This recipe is enough for about 40 to 60 pieces depending on the size!
Knead all ingredients except the jam, vanilla sugar and icing sugar into a smooth dough and leave to rest in a cool place for about 1 hour.
Roll out the dough (about 3 to 4mm thick).
Cut out the biscuits, half of them with a hole (or several) and place on the baking sheet.
Now put the baking sheet, which may have been lined with parchment paper (not greasing, as the dough contains a lot of butter) with the biscuits into the oven preheated to 170 ° and bake until golden.
After cooling, coat the perforated biscuits with apricot jam and glue the perforated biscuits on top. Sprinkle with a mixture of vanilla sugar and icing sugar.
