Banana bread bars are moist and flavorful and land somewhere between a cake and a bread with the most amazing brown butter frosting on top! Great for breakfast or an afternoon treat with a cup of coffee, both the texture and flavor are crave-worthy!
- 1-1/2 cup sugar
- 1 cup sour cream
- 1/2 cup butter softened
- 2 eggs
- 1-3/4 3 or 4 ripe bananas, mashed (I used 4 bananas)
- 2 teaspoon vanilla extract
- 2 cup all purpose flour
- 1 teaspoon baking soda
- 3/4 teaspoon salt
- 1/2 cup chopped walnuts optional
- 1/2 cup butter
- 4 cup powdered sugar
- 1-1/2 teaspoon vanilla extract
- 3 Tablespoon milk
-
Heat oven to 375F. Grease and flour 15x10-inch jelly roll pan. For the bars, in a large bowl, beat together sugar, sour cream, butter, and eggs until creamy. Blend in bananas and vanilla extract. Add flour, baking soda, salt, and blend for 1 minute. Stir in walnuts.
-
Spread batter evenly into pan. Bake 20 to 25 minutes or until golden brown.
-
For frosting, heat butter in a large saucepan over medium heat until boiling. Let the butter turn a delicate brown and remove from heat immediately.
-
Add powdered sugar, vanilla extract and milk. Whisk together until smooth (it should be thicker than a glaze but thinner than frosting). Using a spatula, spread the brown butter frosting over the warm bars (the frosting will be easier to spread while the bars are still warm).
