Ingredients
This recipe yields a generous batch, perfect for a 9×13 inch pan. You can adjust quantities for smaller pans or double for parties.
For the Banana Bread Brownie Base
- 1½ cups granulated sugar
- 1 cup plain Greek yogurt (or sour cream)
- ½ cup unsalted butter, softened
- 2 large eggs
- 3-4 ripe bananas, mashed
- 2 teaspoons vanilla extract
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- ¾ teaspoon salt
- Optional: 1 cup chopped walnuts or pecans, 1 cup mini chocolate chips
For the Brown Butter Glaze
- 4 tablespoons unsalted butter
- 2 cups powdered sugar
- 1 teaspoon vanilla extract
- 1–2 tablespoons milk
Banana Bread Brownies: Step-by-Step
1. Prepare the Pan and Preheat
Preheat your oven to 375°F (190°C). Grease a 9×13-inch pan with non-stick cooking spray or line with parchment paper for easy removal.
2. Make the Batter
- Cream Butter and Sugar: In a large bowl, beat together the softened butter and granulated sugar until light and fluffy.
- Add Wet Ingredients: Mix in the Greek yogurt (or sour cream), eggs, mashed bananas, and vanilla extract. Beat until the mixture is smooth.
- Incorporate Dry Ingredients: Combine the flour, baking soda, and salt in a separate bowl. Gradually add to the wet mixture, stirring only until just moistened. Avoid overmixing for a tender crumb.
- Mix-Ins: Gently fold in nuts or chocolate chips if desired for added flavor and texture.
3. Bake
Spread the batter evenly into the prepared pan. Bake for 23–28 minutes, or until a toothpick inserted in the center comes out clean or with just a few moist crumbs. Baking time may vary based on your oven and the ripeness of the bananas.
4. Prepare the Brown Butter Glaze
- Brown the Butter: In a skillet, melt the butter over medium heat. Keep a close eye as it simmers. When the butter turns a light golden brown and a nutty aroma emerges, remove from heat immediately—the solids should be just starting to toast, but not burnt.
- Make the Glaze: Whisk in the powdered sugar, vanilla, and 1 tablespoon milk, combining until smooth. Add more milk to adjust consistency if needed.
5. Glaze and Finish
Pour the warm glaze over the brownies while they are still warm in the pan. Spread gently with the back of a spoon for a silky finish. The glaze will set as it cools, creating a delectable topping.
Recipe Variations
| Variation | Description | How to Make |
|---|---|---|
| Nuts | Add crunch and flavor. | Fold in 1 cup chopped walnuts or pecans into batter before baking. |
| Chocolate Chips | Extra chocolatey taste. | Mix in 1 cup mini or regular chocolate chips before baking. |
| Cream Cheese Frosting | Rich, tangy topping option. | Swap brown butter glaze for cream cheese frosting. |
| Lighter Version | Reduced sugar and butter. | Cut sugar by half and use only 3–4 tablespoons butter for the glaze. |
Make Ahead and Storage Tips
- Make Ahead: Bake and glaze up to two days in advance. Store covered in the refrigerator for maximum freshness.
- Freezing: Cool completely. Place in the pan, frost (or leave plain), wrap tightly in both plastic wrap and foil. Freeze for up to 3 months. Thaw at room temperature before serving.
- Leftovers: Keep in an airtight container at room temperature for up to 3 days, or refrigerate for longer shelf-life.
Expert Baking Tips
- Banana Ripeness: Use fully ripe bananas (brown-spotted or blackened peel) for best flavor and moistness.
- Do Not Overmix: Stir just enough to combine ingredients to avoid dense brownies.
- Glaze Timing: Pour glaze while bars are warm for a smooth, shiny finish.
- Custom Size: For thick brownies, use a smaller pan. For party-size bites, cut squares smaller.
Serving Suggestions
- Serve warm with a scoop of vanilla ice cream for a decadent dessert.
- Cut into bite-sized pieces for lunchbox treats or after-school snacks.
- Dust with powdered sugar or a drizzle of chocolate sauce for extra flair.

Frequently Asked Questions (FAQ)
Q: Can I make banana bread brownies gluten-free?
A: Yes, substitute an equal amount of gluten-free 1:1 baking flour for the all-purpose flour. Check baking times as gluten-free blends may vary in absorption.
Q: How do I know when my brownies are done?
A: Insert a toothpick into the center. It should come out clean or with light crumbs. Overbaking will dry out the bars, so check at the minimum time suggested.
Q: Can I skip the glaze?
A: Absolutely. The banana bread brownies are moist and delicious on their own. Try other toppings such as cream cheese frosting, melted chocolate, or just powdered sugar.
Q: What if my bananas aren’t ripe yet?
A: Ripen bananas quickly by placing them in a paper bag for a day or baking them unpeeled at 300°F for 20 minutes until blackened and soft.
Q: Can these be made dairy-free?
A: Yes, use dairy-free butter and swap Greek yogurt or sour cream for plant-based alternatives such as plain coconut or almond yogurt.
Creative Mix-Ins and Twists
- Spices: Add ½ teaspoon ground cinnamon or nutmeg to enhance banana flavor.
- Nut Butters: Swirl peanut butter or almond butter into the batter before baking.
- Fruit: Stir in diced fresh strawberries or blueberries for a fruity variation.
- Marbled Brownies: For a striking swirl, layer half plain banana batter, half chocolate batter (add ¼ cup cocoa powder to one half), then gently swirl together.
Perfect Pairings
- Serve with fresh berries for a refreshing contrast.
- Pair with hot coffee or cold milk for classic comfort.
- Top with toasted coconut shreds for extra crunch and visual appeal.
