Step‑by‑Step Instructions for Banana Bread Brownies
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C) while you prepare your ingredients. Grease a 15×10-inch jelly roll pan with butter or line it with parchment paper for easy release. This early step sets the stage for baking your luscious Banana Bread Brownies to perfection.
Step 2: Cream the Mixture
In a large mixing bowl, combine sugar, sour cream, softened butter, and eggs. Beat the mixture with a hand mixer or whisk until it’s smooth and creamy, taking about 2-3 minutes. This creaming process adds air to the batter, ensuring your brownies will be light and fluffy once baked.
Step 3: Incorporate the Bananas and Vanilla
Now add the mashed bananas and vanilla extract to your creamed mixture. Stir gently until everything is well combined, allowing the sweet banana flavor to infuse the batter. You should see a cohesive mixture with a hint of banana aroma—this is your base for the indulgent Banana Bread Brownies.
Step 4: Add Flour and Leavening Agents
Sift in the all-purpose flour, baking soda, and salt to the banana mixture. Use a spatula to fold the dry ingredients gently until just combined and smooth—overmixing can lead to dense brownies. If you’re feeling adventurous, fold in chopped walnuts for added texture and flavor.
Step 5: Spread the Batter
Pour the prepared batter into your greased jelly roll pan, using a spatula to spread it evenly. Ensure the batter reaches the edges of the pan for uniform baking. This helps your Banana Bread Brownies bake evenly, with a golden-brown top that’s visually appealing.
Step 6: Bake the Brownies
Place the pan in the preheated oven and bake for 20-25 minutes. Keep an eye on them; they’re done when the tops are golden brown and a toothpick inserted in the center comes out clean. As the brownies bake, the warm scent of bananas will fill your kitchen, inviting everyone to gather around.
Step 7: Prepare the Frosting
While the brownies cool, make the brown butter frosting. In a saucepan over medium heat, melt the butter, stirring occasionally until it turns golden brown and emits a nutty aroma, about 5-7 minutes. Be careful not to burn the butter, as it adds a rich depth of flavor to the frosting.
Step 8: Mix the Frosting Ingredients
Once your butter is browned, remove it from the heat and whisk in powdered sugar, vanilla extract, and milk. Mix until you achieve a smooth, spreadable consistency. If it’s too thick, add a bit more milk; if it’s too thin, sprinkle in more powdered sugar. This frosting will wonderfully complement your moist Banana Bread Brownies.
Step 9: Frost and Serve
After the brownies have cooled for about 10 minutes, frost them generously with the warm brown butter frosting. This step adds a rich finish to the brownies and enhances the flavors. Slice into squares and serve warm or at room temperature, either as a delightful dessert or an indulgent breakfast treat.
Expert Tips for Banana Bread Brownies
Watch the Butter: Be attentive while browning the butter; it can burn quickly, which affects the flavor of your frosting.
Use Overripe Bananas: For the best flavor and moisture in your Banana Bread Brownies, opt for very ripe bananas with brown spots.
Avoid Overmixing: When combining the dry ingredients, mix just until smooth to prevent dense brownies.
Cool Before Frosting: Allow the brownies to cool slightly before adding the warm frosting; this helps absorb flavors beautifully.
Adjust Baking Time: If using a different pan size, keep a close eye on the baking time, as this may vary up to 10 minutes.
Storage Tips for Banana Bread Brownies
Room Temperature: Store the frosted Banana Bread Brownies in an airtight container at room temperature for up to 3 days to maintain their softness and flavor.
Fridge: If you prefer a chilled treat, you can refrigerate the brownies for up to a week. Just remember to place them in an airtight container to prevent them from drying out.
Freezer: For longer storage, freeze un-frosted brownies in an airtight container for up to 2 months. Allow them to thaw completely before frosting for a delicious treat anytime!
Reheating: Enjoy warm brownies by placing them in a microwave for about 10-15 seconds. This simple step revives their gooey texture and enhances the flavors!

Banana Bread Brownies Recipe FAQs
What type of bananas should I use for the best flavor?
Absolutely! The best bananas for this recipe are those that are overripe, with plenty of brown spots on the peel. They should feel soft and squishy when you gently squeeze them. This sweetness and moisture will really enhance the flavor of your Banana Bread Brownies, creating that luscious texture we all love.
How should I store my Banana Bread Brownies?
You can store your frosted Banana Bread Brownies at room temperature in an airtight container for up to 3 days. They’ll maintain their softness and delicious flavor this way! If you prefer a chilled treat, just pop them in the fridge for up to a week. Just be sure to keep them covered tight to prevent drying out!
Can I freeze Banana Bread Brownies and how?
Yes, you can! To freeze your un-frosted Banana Bread Brownies, wrap them tightly in plastic wrap and then place them in an airtight container. They can be stored in the freezer for up to 2 months. When you’re ready to enjoy them, simply thaw at room temperature and frost them afterward for the best flavor.
What should I do if my brownies come out dry?
If your Banana Bread Brownies are dry, it’s usually due to overbaking. Make sure to check them at the 20-minute mark. If you’re unsure, a toothpick should come out with a few moist crumbs, not completely clean. Also, make sure your bananas are overripe for plenty of moisture and flavor. And remember, a dab of frosting can also help bring back some moisture and enhance the overall enjoyment!
Are there any dietary considerations I should note?
If you’re cooking for someone with a nut allergy, you can easily leave out the chopped walnuts or substitute them with chocolate chips if desired. For a vegan option, replace the eggs with flax eggs by mixing 1 tablespoon of ground flaxseed with 2.5 tablespoons of water, letting it sit until it thickens. You’ll still achieve a delightful batch of Banana Bread Brownies without the worry!
