Soft, moist, and topped with a dreamy glaze, Banana Bread Brownies are the perfect mash-up of classic banana bread and chewy, sweet brownies. They bring together the homey comfort of ripe bananas with the indulgent texture of a blondie-style treat. If you’re sitting on a couple of overripe bananas and craving something cozy yet unique, this is the dessert you didn’t know you needed.
These banana-infused bars are a game-changer. The richness of butter and brown sugar paired with the natural sweetness of banana creates a dessert that’s dense and tender. And let’s not forget the simple glaze that soaks into the warm bars, giving them that bakery-style finish with minimal effort. It’s the kind of recipe you whip up once and then find yourself making every single time your bananas start to spot.
Why You’ll Love This Banana Bread Brownies Recipe
These brownies are not your average chocolate squares. They take a fruity, buttery turn that feels both nostalgic and new. You’ll love how easily they come together with basic pantry staples, and how they fill your kitchen with a rich, banana-butter aroma. They’re great for lunchboxes, potlucks, or just because your sweet tooth said so.
And here’s the kicker: the texture is perfectly soft with just a bit of chew. No dry, cakey banana bread here – just bars that slice clean, hold together beautifully, and melt in your mouth.
Can I Add Chocolate or Nuts to These?
Absolutely! These banana bread brownies are a great base for all kinds of additions. Stir in chocolate chips if you’re feeling decadent, or chopped walnuts for a little crunch. A sprinkle of sea salt on top can bring out the caramel notes too. Just be sure not to overdo it on add-ins, as too much moisture can affect the texture. A half cup of chocolate or nuts is plenty for balance.
Ingredients for the Banana Bread Brownies
The beauty of this recipe is that it uses everyday ingredients but combines them in a way that gives extraordinary flavor. Every component plays a role in creating the soft, rich, glazed banana brownie experience.
- Butter – Adds richness and moisture to the batter.
- Granulated Sugar – Sweetens the brownies while allowing the banana flavor to shine.
- Brown Sugar – Brings a caramel depth and extra softness.
- Eggs – Bind the batter and give structure.
- Sour Cream – Keeps the crumb tender and adds a slight tang.
- Ripe Bananas – The star ingredient, full of natural sweetness and flavor.
- All-Purpose Flour – Forms the base and gives body.
- Baking Soda – Helps the brownies rise just enough.
- Salt – Balances sweetness and enhances flavor.
- Vanilla Extract – Adds warmth and depth.

How To Make the Banana Bread Brownies
Step 1: Cream the Butter and Sugars
Start by creaming the butter, granulated sugar, and brown sugar together until light and fluffy. This is key to a soft texture.
Step 2: Add Wet Ingredients
Beat in the eggs, one at a time, followed by the sour cream, mashed bananas, and vanilla extract. Mix until smooth and well combined.
Step 3: Add Dry Ingredients
In a separate bowl, whisk together the flour, baking soda, and salt. Add this dry mixture to the wet batter and mix until just combined. Don’t overmix.
Step 4: Bake
Spread the batter into a greased 9×13-inch baking pan and smooth the top. Bake at 350°F (175°C) for about 25-30 minutes, or until a toothpick inserted in the center comes out clean.
Step 5: Glaze While Warm
While the brownies are still warm, prepare a simple glaze with powdered sugar, milk, and a splash of vanilla. Pour it over the warm bars and let it set as they cool.
Serving and Storing These Banana Bread Brownies
These bars are the kind that somehow taste even better the next day. Once cooled, slice them into squares and store them in an airtight container. They’ll stay fresh at room temperature for about 3 days or up to a week in the fridge.
Planning ahead? They also freeze well. Just layer parchment between slices and freeze in a sealed container. Let them thaw at room temperature before serving.
This recipe feeds about 12 generous squares, but you can easily cut them smaller for bite-size treats.
