Step‑by‑Step Instructions for Banana Bread Brownies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C), ensuring it reaches the right temperature for baking those delectable Banana Bread Brownies. While the oven heats, prepare a 9×13-inch baking pan by greasing it or lining it with parchment paper for easy removal later.
Step 2: Mash the Bananas
In a large mixing bowl, take 2–3 very ripe bananas and mash them until smooth with a fork or potato masher. Aim for a creamy consistency with minimal lumps; this will infuse delicious banana flavor throughout the brownies. The riper the bananas, the sweeter and more flavorful your brownies will be.
Step 3: Combine the Wet Ingredients
Add the softened unsalted butter, granulated sugar, room-temperature eggs, sour cream, and pure vanilla extract to the mashed bananas. Mix these ingredients well with a whisk or spatula until the mixture is smooth and fully combined, creating a luscious batter base for your Banana Bread Brownies.
Step 4: Whisk the Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. This ensures that the leavening agent is evenly distributed throughout the flour, which will help your brownies rise evenly. Take a moment to enjoy the pleasant aroma of the dry ingredients before proceeding.
Step 5: Combine the Mixtures
Gently fold the dry ingredient mixture into the wet banana batter using a spatula. Stir just until the flour is incorporated and the mixture looks evenly combined. Be cautious not to overmix, as this can lead to dense brownies; you want a moist, tender texture reminiscent of banana bread.
Step 6: Add Optional Ingredients
If you desire a delightful crunch or extra sweetness, fold in optional add-ins like chopped walnuts or mini chocolate chips at this stage. These ingredients enhance the texture and flavor profile of your Banana Bread Brownies, making each bite a joyful surprise.
Step 7: Bake the Brownies
Pour the prepared brownie batter into the greased 9×13-inch pan and spread it evenly with a spatula. Bake in the preheated oven for 25–30 minutes. Keep an eye on the brownies, and they are done when a toothpick inserted in the center comes out clean or with a few moist crumbs attached.
Step 8: Cool & Frost
Once baked, remove the pan from the oven and let the brownies cool completely in the pan on a wire rack. This is crucial for achieving the perfect texture. After cooling, feel free to spread your choice of frosting—be it creamy brown sugar icing or tangy cream cheese frosting—over the brownies to elevate this delicious dessert.

Make Ahead Options
These Banana Bread Brownies are perfect for meal prep enthusiasts looking to save time during busy weeks! You can mash the ripe bananas and mix the wet ingredients up to 24 hours in advance; simply store the mixture in the refrigerator to keep it fresh. Additionally, the dry ingredients can be pre-measured and mixed together, which you can leave in a sealed container on the countertop. When you’re ready to bake, combine the mixtures and add any Optional Add-ins (like walnuts) right before pouring the batter into the baking pan. This way, you maintain the brownies’ excellent texture, ensuring they turn out just as delicious as if you made them fresh!
