Extravagant presentation features creamy dark chocolate and white chocolate mousse floating between layers of marbled white and dark chocolate cake. A glaze of dark chocolate ganache swirled with white chocolate coating tops it off in a truly decadent fashion.
Thaw and serve. For best presentation and results, cut cake while still partially frozen. Wrap and return any unused cake to the freezer while still frozen. Thaw cut portions in the refrigerator. For maximum flavour, let refrigerated portions stand at room temperature for 15 to 20 minutes before serving.
