Step‑by‑Step Instructions for Banana Bread Brownies
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). While the oven warms up, grease a 9×9-inch baking pan with non-stick spray or butter, ensuring the corners and edges are covered. This will help your Banana Bread Brownies release easily after baking, giving you perfect squares to serve.
Step 2: Prepare the Banana Mixture
In a mixing bowl, mash 2-3 overripe bananas until they’re smooth and creamy. Then, add in 1/2 cup of sour cream and 1 teaspoon of vanilla extract, mixing well until everything is combined. The bananas should be fully integrated, creating a luscious base that brings that delightful banana flavor to your brownies.
Step 3: Mix the Dry Ingredients
In a separate large bowl, whisk together 1 cup of granulated sugar, 1/2 cup of unsweetened cocoa powder, and 1 cup of all-purpose flour. Make sure there are no lumps, and the mixture is evenly blended. This step adds the necessary structure and sweetness to your Banana Bread Brownies, setting the stage for deliciousness.
Step 4: Incorporate the Egg Mixture
Add 2 large eggs to the dry ingredients and whisk vigorously until the mixture is fluffy and pale, about 2-3 minutes. The eggs help bind everything together and provide moisture for your brownies. You’ll notice the batter becoming thicker as you mix, embodying the rich texture that makes these brownies so indulgent.
Step 5: Combine Wet and Dry Ingredients
Gently fold the banana mixture into the chocolate batter, being careful not to overmix. Stir in 1/2 cup of chopped walnuts or chocolate chips, ensuring they’re evenly distributed throughout the mixture. This step merges the flavors beautifully, ensuring each bite of your Banana Bread Brownies is a sweet celebration of banana and chocolate.
Step 6: Pour and Smooth the Batter
Once combined, pour the brownie batter into your prepared baking pan. Use a spatula to smooth the top, creating an even layer. This is crucial, as it allows for consistent baking. As you spread the batter, you’ll see the rich chocolatey goodness gleaming, making it hard to resist a taste!
Step 7: Bake to Perfection
Place the baking pan in the preheated oven and bake for 25-30 minutes. To check for doneness, insert a toothpick into the center; it should come out clean or with a few moist crumbs. The edges will be firm, while the center might be slightly soft, which is perfect for achieving that fudgy texture in your Banana Bread Brownies.
Step 8: Cool and Frost
Remove the pan from the oven and allow the brownies to cool in the pan for about 10 minutes. After cooling, prepare your vanilla frosting by mixing powdered sugar with heavy cream until smooth. Spread the frosting generously over the brownies, enhancing their flavor and making them even more irresistible. Finally, let them cool completely before cutting into squares.

Storage Tips for Banana Bread Brownies
Room Temperature: Store leftovers in an airtight container at room temperature for up to 3 days to maintain freshness and flavor.
Fridge: If you want to keep your Banana Bread Brownies longer, refrigerate them in a sealed container for up to 1 week. This will help preserve their moist texture.
Freezer: For longer storage, cut the brownies into squares, wrap each piece in plastic wrap, and place them in a freezer-safe bag. They can be frozen for up to 2 months.
Reheating: To enjoy your frozen Banana Bread Brownies, simply thaw them in the fridge overnight or warm them in the microwave for a few seconds.
Make Ahead Options
These Banana Bread Brownies are a game-changer for meal prep enthusiasts! You can prepare the batter up to 24 hours in advance by mixing all your wet and dry ingredients and storing them in the refrigerator. This keeps the flavors fresh while ensuring you have a quick homemade dessert at hand. Alternatively, bake the brownies, let them cool completely, and store them in an airtight container at room temperature for up to 3 days, or refrigerate for up to 1 week. When you’re ready to enjoy, simply warm them slightly in the oven and frost just before serving for that freshly-baked taste. Whether you choose to make ahead of time or not, these brownies will always be just as delicious!
