Those nifty individual spongecakes or ladyfingers (my favorite) are awesome to keep in the freezer, with all the fab berries currently available. Skip the custard/pudding and use fat-free Cool Whip. Crush a few nuts or chocolaty cookies and somewhat layer ingredients in pretty glasses. Go to hell with yourself, 'cause this dessert is legal! Spike it with a touch of apricot brandy, or whatever.
