Put flour, ##almonds##, 90 g sugar, 1 pinch of salt and butter in flakes in a mixing bowl. Knead first with the dough hooks of the hand mixer, then with your hands to a smooth dough.
Wrap in foil and chill for about 1 hour.
Line three baking trays with baking paper. Preheat oven (electric cooker: 175 °C/circulating air: 150 °C/gas: level 2). Form the dough into 3-4 rolls (approx. 1.5 cm Ø). Cut each roll into 5 cm long pieces and shape into croissants.
Place on the baking trays. Bake in the oven for 13-15 minutes one after the other.
Mix 75 g sugar and vanilla sugar on a plate. Take the croissants out of the oven and roll them immediately in the sugar. Let them cool down.
