• Chopped Walnuts (optional) – Adds crunch and flavor; can substitute pecans or omit for nut-free version.

Step‑by‑Step Instructions for Banana Bread Brownies
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C) while you prepare a 9×13-inch baking pan. Grease the pan with unsalted butter or line it with parchment paper for easy removal later. This setup ensures your Banana Bread Brownies bake evenly and release perfectly once they’re ready to enjoy.
Step 2: Mash the Bananas
In a large mixing bowl, take 2-3 ripe bananas and mash them with a fork until they are smooth and creamy. You want to achieve a puree-like consistency without any large lumps. The bananas should be deep yellow with plenty of brown spots to maximize sweetness and moisture, the perfect foundation for your Banana Bread Brownies.
Step 3: Mix the Wet Ingredients
Add granulated sugar, melted unsalted butter, room-temperature eggs, sour cream, and vanilla extract to the mashed bananas. Use a whisk or spoon to mix everything together until fully combined. This should take about 1-2 minutes, and the texture should be smooth and slightly glossy, enhancing the moistness of your brownies.
Step 4: Combine the Dry Ingredients
In a separate bowl, whisk together all-purpose flour, baking soda, and salt. This step helps distribute the baking soda throughout the flour, ensuring your Banana Bread Brownies rise evenly. Take your time, as proper mixing here contributes to the overall structure and ensures that your brownies won’t be dense.
Step 5: Fold in the Flour Mixture
Gradually incorporate the dry ingredients into the wet mixture, folding gently with a spatula or wooden spoon. Mix until just combined, about 30 seconds, being careful not to overmix, which can lead to tough brownies. You want this mixture to be slightly lumpy; overworking it can lead to a less desirable texture.
Step 6: Add Optional Mix-ins
If you desire, now is the time to fold in chopped walnuts or mini chocolate chips into the batter. This adds crunch and a touch of extra indulgence to your Banana Bread Brownies. Gently mix until evenly distributed but not overmixed to keep the batter light and fluffy.
Step 7: Bake the Brownies
Pour the batter into your prepared baking pan, smoothing the top with a spatula. Bake in the preheated oven for 25-30 minutes. Keep an eye on them, and check for doneness by inserting a toothpick into the center; it should come out clean or with a few moist crumbs clinging to it.
Step 8: Cool and Frost
Once baked, remove the pan from the oven and let the Banana Bread Brownies cool in the pan for about 10 minutes. After that, transfer them to a wire rack to cool completely before frosting with your choice of brown butter icing or cream cheese frosting. Once frosted, slice into squares and prepare to share the joy!

Helpful Tricks for Banana Bread Brownies
Don’t Overmix: Gently fold the dry ingredients into the wet mixture until just combined. Overmixing can make your Banana Bread Brownies tough instead of tender.
Use Overripe Bananas: The best flavor and moisture come from bananas that are very ripe, with plenty of brown spots. Using underripe bananas will result in less sweetness.
Cooling Time Matters: Allow the brownies to cool before frosting. This prevents the frosting from melting and ensures a beautiful finish on your Banana Bread Brownies.
Toothpick Test: Check for doneness by inserting a toothpick into the center. It should come out clean, or with just a few moist crumbs attached, indicating perfectly baked brownies.
Customize with Care: When adding mix-ins like nuts or chocolate chips, be sure to fold them in gently to maintain the airy texture of the brownies.
How to Store and Freeze Banana Bread Brownies
Room Temperature: Store your Banana Bread Brownies in an airtight container for up to 3 days to maintain their delicious moisture and flavor.
Refrigerator: They can be kept in the fridge for up to 1 week. Simply allow them to come to room temperature before serving for the best taste.
Freezer: Wrap each brownie individually and freeze for up to 3 months. Thaw overnight in the fridge, and enjoy these delightful treats whenever the craving strikes!
Reheating: If you prefer a warm brownie, pop them in the microwave for about 10-15 seconds—perfect for a cozy dessert experience!
Make Ahead Options
These Banana Bread Brownies are perfect for meal prep, saving you time on busy days! You can prepare the batter up to 24 hours in advance—just mix all the wet ingredients and dry ingredients separately, then combine them before you’re ready to bake. Store the prepared batter in the refrigerator to maintain the freshness and prevent browning. If you want, you can also bake the brownies ahead and keep them in an airtight container; they stay delicious for up to 3 days at room temperature or 1 week in the fridge. When it’s time to serve, simply frost them if desired, and enjoy the scrumptious taste of freshly baked Banana Bread Brownies!

Banana Bread Brownies Recipe FAQs
How do I know if my bananas are ripe enough?
Absolutely! Look for deep yellow bananas covered with plenty of brown spots. The more spots, the sweeter and more flavorful they will be. Avoid using bananas that are still green, as they lack the sweetness needed for these delicious Banana Bread Brownies.
What’s the best way to store Banana Bread Brownies?
To keep your Banana Bread Brownies fresh, store them in an airtight container at room temperature for up to 3 days. If you want to extend their life, they will also hold up nicely in the refrigerator for up to a week. Just remember to let them come to room temperature before serving for that fresh-from-the-oven taste!
Can I freeze Banana Bread Brownies?
Yes, you can! To freeze, wrap each brownie individually in plastic wrap, then place them in a zip-top freezer bag. They can be stored in the freezer for up to 3 months. When you’re ready to enjoy, simply thaw them overnight in the refrigerator and then, if desired, reheat in the microwave for about 10-15 seconds to bring back that cozy, warm texture.
What should I do if my brownies turn out too dense?
Very! If your Banana Bread Brownies are dense, it’s often due to overmixing the batter or using too much flour. To avoid this, gently fold the wet and dry ingredients together until just combined—it’s okay if the batter is slightly lumpy! Also, be sure you’re measuring your flour correctly (spooned and leveled), as too much can lead to a dry, heavy result.
Are these brownies suitable for those with nut allergies?
Yes, they can be! You can easily make nut-free Banana Bread Brownies by simply omitting the chopped walnuts or substituting them with a different mix-in like chocolate chips or dried fruit. Always check labels on any ingredients you use to ensure they’re safe for your dietary needs.
