For the Frankfurt nut pastry, quickly knead all ingredients together to form a dough. Wrap this in plastic wrap and place in the refrigerator overnight.
Roll out the dough on a lightly floured work surface, cut out cookies, place on a baking tray lined with baking paper and brush with a beaten egg.
Bake the Frankfurt nut cookies over medium heat.
Preparation Tip:
If you like, you can decorate the Frankfurter Nussgebäck with icing.
