Put the quark with the natural yoghurt, the sugar and the vanilla sugar in a medium-sized bowl and mix everything with the whisk to a smooth mass.
Carefully wash and quarter the strawberries. Cut the chocolate bars into small pieces and add to the curd mixture with the strawberries. Mix everything with a tablespoon.
Pour the strawberry quark cream into small glass bowls or dessert glasses and sprinkle with chocolate sprinkles as desired.
