Whip the whipped cream until stiff and mix with plain yoghurt. Sweeten with icing sugar as desired. Halve the cream and stir the cranberry compote into one half. Fill the dessert glasses half full with it, then pour the rest of the yoghurt cream over them. Stick about 2-3 ladyfingers in each. Finally, add 1 tablespoon egg liqueur per serving. Spread a few chocolate sprinkles over the top to garnish.
