How to Make It

Follow these simple steps to create your delicious brownies.

1. 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.

2. Make the Banana Brownie Batter

In a large mixing bowl, cream together sugar, sour cream, and softened butter until light and fluffy. Beat in eggs, mashed bananas, and vanilla extract until the mixture is smooth.

3. Mix the Dry Ingredients

In a separate bowl, whisk together flour, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, mixing just until combined.

4. Fold in the Walnuts

Gently fold in the chopped walnuts, if using, to add a delicious crunch to your brownies.

5. Bake

Pour the 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.

6. Prepare the Frosting

In a small saucepan, melt ½ cup of unsalted butter over medium heat and cook until it turns a light golden brown and smells nutty (about 4–5 minutes). Remove from heat and let it cool slightly. Whisk in powdered sugar, vanilla, and milk until smooth and spreadable.

7. Frost and Serve

Spread frosting over the cooled brownies. Cut into squares or bars and serve to eager friends and family.

How to Store It

Tips for Best Results
