Ingredients

For the Banana Bread Brownies:

1 cup granulated sugar
½ cup unsalted butter, softened
2 large eggs
1 cup sour cream
3 ripe bananas, mashed
2 teaspoons pure vanilla extract
2 cups all-purpose flour
1 teaspoon baking soda
½ teaspoon sea salt
½ cup chopped walnuts or pecans (optional)

For the Brown Butter Frosting:

½ cup unsalted butter
4 cups powdered sugar, sifted
1½ teaspoons vanilla extract
3–4 tablespoons whole milk or heavy cream

Preparation

Step 1: Prepare the Oven and Pan

Preheat your oven to 350°F (175°C).
Grease a 9×13-inch baking pan and line it with parchment paper for easy removal.
Set aside while you prepare the batter.

Step 2: Make the Banana Brownie Batter

In a large mixing bowl, cream together the sugar and softened butter until light and fluffy using a hand mixer or stand mixer.
Add the eggs, one at a time, beating well after each addition.
Mix in the sour cream, mashed bananas, and vanilla extract until the mixture is smooth and well incorporated.

Step 3: Combine the Dry Ingredients

In a separate bowl, whisk together the flour, baking soda, and salt.
Gradually add the dry ingredients into the banana mixture and stir gently until just combined.
If using nuts, fold them in at this stage for a nutty texture and flavor contrast.

Step 4: Bake the Banana Bread Brownies

Pour the batter into your prepared baking dish and smooth out the top with a spatula.
Bake in the preheated oven for 25–30 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
Remove the brownies and let them cool completely in the pan before adding the frosting.

Step 5: Prepare the Brown Butter Frosting

In a medium saucepan, melt the butter over medium heat, stirring constantly.
Continue cooking until the butter begins to turn golden brown and gives off a nutty aroma. This should take about 5–7 minutes.
Remove from heat and immediately whisk in the powdered sugar, vanilla extract, and milk.
Continue mixing until smooth and spreadable. Add a splash more milk if needed to reach your desired consistency.

Step 6: Frost and Serve

Once the brownies are cooled, spread the brown butter frosting evenly over the top.
For an added touch, sprinkle more chopped nuts or a dash of cinnamon on top.
Slice into squares and serve.

Variation

Chocolate Chip Banana Brownies: Stir in ½ cup of semi-sweet chocolate chips before baking for extra decadence.
Gluten-Free Version: Substitute all-purpose flour with your favorite 1:1 gluten-free baking flour.
Vegan-Friendly Option: Use vegan butter, a flax egg (1 tbsp flaxseed + 3 tbsp water), and plant-based sour cream.
Cinnamon Swirl Addition: Swirl in a cinnamon-sugar mix before baking for an aromatic layer.
Nut-Free Version: Simply omit the nuts, or replace them with chocolate chunks or shredded coconut.

COOKING Note

Don’t overmix your batter—this keeps the brownies light and tender.
Use overripe bananas with lots of brown spots for the richest flavor and natural sweetness.
The frosting sets quickly—be ready to frost immediately after mixing.
Store leftovers in an airtight container at room temperature for 2 days, or refrigerate for up to 5 days.

Perfect for Brunch Tables: Serve alongside coffee or a mimosa.
Afternoon Pick-Me-Up: Enjoy a square with a latte or iced coffee.

FAQs

Can I freeze Banana Bread Brownies?

Yes, they freeze beautifully. Wrap individual pieces tightly in plastic wrap, then place in an airtight freezer bag. They’ll keep for up to 2 months.

How ripe should my bananas be?

Very ripe with brown speckles or full brown skin. The riper the banana, the sweeter and more flavorful your brownies.

Can I make these without frosting?

Absolutely. They’re still delicious plain, but the brown butter frosting elevates them to an indulgent dessert.

Can I make this in a different size pan?

Yes. An 8×8 pan will make thicker brownies but require a longer baking time (35–40 minutes). Always test with a toothpick for doneness.

How do I make them cakier or denser?

For a cakier texture, use an extra egg. For denser, fudgy brownies, reduce flour by ¼ cup and avoid overmixing.
