For the nut filling, finely grate the marzipan. Knead with nuts, cinnamon, 45 g sugar and eggs. For the quark and oil dough, mix 2 egg yolks with milk, oil, quark, 75 g sugar and salt until smooth. Mix flour with baking powder, sieve onto the quark mixture. Knead to a smooth dough with the dough hooks of the hand mixer.
Roll out to a rectangle (approx. 40 x 28 cm) on a floured work surface. Cut 8 smaller rectangles (approx. 14 x 10 cm) from this rectangle. Put some nut mixture on each of the dough pieces. Whisk 1 egg yolk with cream, brush the edges of the dough with it. Fold over to form a pocket and press down well. Cut the longer side several times about 1 cm. Place combs on 2 baking trays lined with baking paper. Brush with the remaining egg yolk and sprinkle with sliced hazelnuts. Bake the trays one after the other in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 20-25 minutes.

Whipped cream tastes good with it
