Step‑by‑Step Instructions for Banana Bread Brownies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it’s warming up, grease a 9×9-inch baking pan with butter or non-stick spray to ensure your Banana Bread Brownies release easily after baking. This initial step sets the perfect stage for baking your delicious treat.
Step 2: Prepare the Banana Mixture
In a mixing bowl, peel and mash 2-3 ripe bananas until smooth. Then, stir in half a cup of sour cream and a teaspoon of vanilla extract until fully combined. This mixture brings natural sweetness and moisture to your Banana Bread Brownies, so ensure it’s well blended before moving on to the next step.
Step 3: Mix the Dry Ingredients
In a separate bowl, combine one cup of granulated sugar, half a cup of unsweetened cocoa powder, and two eggs. Whisk until the mixture is fluffy and has lightened in color—a sign that it’s well aerated. This step is essential for creating the fudgy texture of the brownies, so whisk vigorously.
Step 4: Combine Wet and Dry Ingredients
Carefully fold the banana mixture into the cocoa mixture until just incorporated. Next, add one cup of all-purpose flour and half a cup of chopped walnuts to the combined mix. Gently stir until no dry flour remains; be careful not to overmix, as this helps achieve the ideal texture for your Banana Bread Brownies.
Step 5: Pour the Batter
Once your batter is well-mixed, pour it into the prepared baking pan. Use a spatula to spread the batter evenly, smoothing the top for consistent baking. It’s important to ensure that there are no air pockets so that your Banana Bread Brownies bake evenly throughout for that perfect fudgy center.
Step 6: Bake the Brownies
Place the pan in your preheated oven and bake for 25-30 minutes. To check for doneness, insert a toothpick into the center—if it comes out clean or with a few moist crumbs, your brownies are ready. If not, give them a few more minutes, keeping a close eye as they bake to avoid overcooking.
Step 7: Cool the Brownies
After baking, remove the pan from the oven and allow the brownies to cool in the pan for about 10 minutes. This step is crucial before frosting, as it prevents the frosting from melting. Once slightly cooled, you can lift the brownies out of the pan for further cooling on a wire rack if desired.
Step 8: Prepare the Frosting
Meanwhile, prepare the frosting by creaming half a cup of unsalted butter in a bowl until smooth. Gradually mix in 1-2 cups of powdered sugar and enough heavy cream to reach your desired consistency. Stir until the frosting is fluffy and ready to complement your Banana Bread Brownies.
Step 9: Frost and Serve
Once the brownies have cooled completely, spread the frosting generously over the top using a spatula. Feel free to get creative with the frosting—you can even sprinkle some chopped walnuts or chocolate chips on top for added texture. Cut them into squares and enjoy this delightful twist on a classic favorite.

How to Store and Freeze Banana Bread Brownies

Banana Bread Brownies Recipe FAQs
How do I select the best bananas for this recipe?

What should I do if my brownies turn out too dry?
Very! If you find that your Banana Bread Brownies came out dry, it could be due to overbaking. It’s essential to check for doneness a few minutes before the suggested baking time.
