Put the flour in a bowl and make a well in the middle. Place the sugar, vanilla sugar, baking powder and butter in flakes on the rim. Put the egg in the middle and knead everything into a smooth dough.
Chill the dough for about 1 hour. Then roll out thinly and cut out cookies with a small flower. Poke three small holes out of half of the cookies with a glass tube.
Place on a baking sheet that has been greased or lined with baking paper.
Bake at 180 ° C for about 10 minutes.
Brush the whole biscuits with red jelly, dust the perforated biscuits with powdered sugar and put the two biscuits together.
