Chocolate Yule Log

DIRECTIONS

1. Line a 15-in. x 10-in. x 1-in. baking pan with parchment paper; grease the paper. Place egg whites in a small mixing bowl; let stand at room temperature for 30 minutes. In a large mixing bowl, beat egg yolks on high until light and fluffy. Gradually add 1/2 cup sugar, beating until thick and lemon-colored. Combine flour, cocoa and salt; gradually add to egg yolk mixture until blended.
2. Beat egg whites on medium until foamy. Add cream of tartar; beat until soft peaks form. Gradually add remaining sugar, beating on high until stiff peaks form. Stir a fourth into chocolate mixture. Fold in remaining egg whites until no streaks remain.
3. Spread batter evenly in prepared pan. Bake at 350 degrees F for 12-15 minutes or until cake springs back (do not overbake). Cool for 5 minutes; invert onto a linen towel dusted with confectioners' sugar. Peel off parchment paper. Roll up in the towel, starting with a short side. Cool on a wire rack. In a mixing bowl, beat cream until it begins to thicken. Add sugar and coffee granules. Beat until stiff peaks form; chill. Unroll cooled cake; spread filling to within 1/2 in. of edges. Roll up again. Place on serving platter; chill.
4. In a mixing bowl, beat frosting ingredients until smooth. Frost cake. Using a fork, make lines resembling tree bark.
