Ingredients
To make these delectable Banana Bread Brownies, you’ll need the following:
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 alcohol-free 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 alcohol-free 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 a 9×13-inch pan with cooking spray and parchment paper, leaving an overhang on the sides for easy removal later.
Step 2: Prepare the Brownie Batter
In a large bowl, beat together the granulated sugar, sour cream, softened butter, and eggs until creamy. Mix in the mashed bananas and alcohol-free vanilla extract until well combined.
Step 3: Combine Dry Ingredients
Sift in the all-purpose flour, baking soda, and salt. Carefully mix everything together with a rubber spatula until just combined. Fold in the chopped walnuts gently.
Step 4: Bake the Brownies
Spread the brownie batter evenly into your prepared pan. Bake for about 30-35 minutes or until golden brown. Let them cool in the pan for around 10 minutes before adding frosting.
Step 5: Make the Frosting
While your brownies cool, make the brown butter frosting. In a large pan over medium heat, melt the butter until it starts to boil and turns golden brown. Stir frequently to avoid burning.
Step 6: Frost Your Brownies
Remove the browned butter from heat and pour it into a large bowl. Add half of the powdered sugar along with alcohol-free vanilla extract and milk. Whisk until smooth. Adjust consistency by adding more powdered sugar if necessary. Spread this luscious frosting over your warm banana bread brownies before serving!
Now you’re ready to enjoy these delicious Banana Bread Brownies!

How to Perfect Banana Bread Brownies
Perfecting banana bread brownies is all about attention to detail. Follow these tips for the best results.
- Use Ripe Bananas: The riper the bananas, the sweeter and more flavorful your brownies will be.
- Don’t Overmix: Mix just until combined to keep your brownies tender and moist.
- Check for Doneness: Insert a toothpick; it should come out with a few moist crumbs but not wet batter.
- Cool Completely Before Frosting: Allowing them to cool prevents the frosting from melting and maintains its texture.
- Store Properly: Keep leftovers in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
Best Side Dishes for Banana Bread Brownies
Pairing side dishes with banana bread brownies can create a balanced meal or snack. Here are some excellent choices.

Common Mistakes to Avoid
Avoiding common mistakes can elevate your Banana Bread Brownies to the next level. Here are some pitfalls to watch out for:
- Using Overripe Bananas: While ripe bananas add flavor, too many overripe ones can make the brownies excessively mushy. Aim for ripe but firm bananas for best texture.
- Skipping the Browning Butter: Not browning the butter can lead to a less flavorful frosting. Take the time to brown it; this step adds a rich, nutty flavor.
- Incorrect Baking Time: Overbaking will dry out your brownies. Keep an eye on them in the oven, and do the toothpick test a few minutes before the timer goes off.
- Not Letting Them Cool: Frosting warm brownies can result in a gooey mess. Allow them to cool in the pan for at least 10 minutes before frosting.
- Ignoring Storage Guidelines: Storing brownies improperly can affect their texture and taste. Make sure to use airtight containers or wrap them well.
