Stir the room-warm QimiQ in a bowl until smooth. Mix with quark and sugar or sweetener. Roughly chop the chocolate in the mixer or grate it roughly with a grater and stir into the cream.
Arrange in bowls or glasses and let set in the refrigerator for 1 - 2 hours. Sprinkle with cocoa powder just before serving.
Tip: Chop the chocolate into pieces of different sizes. Not only does it look better, it also gives the cream that certain bite.
Additional info: QimiQ consists of single cream and 1.5% gelatine. You can also just use cream, but it won`t be that firm. If you want, you can of course also use cream and gelatine.
