½ cup (113 g) unsalted butter, softened
2 large eggs
4 ripe bananas (mashed (about 2 cups))
2 teaspoons pure vanilla extract
2 cups (250 g) all-purpose flour
1 teaspoon baking soda
¾ teaspoon salt
½ cup (60 g) chopped walnuts (optional)

½ cup (113 g) unsalted butter
4 cups (480 g) powdered sugar
1½ teaspoons pure vanilla extract
3 tablespoons milk (more if needed for spreading)

Let’s Make It Together

Prepare the Pan

Preheat your oven to 350°F (175°C).
Grease and flour a 9×13-inch baking dish or line it with parchment paper for easy removal.

Make the Banana Brownie Batter

In a large mixing bowl, cream together the sugar, sour cream, and softened butter until light and fluffy.
Beat in the eggs, mashed bananas, and vanilla extract until smooth and well combined.
In a separate bowl, whisk together the all-purpose flour, baking soda, and salt.
Gradually add the dry ingredients to the wet mixture, mixing just until combined.
Fold in the walnuts if you’re using them to add a delightful crunch.

Bake

Pour the brownie batter into the prepared pan and spread it evenly.
Bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean.
Let the brownies cool in the pan on a wire rack to help them set perfectly.

Prepare the Frosting

In a small saucepan, melt the butter over medium heat and cook it until it turns a light golden brown and smells nutty (about 4–5 minutes).
Remove from heat and let it cool slightly.
Whisk in the powdered sugar, vanilla, and milk until smooth and spreadable.

Frost and Serve

Once the brownies are completely cooled, generously spread the frosting over the top.
Cut into squares or bars, and serve them to your unsuspecting family or friends—they won’t be able to resist!

Delicious Variations to Try

Nutty Chocolate Chip: Add semi-sweet chocolate chips for an extra dose of indulgence.
Zesty Lemon Drizzle: Add a pinch of lemon zest to the batter and drizzle with a light lemon glaze for a refreshing twist.
Peanut Butter Swirl: Before baking, swirl in some creamy peanut butter into the batter for a rich, nutty flavor.
Spicy Pumpkin: Add a cup of pumpkin puree and a teaspoon of pumpkin spice to switch things up for the seasonal months.
