Step‑by‑Step Instructions for Banana Bread Brownies
Step 1: Preheat Oven
Begin by preheating your oven to 350°F (175°C). While it’s warming up, grab a 9×13-inch baking dish and grease it generously with butter or cooking spray. This will ensure your Banana Bread Brownies come out effortlessly after baking.
Step 2: Prepare Banana Mixture
In a large mixing bowl, mash 2-3 ripe bananas until smooth, creating a lovely base for your brownies. Next, add in ½ cup of sour cream and 2 beaten eggs. Whisk everything together until it’s well combined and you achieve a light and lemony hue. Set this deliciously fragrant mixture aside for a moment.
Step 3: Combine Dry Ingredients
In another medium bowl, whisk together 1 cup of all-purpose flour, 1/3 cup of cocoa powder, and 1 cup of sugar. If you’re adding nuts, now’s the time to mix in ½ cup of chopped walnuts. Make sure everything is evenly blended, as this will play an essential role in the texture of your Banana Bread Brownies.
Step 4: Mix Together
Gradually introduce the dry ingredient mixture into the banana mixture. Stir gently with a spatula until just combined, keeping an eye out not to overmix—this keeps your brownies wonderfully tender. You’ll want to see a few flour streaks still visible for the best results.
Step 5: Bake
Pour the brownie batter into your greased baking dish, smoothing the top with a spatula for evenness. Place the dish in the preheated oven and bake for about 25-30 minutes. You’ll know they are done when a toothpick inserted into the center comes out with a few moist crumbs attached rather than wet batter.
Step 6: Cool and Frost
Once baked to perfection, remove the Banana Bread Brownies from the oven and allow them to cool completely in the pan. After cooling, whip up a quick vanilla frosting by combining powdered sugar, butter, and vanilla extract, then spread it generously over the cooled brownies. This final touch adds creamy sweetness that complements the rich brownie base beautifully.

Make Ahead Options
These Banana Bread Brownies are perfect for meal prep enthusiasts looking to save time on busy weeknights! You can prepare the batter up to 24 hours in advance by mixing the wet and dry ingredients separately and refrigerating them. This way, you keep the flavors fresh and the batter ready for baking. When you’re ready to enjoy this delightful treat, simply mix the wet and dry components, pour them into the baking dish, and bake as usual. For the frosting, consider making it up to 3 days ahead; just refrigerate in an airtight container, and give it a quick stir before spreading on the cooled brownies. By prepping in advance, you can have these indulgent Banana Bread Brownies ready in a snap—just as delicious and comforting as if they were freshly made!
How to Store and Freeze Banana Bread Brownies
Room Temperature: Store the brownies in an airtight container at room temperature for up to 3 days to keep them fresh and delicious.
