Cake
1/2 cup sifted flour
1/4 cup unsweetened cocoa powder
1 teaspoon baking powder
1/4 teaspoon salt
1/2 cup sugar
3 eggs, separated
1/4 cup milk
For Rolling
1/8 cup icing sugar

1 1/2 cups whipping cream, whipped with
1 tablespoon sugar
For Icing
2 cups heavy cream
8 ounces semi-sweet chocolate baking squares, melted
1/4 cup butter, softened
For Decoration
1/8 cup icing sugar
colour food coloring (I do red and green)
8 ounces marzipan, divided

Preparation

Preheat oven to 350 degrees F.
Grease a 15 X 10\" jelly roll pan. Line with a sheet of waxed paper. Grease paper as well.
Sift together the flour, cocoa, baking powder and salt.
In separte bowl, beat together sugar and egg yolks. Alternate adding the milk and the flour mixture into the egg and sugar mix.
In another separtate bowl, using clean mixer blades, beat egg whites until stiff but not dried out. Fold one third of the egg whites into the other mixture. Then carefully fold in remaining egg whites.
Spread batter into pan, smooth out the top.
Bake for 12 minutes, or until set.
While waiting for cake to cook, prepare whipping cream. Beat whipping cream with 1 tablespoon sugar until thick. Set aside in the fridge.
When cake is done, remove from oven. Dust a clean tea towel with icing sugar. Turn cake out onto this. Remove waxed paper. Cut edges of cake to make a nice even looking rectangle. Starting with the short side, roll the cake up jelly-roll style. Transfer seam side down to a rack for cooling. (30 minutes).
While cake is cooling, prepare icing:
In a small pot, bring cream, melted chocolate and butter to a low boil over medium low heat. Stir vigorously until blended. Remove from heat and let stand.
On a flat surface dusted with remaining icing sugar, knead food colouring into each piece of marzipan, (as many colours as you'd like)until well blended.
Unroll the now cooled cake and spread the whipped cream over it to with 1 inch of all sides. Re-roll cake. Place seam side down on serving dish.
Spread icing over top and sides and ends of cake.
Roll out marzipam with a rolling pin and cut into various shapes with cookie cutters or a knife. Arrange on cake. Sift a small amount of icing sugar on completed cake to make it looked like a light dusting of snow.
