CHOCOLATE CAKE WITH CHOCOLATE GLAZE
Chocolate shavings or Gold-brushed Chocolate Leaves
Using electric mixer, beat egg yolks and 6 tablespoons sugar in large bowl until mixture is very thick and pale, about 3 minutes. Fold lukewarm chocolate mixture into yolk mixture, then fold in vanilla extract. Using clean dry beaters, beat egg whites in another large bowl until soft peaks form. Gradually add remaining 6 tablespoons sugar, beating until medium-firm peaks form. Fold whites into chocolate mixture in 3 additions. Pour batter into prepared pan.
Bake cake until top is puffed and cracked and tester inserted into center comes out with some moist crumbs attached, about 50 minutes. Cool cake in pan on rack (cake will fall).
Gently press down crusty top to make evenly thick cake. Using small knife, cut around pan sides to loosen cake. Remove pan sides. Place 9-inch-diameter tart pan bottom or cardboard round atop cake. Invert cake onto tart pan bottom. Peel off parchment paper.
Place cake on rack set over baking sheet. Spread 1/2 cup glaze smoothly over top and sides of cake. Freeze until almost set, about 3 minutes. Pour remaining glaze over cake; smooth sides and top. Place cake on platter. Chill until glaze is firm, about 1 hour. (Can be made 1 day ahead. Cover with cake dome; store at room temperature.) Garnish with chocolate shavings or leaves. Serve at room temperature.
