Step‑by‑Step Instructions for Banana Bread Brownies
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). Grease a 9×9-inch baking pan with non-stick spray or line it with parchment paper for an easy release. This preparation ensures that your Banana Bread Brownies will bake evenly and not stick, setting the stage for deliciousness!
Step 2: Mash the Bananas
In a mixing bowl, take your ripe bananas and mash them with a fork until you achieve a smooth consistency. This usually takes about 3-5 minutes. Then, stir in the sour cream and vanilla extract until just combined. The sweetness from the bananas will enhance your brownies wonderfully!
Step 3: Mix Dry Ingredients
In a separate bowl, whisk together the granulated sugar, unsweetened cocoa powder, and eggs until you have a light and fluffy mixture, approximately 3-5 minutes. This aeration is essential as it helps to give your Banana Bread Brownies a beautifully rich texture.
Step 4: Combine Mixtures
Gently fold the banana mixture into your dry ingredients, ensuring everything is well incorporated. Gradually add the all-purpose flour and chopped walnuts, being careful to avoid overmixing. This gentle folding technique helps maintain the tender texture of your amazing Banana Bread Brownies.
Step 5: Pour the Batter
Pour the brownie batter into the prepared baking pan and use a spatula to spread it evenly, smoothing out the top to ensure even baking. It’s important to fill the pan to avoid uneven baking, giving you that perfect fudgy consistency we crave in Banana Bread Brownies.
Step 6: Bake
Pop the pan into your preheated oven and bake for 25-30 minutes. To test for doneness, insert a toothpick into the center of the brownies; it should come out clean or with a few moist crumbs attached. Keep a close eye, as overbaking can lead to dry brownies.
Step 7: Cool and Frost
Once out of the oven, let the Banana Bread Brownies cool in the pan for about 10 minutes. After they have cooled slightly, transfer them to a wire rack to cool completely before frosting. Patience here allows the flavors to develop and ensures the frosting won’t melt!
Step 8: Frost and Serve
Prepare your vanilla frosting by beating together unsalted butter, powdered sugar, heavy cream, and vanilla extract until smooth. Once the brownies are cooled, spread the frosting generously on top. Cut into squares and enjoy your irresistibly delicious Banana Bread Brownies with family and friends!

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 fudgy texture and flavor.
- Fridge: If you want them to last longer, refrigerate the brownies for up to 1 week. Just be sure to wrap them tightly to prevent drying out.
- Freezer: For longer storage, cut the brownies into squares and wrap each piece in plastic wrap before placing them in a freezer-safe bag. They can be frozen for up to 2 months. Thaw them in the fridge before enjoying!
- Reheating: To enjoy the brownies warm, simply microwave a square for about 10-15 seconds; this enhances the rich chocolatey flavor and brings back that fresh-baked aroma.
