Roughly chop the chocolate. Cream fat, white and brown sugar, salt and vanilla sugar with the whisk of the hand mixer. First add the egg, then the flour. Mix in the chocolate. Line two baking trays with baking paper. Place 7 large heaps of chocolate on each baking parchment at a good distance from each other and press flatter (6-7 cm Ø). Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see manufacturer) one after the other for 12-15 minutes. Cut hot cookies immediately into 2 half circles with a knife. Let cool down for about 1 hour
Mix the icing sugar and egg white briefly with the whisk of the hand mixer to a smooth, thick icing. Add red and some yellow food colouring to the mixture and colour it red to slightly flesh-coloured
Coat the top of one cookie half with icing. Apply the glaze thickly up to the round edge, becoming thinner towards the cut edge. Now place the marshmallows all around the cookie, close to each other. Spread the other half of the cookie with the icing on the underside in the same way and place on the marshmallows. Press on lightly. Press 2 almond slivers as vampire fangs to the right and left of the two front teeth into the icing. Leave to dry for about 2 hours.
waiting time approx. 2 3/4 hours
