Step‑by‑Step Instructions for Banana Bread Brownies
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C). While it heats up, take a 9×13-inch baking dish and grease it lightly or line it with parchment paper, allowing for easy removal of your Banana Bread Brownies after baking. The oven should be hot enough to create that perfect fudgy texture once the batter is poured in.
Step 2: Mash the Bananas
In a large mixing bowl, peel and mash 2-3 very ripe bananas until they reach a smooth consistency. You can use a fork or potato masher for this task! The key is to ensure there are no large lumps in the mixture, which will not only enhance the banana flavor but also ensure a moist brownie.
Step 3: Combine Wet Ingredients
Add the melted unsalted butter, granulated sugar, eggs (preferably at room temperature), sour cream, and pure vanilla extract to the mashed bananas. Whisk the mixture vigorously until well combined and smooth, allowing the ingredients to blend harmoniously. This wet mixture sets the foundation for your delightful Banana Bread Brownies.
Step 4: Mix Dry Ingredients
In another bowl, whisk together the all-purpose flour, baking soda, and salt. This step is crucial for achieving a balanced flavor and proper texture, as the baking soda will help the brownies rise just right while counteracting the sweetness. Make sure there are no clumps in your dry ingredients before moving to the next step.
Step 5: Combine Mixtures
Gently fold the dry ingredients into the wet banana mixture using a spatula or wooden spoon. Be cautious not to overmix; just combine until you no longer see dry flour. This will prevent your Banana Bread Brownies from becoming dense and ensure that they remain soft and chewy in texture.
Step 6: Add Optional Ingredients
If you’re feeling adventurous, this is the time to fold in any optional ingredients like chopped walnuts or chocolate chips to enhance the flavor and texture of your brownies. Gently stir until everything is evenly distributed throughout the batter, adding that delightful crunch or sweetness as you prefer.
Step 7: Bake the Brownies
Transfer the brownie batter into the prepared baking dish, spreading it evenly with a spatula. Place it in the preheated oven and bake for 25-30 minutes. Keep an eye on it, and when a toothpick inserted into the center comes out clean or with a few moist crumbs, your banana bread brownies are done!
Step 8: Cool and Add Frosting
Once baked, remove the dish from the oven and allow your Banana Bread Brownies to cool completely in the pan on a wire rack. This cooling period is essential before adding any optional frosting like brown butter icing or cream cheese frosting, ensuring that the toppings hold well without melting.
Step 9: Slice and Serve
After cooling, remove the brownies from the pan using the parchment paper, if used, and slice them into squares or bars. Serve these delightful Banana Bread Brownies as a sweet snack or dessert, and share with family and friends—enjoy the chorus of compliments on your delicious creation!

Make Ahead Options
These Banana Bread Brownies are perfect for busy home cooks looking to save time! You can prepare the brownie batter up to 24 hours in advance and refrigerate it in an airtight container; this allows the flavors to develop beautifully. Just be sure to give the batter a gentle stir before baking. If you want to go a step further, you can also bake the brownies ahead of time and store them in an airtight container for up to 3 days at room temperature or refrigerate them for up to 1 week. To maintain their moistness, place a slice of bread in the container, which helps prevent drying out. When you’re ready to serve, simply slice and enjoy or warm them up briefly in the microwave for that freshly-baked taste!

Banana Bread Brownies Recipe FAQs
What kind of bananas should I use for Banana Bread Brownies?
Absolutely, the riper the bananas, the better! Aim for bananas that are heavily speckled or even almost black. Four very ripe bananas (about 2 cups) will give you the sweetest flavor and moistest texture for your brownies.
How should I store Banana Bread Brownies?
I recommend storing your Banana Bread Brownies in an airtight container at room temperature, where they will stay fresh for up to 3 days. If you opt to refrigerate them, they can last up to 1 week. Just bring them to room temperature before serving for that perfect fudgy bite!
Can I freeze leftover Banana Bread Brownies?

When you’re ready to enjoy them, simply thaw overnight in the fridge or microwave for 10-15 seconds for a warm treat!
What should I do if my Banana Bread Brownies are too dense?
No worries! If you find your brownies are denseness, it might be due to overmixing the batter. Remember, gentle folding is key—mix until just combined.

Are there any allergy considerations for Banana Bread Brownies?
Definitely! If you’re adapting this recipe for allergy concerns, you can substitute ingredients such as using gluten-free flour in place of all-purpose flour.
