- 1 cup unsalted butter
- 8 oz semi-sweet chocolate, chopped
- 1 1/2 cups granulated sugar
- 1/2 cup brown sugar
- 4 large eggs
- 2 teaspoons vanilla extract
- 1 cup all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 1/2 teaspoon salt
- 1 cup chopped walnuts or pecans (plus more for topping)
- 1 cup unsalted butter (for frosting)
- 2 1/2 cups powdered sugar (for frosting)
- 3/4 cup unsweetened cocoa powder (for frosting)
- 1/4 cup milk (plus more as needed for frosting)
- 1 teaspoon vanilla extract (for frosting)
- Preheat oven to 350°F (175°C). Grease and line two 8-inch round cake pans with parchment paper.
- Melt butter and chocolate together in a saucepan over low heat, stirring until smooth. Let cool slightly.
- Whisk in granulated sugar, brown sugar, eggs, and vanilla extract until well combined.
- In a separate bowl, sift together flour, cocoa powder, and salt.
- Stir dry ingredients into the wet mixture until just combined. Fold in chopped nuts.
- Divide batter evenly between the prepared pans and smooth the tops.
- Bake for 25–30 minutes or until a toothpick inserted in the center comes out with moist crumbs.
- Let cool in pans for 10 minutes, then transfer to a wire rack to cool completely.
- For the frosting, beat butter until creamy. Add powdered sugar, cocoa powder, vanilla, and milk, and beat until smooth and fluffy. Add more milk if needed for spreadable consistency.
- Frost the top of one brownie layer, stack the second on top, and frost the top and sides. Sprinkle with extra chopped nuts.
Notes
- Don’t overbake to maintain the fudgy texture.
- Use high-quality chocolate for the best flavor.
- Chill the cake slightly before slicing for cleaner cuts.
