how to make Banana Bread Brownies
Ingredients:
For the Brownies:


- 1 cup (200 g) granulated sugar
- 1 cup (240 ml) sour cream (or plain Greek yogurt)
- 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)
For the Frosting:



- 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)
Directions:
-
Prepare the Pan: Preheat the oven to 350°F (175°C). Grease and flour a 9×13-inch baking dish or line it with parchment paper.
-
Make the Banana Brownie Batter: In a large mixing bowl, cream together the sugar, sour cream, and softened butter until it’s light and fluffy. Beat in the eggs, mashed bananas, and vanilla extract until smooth.
-
In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, mixing just until combined. Fold in the walnuts if you are using them.
-
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 it cool in the pan on a wire rack.
-
Prepare the Frosting: In a small saucepan, melt the 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 the powdered sugar, vanilla, and milk until smooth and spreadable.
-
Frost and Serve: Spread the frosting over the cooled brownies. Cut into squares or bars and serve.

FAQs
Can I use frozen bananas?
Yes, you can use frozen bananas. Just thaw them and drain any excess liquid before mashing.
What can I substitute for sour cream?
You can substitute plain Greek yogurt for sour cream if you prefer. It works the same way!
How do I know when the brownies are done baking?
Check for doneness by inserting a toothpick in the center of the brownies. If it comes out with a few moist crumbs, they are ready. If it comes out wet, they need more time.
