• 1 teaspoon vanilla extract – enhances all the sweet notes
• 1 cup all-purpose flour – the base of our brownie

• 1/2 teaspoon salt – balances the sweetness

How to Make Banana Bread Brownies

Ready to bring this delicious banana bread brownie bake to life? Follow these simple steps on how to make banana bread brownies.

1. Step 1: Preheat your oven to 375°F (190°C). Grease and flour a 15×10-inch jelly roll pan. This ensures your brownies won’t stick.
2. Step 2: In a large bowl, cream together 1 cup sugar, 1/2 cup sour cream, 1/2 cup butter, and 2 large eggs until the mixture is smooth and fluffy. This creates the rich base for your brownies.
3. Step 3: Mash your 2 medium ripe bananas until they are smooth, then add them to the wet ingredients along with 1 teaspoon vanilla extract. Mix everything on low speed until just combined. The smell of ripe bananas is already impressive!
4. Step 4: In a separate bowl, sift together 1 cup all-purpose flour, 1 teaspoon baking soda, and 1/2 teaspoon salt. Gradually add these dry ingredients to the wet ingredients, mixing only until they are just incorporated. Overmixing can make your brownies tough, so be gentle!
5. Step 5: If you’re using them, gently fold in the 1/2 cup chopped walnuts. Pour the batter into your prepared pan and spread it out evenly.
6. Step 6: Bake for 20-25 minutes. You’ll know they’re done when a toothpick inserted into the center comes out clean. Let the brownies cool in the pan for about 10 minutes before moving on.
7. Step 7: While the brownies cool, prepare the frosting. Melt 1/2 cup butter in a saucepan over medium heat. Watch it closely until it turns a lovely golden brown and smells nutty – this takes about 5-7 minutes. Let it cool slightly.
8. Step 8: In a mixing bowl, whisk the cooled browned butter with 2 cups powdered sugar, 1 teaspoon vanilla extract, and 2 tablespoons milk until you have a smooth, creamy frosting. This is one of my favorite banana bread brownie baking tips – brown butter adds extraordinary depth!
9. Step 9: Spread the delicious frosting evenly over the slightly cooled brownies. Let the frosting set a bit before cutting into bars. Enjoy your homemade banana bread brownies!
