Ingredients
Scale
- 1 ½ cups (300 g) granulated sugar
- 1 cup (240 g) full-fat sour cream
- ½ cup (113 g) unsalted butter, softened
- 2 large eggs
- 3 ripe bananas, mashed (about 1 ½ to 1 ¾ cups)
- 2 teaspoons vanilla extract
- 2 cups (240 g) all-purpose flour
- 1 teaspoon baking soda
- ¾ teaspoon salt
- ½ cup (50–60 g) chopped walnuts (optional)
Frosting (optional):
- ¼ cup (57 g) unsalted butter
- 1 ½ cups (about 180 g) powdered sugar, sifted
- 1 teaspoon vanilla extract
- 1–2 tablespoons milk (as needed for consistency)
Instructions
- Preheat your oven to 375°F (190°C). Grease and line a 9×13-inch pan with parchment paper.
- In a large mixing bowl, beat together the granulated sugar, sour cream, softened butter, and eggs until creamy and slightly fluffy (about 1–2 minutes).
- Stir in the mashed bananas and vanilla extract.
- In a separate bowl, sift together the all-purpose flour, baking soda, and salt.
- Gently fold the dry ingredients into the wet mixture until just combined—do not overmix. Fold in the chopped walnuts if using.
- Spread the batter evenly in the prepared pan and bake for 30–35 minutes.
- Remove from oven and let cool in the pan for about 10 minutes. Meanwhile, prepare the frosting.
- In a small skillet over medium heat, melt ¼ cup butter and cook until the butter solids turn golden brown.
- Transfer the browned butter to a bowl, stir in the powdered sugar and vanilla. Add milk until reaching a spreadable consistency.
- Spread the frosting over the slightly cooled brownies and allow it to set before slicing into 12 squares.
