Mix flour, starch and baking powder and sieve into a bowl. Add butter in small pieces, sugar, vanillin sugar, salt and egg. First knead with the dough hooks of the hand mixer, then with cool hands quickly to a smooth dough. Wrap in foil and chill for about 1 hour. Roll out the dough on the floured work surface to a thickness of 3-4 mm. Cut out angels (about 7 cm long) and place them on 2-3 baking trays lined with baking paper. Bake the trays one after the other in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas cooker: level 2) for about 10 minutes.
Let the pastry cool down on cake racks. Sieve 175 g icing sugar and stir with lemon juice to a glaze. Pour the icing into a small freezer bag and cut off a small corner. Decorate the angel with the icing and sugar pearls. Let it dry. Dust with 1 tbsp. icing sugar
