Banana Bread Brownies Ingredients
• Here’s everything you need to create your irresistible banana bread brownies!
For the Brownies
- Granulated Sugar – Adds sweetness and structure; consider using brown sugar for a richer flavor.
- Sour Cream – Contributes moisture and tenderness; plain Greek yogurt works well as a substitute.
- Butter (Softened) – Provides richness and flavor; margarine can be used for a non-dairy option.
- Eggs – Acts as a binding agent and adds moisture; flax eggs or applesauce are great vegan alternatives.
- Ripe Bananas (3-4) – Essential for natural sweetness and moisture; overripe bananas are best—the star of banana bread brownies!
- Vanilla Extract (2 tsp) – Enhances flavor; imitation vanilla is an affordable option if you’re keeping costs down.
- All-Purpose Flour (2 cups) – Gives structure to the brownies; whole wheat flour can add a dense texture.
- Baking Soda (1 tsp) – Helps brownies rise; if you’re out, baking powder can work too, just adjust the amount.
- Salt (3/4 tsp) – Balances the sweetness; no substitutes are necessary.
- Chopped Walnuts (1/2 cup) – Adds a delightful crunch and flavor; pecans or chocolate chips also make great alternatives.
For the Frosting
- Butter (for Frosting – 1/4 cup) – Richness in frosting; margarine is an alternative if you prefer non-dairy.
- Powdered Sugar (3-4 cups) – Provides sweetness and texture; it’s best to avoid sugar alternatives here for optimal frosting.
- Vanilla Extract (for Frosting – 1.5 tsp) – Imparts flavor, just like in the brownies!
- Milk (2-3 tbsp) – Adjusts frosting consistency; non-dairy milk can be a suitable substitute.

Step‑by‑Step Instructions for Banana Bread Brownies
Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). While the oven warms up, take a 9×13-inch baking pan and line it with parchment paper for easy removal of the brownies later. This essential step ensures your Banana Bread Brownies will bake evenly and release effortlessly once they are done.
Step 2: Cream the Ingredients
In a large mixing bowl, combine 1 cup of granulated sugar with 1/2 cup of softened butter and 1/2 cup of sour cream. Using an electric mixer, blend these ingredients together until the mixture is light, fluffy, and creamy, which should take about 2-3 minutes. Once well combined, stir in the mashed ripe bananas and vanilla extract until fully incorporated.
Step 3: Combine Dry Ingredients
Next, grab another bowl to whisk together 2 cups of all-purpose flour, 1 teaspoon of baking soda, and 3/4 teaspoon of salt. After mixing those dry ingredients, gently fold them into the banana mixture along with 1/2 cup of chopped walnuts. Be careful not to overmix; stop as soon as you see no flour streaks left, as this keeps your Banana Bread Brownies tender and moist.
Step 4: Bake the Brownies
Pour the brownie batter into your prepared baking pan, spreading it evenly to create a smooth layer. Place the pan in the preheated oven and bake for 30 to 35 minutes. Look for a golden-brown top and a toothpick inserted into the center should come out clean; these cues signal your Banana Bread Brownies are perfectly baked!
Step 5: Cool Down
Once baked, remove the brownies from the oven and cool in the pan for about 10 minutes. This brief cooling period allows them to set and makes it easier to add frosting later. After the initial cooling, transfer the brownies to a wire rack to cool completely before frosting them.
Step 6: Make the Brown Butter Frosting
While the brownies are cooling, prepare your brown butter frosting. In a saucepan over medium heat, melt 1/4 cup of butter, swirling occasionally, until it turns a deep golden brown and smells nutty—about 5-7 minutes. Immediately remove from heat and whisk in 3-4 cups of powdered sugar and 1.5 teaspoons of vanilla extract. Gradually add 2-3 tablespoons of milk until smooth and well combined.
Step 7: Frost and Serve
Once the brownies are completely cool, pour the rich brown butter frosting over them, spreading it evenly across the top for that irresistible finish. After frosting, slice into squares and serve your delightful Banana Bread Brownies. The combination of the fudgy brownie with the rich frosting is simply heavenly!

What should I do if my brownie batter is too thick?
If you find your batter a bit too thick, don’t worry! You can add a tablespoon or two of milk to loosen it up. Mix gently until just combined—be careful not to overmix as that can lead to dense brownies. Aim for a texture that’s smooth and spreadable!
Are there any dietary considerations for these brownies?
Yes, definitely! If you have allergies, you can modify the recipe. For nut-free options, feel free to omit the walnuts or substitute them with chocolate chips. Additionally, you can use flax eggs or applesauce to make it vegan, along with margarine instead of butter for a non-dairy option.
