Crumble the pumpernickel very finely (preferably with the moulinette). Grate the chocolate finely and mix with the pumpernickel. Mix in a GOOD shot of rum.
Mix 1 packet of pudding powder with a little cherry juice, bring the cherries to the boil WITH the remaining juice and thicken with the mixed pudding powder.
Mix the quark with a little vanilla sugar until smooth.
Prepare the remaining 2 packs of vanilla pudding with milk and sugar according to the instructions on the packet and allow to cool.
Layer all the prepared ingredients in a high bowl. A glass bowl would be best so that you can see the individual layers nicely.
The 1st layer is quark, then follow: 2. Pumpernickel mixture, 3. Cherries 4. Vanilla pudding 5. Pumpernickel mixture, 6. Quark 7. Cherries 8. Vanilla pudding quark again as the last layer on top. Decorate it with a few cherries.
In any case, let the quark sit in the fridge for one night!
