Preparation Phase & Tools to Use
Before diving into the delightful process of baking Banana Bread Brownies, it’s essential to prepare your kitchen and gather your tools. Start by preheating your oven to 350°F (175°C) to ensure it reaches the perfect temperature by the time your batter is ready. Locate a 9×13-inch baking pan and grease it lightly or line it with parchment paper for easy removal of the brownies once they’re baked.
In addition to your baking pan, gather mixing bowls for combining ingredients, a whisk for stirring, and a spatula for folding in any optional add-ins like nuts or chocolate chips. A mixer comes in handy for creaming the butter and sugar—whether you opt for a hand mixer or a stand mixer, this will make your preparation even more efficient.
Lastly, make sure you have measuring cups and spoons on hand for accuracy. Organization is key, so perhaps arrange your ingredients in the order they’ll be used to make the cooking process smoother and more enjoyable.

Ingredients
This recipe calls for ingredients that are likely found in your kitchen or can be easily sourced:
- 1 cup unsalted butter, softened
- 2 cups granulated sugar
- 3 large eggs
- 1 tablespoon vanilla extract
- 1 1/2 cups mashed ripe bananas (about 3–4 bananas)
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 cup sour cream
- 1/2 cup chopped walnuts or mini chocolate chips (optional)
- 1/2 cup unsalted butter (for frosting)
- 1/4 cup whole milk
- 1 teaspoon vanilla extract (for frosting)
- 3 to 4 cups powdered sugar (for frosting)
Instructions
Step 1: Prepare Your Baking Pan
To begin, preheat your oven to 350°F (175°C). This ensures optimal baking conditions for your brownies. While the oven is warming up, take a 9×13-inch baking pan and grease it with butter or line it with parchment paper. Lining the pan with parchment paper can help with easy removal of the brownies later on.
Step 2: Cream the Butter and Sugar
In a large mixing bowl, cream together the softened butter and granulated sugar using a mixer until the mixture becomes light and fluffy. This step is crucial as it adds air to the mixture, making for lighter brownies. Once creamy, add the eggs one by one, ensuring to mix well after each addition. Then, stir in the vanilla extract to infuse additional flavor.
Step 3: Incorporate the Bananas and Sour Cream
Next, gently mix in the mashed bananas along with the sour cream. These ingredients not only contribute moisture but also enhance the richness of the brownies. Ensure everything is combined well but take care not to overmix at this stage; a few lumps are okay.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually fold the dry mixture into the wet ingredients, combining gently until just incorporated. This prevents the development of gluten, ensuring tender brownies.
Step 5: Add Optional Ingredients
If you chose to include nuts or mini chocolate chips, this is the time to fold those in. These additions will provide a delightful texture contrast and flavor boost to your brownies. Aim for an even distribution for the best results.
Step 6: Bake the Brownies
Pour the combined batter into the prepared baking pan, ensuring it’s spread into an even layer. Place the pan in your preheated oven and bake for 25–30 minutes. You’ll want to keep an eye on it; the brownies are ready when a toothpick inserted into the center comes out clean or with just a few crumbs clinging to it.
Step 7: Cool and Frost
After baking, allow the brownies to cool completely in the pan placed on a wire rack. Cooling is crucial for letting the brownies set and prevents the frosting from melting into a gooey mess. Meanwhile, prepare the frosting by melting butter in a saucepan, removing it from heat, and stirring in the milk and vanilla extract. Gradually add powdered sugar until the mixture is smooth and spreadable.
Step 8: Enjoy!
After the brownies have cooled, spread the delicious frosting over the top without hesitation. Let it set for around 15 minutes before slicing them into squares to serve. Your personal Banana Bread Brownies are ready to be enjoyed by friends and family—what a perfect way to brighten up any day!

Variations
If you’re looking to mix things up with your Banana Bread Brownies, consider these delightful variations:
- Protein: Add a protein boost by mixing in a scoop of your favorite protein powder.
- Vegetables: Incorporate shredded zucchini or carrots for a healthy twist.
- Spices: Enhance flavor by adding cinnamon, nutmeg, or a pinch of ginger to the batter for some warmth.
Cooking Notes
- For the best tasting brownies, be sure to use very ripe bananas. They should have plenty of brown spots for optimal sweetness.
- Never rush the cooling step before frosting. This ensures a perfectly creamy and thick frosting that holds its shape.
- If you have leftover brownies, store them in an airtight container at room temperature for up to three days. They can also be refrigerated for longer freshness.

- Experiment with different types of frosting, such as cream cheese frosting or chocolate ganache, for unique twists.
