Ingredients

Cake
½     cup (125 mL) butter
1¼    cup (275 mL) sugar
2     cups (500 mL) flour
3     tsp (15 mL) baking powder
1     tsp (5 mL) salt
1    cup (225 mL) milk
3     egg whites
3     squares semi-sweet chocolate, grated
2     tsp (10 mL) vanilla

Icing
3     egg yolks
2     cups (500 mL) icing sugar
½     cup (125 mL) butter
2    tsp (10 mL) vanilla
3     squares semi-sweet chocolate

Preparation

Beat butter and 1 cup (225 mL) sugar until light and fluffy. In a separate bowl, mix flour, baking powder and salt together; add to butter mixture and mix well. Add milk gradually.

In another bowl, beat egg whites with remaining ¼ cup (50 mL) sugar, and fold gently into mixture; add grated chocolate, and vanilla.

Grease two 9×9-inch (23×23-cm) round cake pans and line with parchment paper. Pour cake batter evenly between the pans and bake at 350ºF (180ºC) for 25-30 minutes. Let cake cool.

To make icing: mix yolks, sugar, butter and vanilla until fluffy. Spread icing on one cake layer; place second layer on top, and spread icing over top and sides.

Melt chocolate and drizzle over icing. Use the tines of a fork to make squiggly lines, giving the impression of ski marks in snow.
