Put the room-temperature butter, cottage cheese, sugar, vanilla sugar and a pinch of salt into a bowl. Mash and rub together with a spatula or fork.
Sift in the flour with the baking powder in two additions and knead the dough. Put it in a bag and refrigerate for 30 minutes.
Divide the dough into 2 pieces and roll each one out thin into a rectangular sheet, sprinkling with cinnamon if you like.
Cut the sheet into strips about 3 cm wide and roll each one into a spiral. Place on parchment.
Bake for 30 minutes in a well-preheated oven at 180 C. Enjoy!
