Prepare a dough from all the ingredients and let it rest for a few hours (preferably overnight) in a cool place (refrigerator, rather a vegetable crisper).
Form the dough into crescents, place on a baking sheet lined with baking paper and bake at 160 ° C for about 15 minutes.
While still warm, sprinkle the pumpkin seed crescents with the sugar-vanilla sugar mixture and shake on paper or roll in it.
