3/4 – 1 cup chopped nuts (walnuts or pecans) – optional
2 ounces unsweetened chocolate, coarsely chopped
1/2 cup (1 stick) unsalted butter, softened
1 cup sugar
1/2 teaspoon vanilla
2 eggs, beaten
powdered sugar for garnish
Preheat oven to 325 degrees. Grease and flour an 8-inch square baking dish.
In a small mixing bowl, stir together the flour, salt and nuts (if using). Set aside.
Melt the chocolate and butter in the top of a double boiler over simmering water just until melted. Remove from heat, let cool a bit (so you don’t cook the eggs) and stir in the 1 cup sugar, then the vanilla and eggs. Stir until well blended. Finally, stir in the flour and nut mixture.
Pour into the prepared pan and bake for about 30 to 35 minutes, or until a toothpick inserted in the center comes out clean. Remove from oven and let cool on a wire rack. Sift powdered sugar over the top. Serve at room temperature.
Make ahead: The brownies can be baked and frozen for up to 6 months.
