For the vanilla crescents, quickly knead all the ingredients for the dough together into a dough and let rest in the refrigerator for at least 30 minutes.
Roll the dough into finger-thick noodles, cut into pieces and shape them into crescents.
Bake the vanilla crescents in the preheated oven at 210 °C for 10-12 minutes and sprinkle with powdered sugar mixed with vanilla sugar when slightly cooled.
