Mix egg, milk, flour, liqueur and sugar to a smooth dough. Let dough rest for 20-30 minutes. In the meantime, roast the almonds in a pan without fat while turning them until golden brown, remove them.
Heat the oil in portions in a coated pan and bake 6 golden-brown crêpes from the dough, one after the other.
Spread each crêpe with 1 tablespoon of nut nougat cream and sprinkle with almonds, except for a few for decoration. Roll up the crêpes and cut them in half. Arrange, sprinkle with remaining almonds and dust with icing sugar.
