Prepare cake as directed on box using one third cup Amaretto in place of water in directions. Bake in 2, 20 cm greased cake pans, following package directions. Cool in pans 10 minutes. Remove and continue to cool on racks. Even tops if necessary. In a chilled deep bowl, beat cream, confectioner's sugar until almost stiff, add quarter cup Amaretto and beat until stiff. Place one layer on serving plate and spread with 1 cup of cream mixture. Top with second layer and frost. Chill 4 hours. Melt chocolate morsels over hot water until smooth. Spread in a 1 cm thick layer on foil and chill until firm enough to cut. With different size cookie cutters cut out trees from the chocolate. If you don't have a tree cutter you can make a pattern on cardboard, cut it out and trace onto chocolate. Decorate top of cake with trees or you can place trees the same size over the sides of the cake and spinkle top with green sugar. It is best to add the trees just before serving so that they will not melt. ----
