Put half of the crumbles into a greased springform pan (24 cm Ø), press them down to a smooth base and chill. Put the rest of the crumbles in a cool place. For the cheese mixture, stir the quark, mascarpone, 75 g sugar and 1 packet of vanillin sugar until smooth. Stir in 3 eggs and sauce powder one after the other. Spread the cheese mixture on the bottom and smooth it down.
Dab half of the cranberries onto the mixture. Spread the remaining crumbles on the cheese mixture.
