Once the dough is ready, let it rest for 15-20 minutes.
Sprinkle flour on the table and roll out the dough into a rectangle of approx. 60 x 30 cm.
Spread the filling on the dough - all the way to the edge. It is easiest with a knife with a long blade.
Fold one-third of the dough from the short side in over the rest of the dough.
Fold the last third from the opposite side in over so you now have dough and remonce in three layers.
Roll out the dough again to a square of approx. 30 x 30 cm, or so you have approx. 2 cm in thickness.
Cut strips of approx. 2½ x 30 cm.
Rotate each strip by holding one end with one hand and twisting the strip with the other hand so that the strip is twisted. Turn a 6-7 turns.
Place the twisted strip a few times around your index and middle finger on one hand, and place the dough over the dough and in between your index and middle fingers, and pull it with your fingers down between your fingers so that the dough comes into the spin.
Place the cinnamon roll on a baking sheet lined with parchment paper. There must be plenty of space between them.
