Banana Bread Brownies Ingredients
For the Brownies

- Butter (softened) – Adds richness; use unsalted to have better control over saltiness.

- Ripe Bananas (mashed) – The star ingredient that brings sweetness and flavor; opt for overripe bananas for optimal results.

Step‑by‑Step Instructions for Decadent Banana Bread Brownies with Brown Butter Frosting
Step 1: Preheat and Prepare the Pan
Preheat your oven to 375°F (190°C). While the oven warms, line an 8×8-inch baking pan with parchment paper, allowing some overhang for easy removal later. This will ensure that your banana bread brownies bake evenly and release beautifully once done.
Step 2: Mix Wet Ingredients
In a large mixing bowl, combine 1 cup of granulated sugar, ½ cup of softened unsalted butter, and ½ cup of sour cream. Beat with a hand mixer until the mixture is creamy and well combined. Next, add in 2 ripe bananas (mashed) and 1 teaspoon of vanilla extract, mixing again until your batter is smooth and invitingly fragrant.
Step 3: Combine Dry Ingredients
In a separate bowl, whisk together 1 ½ cups of all-purpose flour, 1 teaspoon of baking soda, and ¼ teaspoon of salt. Gradually fold the dry ingredients into the wet mixture with a rubber spatula, being careful not to overmix. Stop once no flour streaks remain—this will keep your brownies soft and fudgy.
Step 4: Add Optional Ingredients
If you’d like to enhance your banana bread brownies, gently fold in ½ cup of chopped walnuts or ½ cup of chocolate chips at this stage. This addition will add delightful texture and flavor to your brownies, making each bite even more enjoyable.
Step 5: Bake the Brownies
Pour the batter into your prepared pan, using a spatula to spread it evenly. Place it in the preheated oven and bake for 30–35 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean. Once baked, remove the pan from the oven and let the brownies cool for about 10 minutes.
Step 6: Prepare the Brown Butter Frosting
While the brownies cool, make the frosting by melting ½ cup of unsalted butter in a saucepan over medium heat. Stir continuously until the butter turns a beautiful golden brown color and has a nutty aroma, about 5–7 minutes. Remove from heat, and let it cool slightly before whisking in 2 cups of powdered sugar, 1 teaspoon of vanilla extract, and a splash of milk until smooth.
Step 7: Frost the Brownies
Once the brownies have cooled slightly but are still warm, spread the brown butter frosting evenly over the top using an offset spatula. This warm frosting will melt slightly into the fudgy brownies, creating a rich and delightful treat. Allow the brownies to cool completely before slicing into squares.
Step 8: Serve and Enjoy
Cut the brownies into squares, and serve them warm or at room temperature. These decadent banana bread brownies make for a perfect dessert or cozy breakfast treat, best enjoyed with a hot cup of coffee or a scoop of vanilla ice cream for added indulgence.
Storage Tips for Banana Bread Brownies
- Room Temperature: Store cooled banana bread brownies in an airtight container at room temperature for up to 4 days to keep them fresh and fudgy.
- Fridge: If you prefer a colder treat, keep brownies in the fridge for up to a week. Allow them to come back to room temperature before enjoying for the best texture.
- Freezer: Wrap individual portions of brownies in plastic wrap and place them in a freezer-safe container. They can be frozen for up to 4 months; just thaw overnight in the fridge before serving.
- Reheating: To enjoy warm brownies again, microwave for 10-15 seconds. The fudgy texture will delight you, especially with a scoop of ice cream on top!
Expert Tips for Banana Bread Brownies
-
Perfectly Ripe Bananas: Use overripe bananas, as they offer the best sweetness and moisture. If they’re not brown enough, your brownies may lack flavor.
-
Do Not Overmix: Mix the batter just until the dry ingredients are incorporated. Overmixing can lead to dense and tough brownies instead of the desired fudgy texture.
-
Watch the Butter: When browning your butter for frosting, keep the heat low and stir constantly. Burnt butter can ruin the nutty flavor of your frosting.
-
Slice with Care: Allow the brownies to cool slightly before slicing to ensure clean edges. Warm brownies can be too soft and may fall apart.
-
Experiment with Nuts: Feel free to switch walnuts for pecans or leave them out entirely for nut-free banana bread brownies. Be creative with your choices!
-
Storage Secrets: Keep any leftovers in an airtight container at room temperature for up to 4 days, or freeze individually wrapped pieces for up to 4 months.

Banana Bread Brownies Recipe FAQs
How do I know if my bananas are ripe enough to use?
Absolutely! For banana bread brownies, overripe bananas are your best friend. Look for bananas with dark spots all over or those that have turned mostly brown. The more ripe they are, the sweeter and more flavorful your brownies will be!
How should I store my banana bread brownies?
Very straightforward! Keep cooled brownies in an airtight container at room temperature for up to 4 days. If you’d like to save them longer, you can refrigerate them for up to a week or freeze them for up to 4 months—just be sure to wrap them individually in plastic wrap before placing them in a freezer-safe container.
Can I freeze the brownies and how?
Yes, you can! To freeze your banana bread brownies, first let them cool completely. Then, cut them into individual squares, wrap each piece tightly in plastic wrap, and place them in a freezer-safe container or bag. They’ll stay fresh for up to 4 months. When you’re ready to enjoy, simply thaw them overnight in the fridge or pop them in the microwave for 10-15 seconds for a warm treat!
What should I do if my brownie batter is too dense?
If you find your brownie batter is too dense, it’s likely due to overmixing. Always mix just until combined, and ensure you’ve properly measured your ingredients. If you feel like it’s still too dry, consider adding a tablespoon of milk or an extra mashed banana to loosen it up. Remember, a fudgy brownie should still be thick but not overly dry!
Are there any allergies I should be aware of with this recipe?
Great question! This recipe contains common allergens like eggs, dairy (butter and sour cream), and nuts (if you choose to add them). If you’re cooking for someone with specific allergies, you can replace the butter with a dairy-free alternative and use ground flaxseed mixed with water as an egg substitute if needed. For a nut-free version, simply omit any added nuts.
