid burning.

Nut-Free Option: Omit walnuts for a smoother texture.
