Knead the flour, 1 packet of vanilla sugar, sugar, butter in pieces and almonds to a smooth dough. Wrap dough in cling film and chill for about 1 hour.
Take the dough out of the refrigerator and form small balls (approx. 2.5 cm Ø) from it. Place the vanilla crescent balls on a baking tray lined with baking paper and bake in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: see manufacturer) for approx. 20-25 minutes until golden brown.
Mix 1 packet of vanilla sugar with icing sugar and roll the finished, still warm balls in it.
