Defrost the dough sheets at room temperature. Sprinkle the work surface with 1⁄2 tbsp. sugar. Place 1 plate on top, sprinkle with 1⁄2 tbsp. sugar and roll out slightly larger. Place on a baking tray lined with baking paper.
Process the remaining puff pastry as described above. Bake in the preheated oven (electric oven: 200 °C/circulating air: 175 °C/gas: see manufacturer) for approx. 15 minutes. Remove from the oven and allow to cool.
Break the puff pastry into pieces. Stir cream quark, 200 g sugar and vanilla pulp until smooth. Whip cream until stiff and fold in. Shortly before serving, stir plum puree into the cream so that streaks appear.
Layer the puff pastry alternately with the cream in a large glass bowl.
