Banana Bread Brownies Ingredients
For the Brownies

• Vanilla Extract – Enhances flavor; using pure vanilla will result in a more fragrant treat.

For the Brown Butter Frosting

Step‑by‑Step Instructions for Banana Bread Brownies
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven heats up, take a 15×10 inch jelly roll pan and grease it thoroughly with butter or cooking spray. This will prevent your delicious Banana Bread Brownies from sticking and ensure they come out perfectly!
Step 2: Cream the Ingredients
In a large mixing bowl, add the sugar, sour cream, softened butter, and eggs. Using an electric mixer, cream together these ingredients on medium speed until the mixture is smooth and creamy, which should take about 2–3 minutes. You should see a light and fluffy texture when you’re done.
Step 3: Incorporate Bananas and Vanilla
Next, add the mashed ripe bananas and vanilla extract to your creamy mixture. With a spatula or your mixer on low speed, combine everything until the bananas and vanilla are fully incorporated. The batter should become a lovely yellow color, filled with banana goodness, ready for the dry ingredients!
Step 4: Mix the Flour and Dry Ingredients
Gradually sprinkle in the all-purpose flour along with the baking soda and salt into the banana mixture. Gently fold the dry ingredients in using a spatula, mixing just until no flour streaks remain. Avoid overmixing at this stage to keep your Banana Bread Brownies soft and chewy.
Step 5: Add Walnuts (Optional)
If you’re using walnuts, gently fold them into the batter at this point. This step adds a delightful crunch to your Banana Bread Brownies. Once thoroughly mixed, pour the batter into your greased jelly roll pan, spreading it evenly to ensure uniform baking.
Step 6: Bake the Brownies
Place the pan in the preheated oven and bake for 20–25 minutes. Check for doneness by inserting a toothpick into the center; it should come out clean or with a few moist crumbs attached. The edges of the brownies should appear golden brown and set—watch closely to avoid overbaking!
Step 7: Prepare the Brown Butter Frosting
While the brownies bake, make the brown butter frosting. In a small saucepan over medium heat, melt the butter until it becomes golden brown and releases a nutty aroma—this should take about 5 minutes. Stir frequently to prevent burning, and then remove from heat once done.
Step 8: Whisk in the Frosting Ingredients
Immediately whisk in the powdered sugar, vanilla extract, and milk into the browned butter. Continue mixing until you achieve a smooth and creamy consistency, which should take just a couple of minutes. Your frosting will have a deliciously rich flavor that perfectly complements the brownies.
Step 9: Spread the Frosting
Once the Banana Bread Brownies are out of the oven and slightly cooled, pour the brown butter frosting over the warm brownies. Use a spatula to spread the frosting evenly across the top, allowing the warmth of the brownies to help the frosting melt slightly, making it easier to spread.
Step 10: Cool and Slice
Let the brownies cool in the pan for about 10–15 minutes before cutting them into squares. This helps them set up for better slicing. Once cooled, enjoy your delectable Banana Bread Brownies, whether warm or at room temperature!
Expert Tips for Banana Bread Brownies

• Cooling Matters: Allow the brownies to cool slightly before cutting. This ensures they hold their shape and maintain that luscious, chewy texture.

Banana Bread Brownies Recipe FAQs
What kind of bananas are best for this recipe?
Absolutely! For the best flavor and moisture in your Banana Bread Brownies, choose overripe bananas. Look for bananas with lots of dark spots on the peel; they will be sweeter and mash more easily, contributing to the moist texture of the brownies.
How should I store leftover brownies?
Store your Banana Bread Brownies in an airtight container at room temperature for up to 3 days to keep them deliciously soft and chewy. If you need to keep them longer, placing them in the refrigerator will extend their shelf life to about a week—just be sure to cover them well to avoid drying out.
Can I freeze these brownies?
Very much! To freeze your Banana Bread Brownies, first let them cool completely. Then, cut them into individual slices and wrap each piece tightly in plastic wrap, followed by a layer of aluminum foil. This method will keep them fresh for up to 3 months. When you’re ready to enjoy, simply thaw them in the refrigerator or at room temperature, or heat them in the microwave for a quick treat.
What if my brownies turn out too dense?
If your Banana Bread Brownies come out dense, it’s possible that you may have overmixed the batter after adding the flour. To get that perfect soft and chewy texture, mix the dry ingredients just until combined. For next time, also ensure you’re using fresh baking soda as it helps with rising!
Are there any dietary considerations when making these brownies?
Definitely! If you’re baking for someone with dietary restrictions, you can easily make swaps in this recipe. Use Greek yogurt instead of sour cream for a healthier option, or substitute eggs with an egg replacer to make it vegan-friendly. Additionally, feel free to replace butter with coconut oil for a dairy-free version. Always check ingredient labels if there are specific allergies like nuts in the optional chopped walnuts.
How do I know when the brownies are done baking?
To check for doneness, use the classic toothpick test! Insert a toothpick in the center of the brownies around the 20-minute mark. If it comes out clean or with a few moist crumbs, they are ready. Keep an eye on the edges, which should be a lovely golden brown. If you see dark spots all over the surface, it’s a sign to take them out before they burn.
