Tiramisu is not chocolate http://www.heavenlytiramisu.com/whatisit.htm I think you are tlaking about biscottis. They are a small wafer with chocolate coating on top, hope this helps.

Here is a recipe for Italian Chocolate Mousse that may be what you are looking for. Ingredients: 1 lb. semisweet chocolate cut into small chunks, or chocolate chips 6 eggs, preferably pasteurized (see note below) 2 cups whipping cream Preparation: Preheat the oven to 200 degrees. Put chocolate pieces into a large oven proof bowl and place in the oven until chocolate has melted, 5 to 6 minutes. Remove from oven and set aside to cool slightly. Beat the eggs until foamy in a medium bowl. Add eggs a little at a time to cooled chocolate, beating at low speed. (Do not over beat or chocolate will tighten up) Beat cream until stiff in a medium bowl. Fold whipped cream into chocolate mixture. Spoon mousse into a large glass bowl or into individual glasses. Refrigerate several hours or overnight. Just before serving you can decorate the mousse with additional whipped cream, chocolate shavings or fresh berries. Serves 8 to 10 Note: Anyone with a compromised immune system, including children, the elderly or anyone with a serious illness, should not eat raw eggs because of the possibility of salmonella poisoning. In that case look for pasteurized eggs that are available in some markets.
