Mix in a bowl all the ingredients into a smooth dough. Cover and leave it in the fridge for 30 minutes.
Divide the dough in small pieces and roll out with your hands until it is about 3 1/2 inch long. Shape into crescents and place them at least 1/2 inch apart on a baking sheet lined with parchment paper.
Bake for about 10 minutes or until a very light brown.
Mix icing sugar and vanilla sugar, then delicately toss in the hot cookies.
