Flourless Chocolate Cake with Toasted Hazelnuts

What is Valentine’s Day without something rich and chocolately?

This cake was quite delicious. We forgoed the brandied cherries (who plans a week ahead? seriously) but even without them it was excellent. Not too rich. I turned it into a dairy-free cake by substituting margarine and soy creamer for the butter and heavy cream.

Flourless Chocolate Cake with Toasted Hazelnuts

Recipe from Bon Appetite.

Ingredients
Cake
10 ounces bittersweet or semisweet chocolate, chopped
1 1/4 cups (2 1/2 sticks) unsalted butter, diced
10 large egg yolks
1/2 cup plus 6 tablespoons sugar
2 teaspoons vanilla extract
1/4 teaspoon salt
9 large egg whites

Ganache
8 ounces bittersweet or semisweet chocolate, chopped
1 cup heavy whipping cream
1 1/2 cups hazelnuts, toasted, coarsely chopped

Directions
For cake:
Position rack in center of oven and preheat to 350°F. Butter 10-inch-diameter springform pan with 23/4-inch-high sides. Line bottom of pan with parchment paper round. Place chocolate and 1 1/4 cups butter in medium metal bowl. Set bowl over saucepan of simmering water; stir until mixture is melted and smooth. Remove bowl from over water; cool to lukewarm, about 10 minutes.

Using electric mixer, beat egg yolks and 1/2 cup sugar in large bowl until very thick and pale yellow in color, about 5 minutes. Beat in vanilla and salt. Gently fold chocolate mixture into yolk mixture. Using clean dry beaters, beat egg whites and remaining 6 tablespoons sugar in another large bowl until peaks form. Fold 1/3 of beaten whites into chocolate mixture. Fold in remaining whites in 2 additions. Transfer batter to prepared pan.

Bake cake until tester inserted into center comes out with moist crumbs attached, about 45 minutes (cake will be puffed and soufflé-like while baking). Cool cake in pan on rack 15 minutes (cake will fall in center). Run knife around cake sides to loosen; press edge of cake down to make level with center. Remove pan sides and cool cake completely. DO AHEAD Can be made 1 day ahead. Cover and store at room temperature.

For ganache:
Combine chocolate and cream in medium metal bowl. Set bowl over saucepan of simmering water and stir until chocolate is melted and mixture is smooth. Remove bowl from over water; let stand until ganache cools slightly but is still pourable, about 5 minutes.

Place cooled cake on rack set over rimmed baking sheet. Pour 1/2 cup ganache over top of cake. Using offset spatula, quickly spread ganache over top and sides of cake. Freeze cake 3 minutes. Pour remaining ganache over top of cake. Working quickly but gently and grasping pan bottom and rack together, slightly tilt rack with cake from side to side, allowing ganache to flow evenly over top and down sides of cake; smooth sides with offset spatula. Press hazelnuts onto sides of cake to adhere. Chill cake until ganache is set, about 1 hour. DO AHEAD Can be made 1 day ahead. Cover with cake dome and keep refrigerated. Let stand at room temperature 45 minutes before serving.
