Take the dough out of the refrigerator about 20 minutes before processing. Knead the dough briefly and form it into a roll (approx. 3 cm Ø) on a floured work surface. Cut the roll into slices and shape them into croissants. Place the croissants immediately on 2 baking trays lined with baking paper (not too close together).
Bake the trays one after the other in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 8-10 minutes (light brown). Mix sugar and cinnamon. Remove the croissant from the oven, allow to cool for 2-3 minutes, then turn in the sugar-cinnamon mixture. Let the biscuits cool down
