Knead 250 g flour, sugar, vanilla sugar, 1 pinch of salt, 1 egg, almonds and butter in pieces first with the dough hooks of the mixer and then briefly with your hands to a smooth dough. Cover and chill for about 30 minutes.
Preheat oven (electric cooker: 200 °C/circulating air: 175 °C/gas: see manufacturer). Line a baking tray with baking paper. Roll out the dough on a little flour to a thickness of about 1 cm. Cut out 8 circles (approx. 9 cm Ø), knead the dough again, roll out and cut out further.
Place on the baking tray.
Separate two eggs. Chill the egg whites. Whisk egg yolk and 2 tbsp. water. Spread dough circles with it. Bake in hot oven for 12-15 minutes. Let them cool down.
Mix icing sugar, egg white and lemon juice with the whisks of the mixer. For the head, stick 1 jelly bean as a nose on each marshmallow with a little bit of icing. Paint eyes and mouths on the marshmallows with sugar writing.
Coat the biscuits loosely with the icing. Immediately place 1 marshmallow head on each edge. Stick chocolate lentils as buttons on them. Press cookie sticks into the icing as broomsticks. Let everything dry.
