For the Linzer eyes, quickly mix the flour with the remaining ingredients to form a dough and chill for half an hour. Preheat the oven (180°C hot air).
Roll out the dough on a floured surface to a thickness of approx. 2-3 mm and cut out circles (approx. 5 cm in diameter). Cut out three “eyes” from each half of the circles. It is best to use the original “Linzer cutter” for this.
Place the discs on a baking tray (lined with baking paper) and bake in the oven on the middle shelf for 10-12 minutes until light brown. After a short time of cooling, put a heap of jam on the unperforated slices, sprinkle the perforated slices with (vanilla) sugar mixture and put two of them together.
The jam should “squeeze” out of the holes a little. Let the finished Linzer eyes dry for another 1-2 hours on a wire rack.
