Knead butter in pieces, 75 g icing sugar, flour, egg yolk, cocoa and 1 pinch of salt first with the dough hooks of the hand mixer, then with floured hands to a smooth dough. Wrap in foil and chill for about 30 minutes
Roll out the dough between 2 layers of baking paper 3-4 mm thin. Cut out approx. 50 circles with a round cookie cutter (approx. 3 cm Ø), kneading the dough again and again and cutting out more. Place on 2 baking trays lined with baking paper. Pre-bake one after the other in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 5-10 minutes, remove
Finely chop the cranberries and set aside approx. 1 tbsp for decorating. Beat the egg whites and 1 pinch of salt with the whisk of the hand mixer until very stiff. Gradually add sugar to the mixture to make it shiny and firm. Mix almonds, starch, 85 g icing sugar and cranberries and fold into the beaten egg white. Pour the macaroon mixture into a piping bag with a perforated spout (approx. 1 cm Ø), squirt a dab onto each cookie. Decorate each cookie with 1 piece of cranberry. Reduce oven temperature (electric cooker: 150 °C/ circulating air: 125 °C/ gas: level 1). Bake the biscuits one after the other for another approx. 10 minutes
Waiting time approx. 30 minutes
