Classic Fudge Walnut Brownies are rich, chocolatey, and perfectly fudgy with a crunchy walnut topping. Made with bittersweet chocolate, cocoa powder, and brown sugar, these homemade brownies bake up moist and decadent in just one pan. Ideal for dessert, bake sales, or holiday treats, they pair well with milk, coffee, or hot chocolate.

Ingredients

¾ cup all-purpose flour
1 cup granulated sugar
¾ cup unsweetened cocoa powder
½ cup packed brown sugar
½ teaspoon baking powder
¼ teaspoon salt
4 ounces bittersweet chocolate, coarsely chopped, divided
⅓ cup milk (2% or whole)
6 tablespoons butter
1 teaspoon pure vanilla extract
2 large eggs, lightly beaten
½ cup chopped walnuts, divided

Instructions

Preheat the oven to 350°F (175°C). Grease an 8- or 9-inch square baking dish with nonstick cooking spray.
In a large mixing bowl, combine the flour, granulated sugar, cocoa powder, brown sugar, baking powder, and salt. Set aside.
In a small saucepan over low heat, melt half of the chopped bittersweet chocolate with the milk, stirring constantly. Add the butter and continue stirring until fully melted. Remove from heat and stir in the vanilla extract.
Pour the melted chocolate mixture into the flour mixture and stir until slightly combined.
Add the eggs, remaining chocolate, and ¼ cup of the walnuts. Stir until just combined.
Pour the batter into the prepared baking dish and sprinkle with the remaining ¼ cup walnuts.
Bake until a wooden pick inserted in the center comes out with moist crumbs, about 20–22 minutes for a 9-inch dish or 22–26 minutes for an 8-inch dish. The edges should feel set while the center remains slightly soft; it will continue to firm as it cools.
Remove from the oven and let cool completely in the pan before slicing and serving.
