For the Brownies
- 1 1/2 cups granulated sugar
- 1 cup sour cream
- 1/2 cup butter, softened
- 2 large eggs
- 3-4 ripe bananas, mashed
- 2 teaspoons vanilla extract
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- 3/4 teaspoon salt
- 1/2 cup chopped walnuts
For the Frosting
- 1/4 cup butter
- 3-4 cups powdered sugar
- 1 1/2 teaspoons vanilla extract
- 2-3 tablespoons milk
How to Make Banana Bread Brownies
Step 1: Preheat the Oven
Preheat your oven to 375 degrees Fahrenheit. Grease and line your 9×13-inch baking pan with cooking spray and parchment paper, ensuring there’s an overhang on the sides for easy removal.
Step 2: Prepare the Batter
In a large bowl, beat together the granulated sugar, sour cream, softened butter, and eggs until creamy. Then mix in the mashed bananas and vanilla extract until fully combined.
Step 3: Combine Dry Ingredients
Sift in the all-purpose flour, baking soda, and salt into your banana mixture. Using a spatula, carefully fold these dry ingredients in until just combined. Gently mix in the chopped walnuts.
Step 4: Bake the Brownies
Spread the batter evenly into your prepared pan. Bake for 30-35 minutes or until golden brown. Once baked, allow them to cool in the pan for about 10 minutes before frosting.
Step 5: Make the Frosting
While your brownies cool, prepare the frosting. In a large pan over medium heat, melt the butter until it boils and browns slightly. Stir frequently to avoid burning. Once browned, remove from heat and transfer it to a mixing bowl.
Step 6: Frost Your Brownies
Add half of the powdered sugar along with vanilla extract and milk into the bowl with browned butter. Whisk until smooth; add more powdered sugar as needed for desired consistency. Spread this delicious frosting over your warm banana bread brownies. Serve them up and enjoy!

Common Mistakes to Avoid
When making Banana Bread Brownies, it’s easy to overlook some details. Here are common mistakes to watch out for:
- Skipping the ripeness of bananas: Using unripe bananas can lead to a less sweet and flavorful brownie. Make sure your bananas are fully ripe with brown spots for the best results.
- Not measuring flour correctly: Too much flour can make your brownies dense and dry. Use a kitchen scale or fluff the flour before spooning it into a measuring cup for accuracy.
- Ignoring cooling time: Frosting warm brownies can lead to a melted mess. Allow your Banana Bread Brownies to cool in the pan for at least 10 minutes before adding the frosting.
- Overmixing the batter: Overmixing can result in tough brownies. Mix just until ingredients are combined to ensure a moist and tender texture.
- Using cold ingredients: Cold eggs or butter can lead to uneven mixing. Allow your eggs and butter to come to room temperature before using them in the recipe.
