Mix the quark, milk and sugar together. Melt the chocolate in a double boiler and add to the quark. Whip the cream with the vanilla sugar until stiff and fold in. Cut the kiwis into small pieces and fold into the mass.
Decorate the quark dish with kiwi and sprinkles.
The enzymes found in fresh kiwi fruit make dairy products bitter. Therefore, consume the dessert immediately after preparation or add the kiwi just before consumption.
The dessert also goes with other types of chocolate and fruit. If you like, you can add a splash of lemon.
