12 ounces semisweet or bittersweet chocolate, chopped
12 tablespoons (1 1/2 sticks) unsalted butter
1/4 teaspoon fine salt
6 large eggs, room temperature
1 1/2 cups granulated sugar
Preheat oven to 325 degrees F. Spray a 9 by 2-inch spring form pan with nonstick spray.
Put the chocolate, butter, and salt in a large microwave safe bowl. Melt in the microwave on 75 percent power for 2 minutes. Stir and microwave again until completely melted, about 2 minutes more. Alternatively, put the chocolate and butter in a heatproof bowl. Bring a saucepan filled with an inch or so of water to a very slow simmer; set the bowl on the pan without touching the water. Stir occasionally until melted.
Beat the eggs and sugar with a standing or handheld mixer until light and thickened, about 8 to 10 minutes. Fold the melted chocolate into the whipped eggs until evenly combined.
Pour the batter into the prepared pan and bake until a toothpick inserted into the center comes out wet but not gooey, about 1 hour and 25 minutes. Remove cake from the oven and cool on a rack.
When ready to serve remove ring from spring form mold. Dust cake with confectioners’ sugar or cocoa powder. Serve with whipped cream and raspberry sauce.
2 pints raspberries
1/4 cup sugar
1 tablespoon lemon juice
Combine raspberries and sugar in a saucepan. Cook until raspberries are broken down, about 10 minutes. Remove from the heat and strain to eliminate seeds.
