- Let eggs stand at room temperature for 30 minutes. Line a greased 15-in. x 10-in. x 1-in. baking pan with waxed paper; grease the paper and set aside.

- In a small mixing bowl with clean beaters, beat egg whites on medium speed until soft peaks form. Gradually beat in remaining sugar, 1 tablespoon at a time, on high until stiff peaks form. Gradually fold into batter. Spread evenly into prepared pan.
- Bake at 375° for 12-15 minutes or until cake springs back when lightly touched. Cool for 5 minutes. Turn cake onto a kitchen towel dusted with baking cocoa. Gently peel off waxed paper. Roll up cake in the towel jelly-roll style, starting with a short side. Cool completely on a wire rack.
- For filling, in a small mixing bowl, beat cream and confectioners' sugar until stiff peaks form. Beat in vanilla. Fold in hazelnuts and chocolate. Unroll cake; spread filling evenly over cake to within 1/2 in. of edges. Roll up again. Place seam side down on a serving platter. Cover and refrigerate for 1 hour. Just before serving, dust with confectioners' sugar. Refrigerate leftovers. Yield: 10 servings.
