Mix the soft butter and sugar with a hand mixer until creamy, then stir in the egg. Mix the flour and a pinch of salt and stir in as well. Fold in desiccated coconut and cranberries.
Shape small balls with moistened hands, place on the tray and flatten the dough balls with a moistened teaspoon.
(Only about 12 pieces per tray, as they diverge during baking.)
Bake at 175 ° top-bottom heat for about 15 minutes.
Let cool down briefly, then very carefully remove the cookies from the baking tray, e.g. with the help of a wide knife, and let them cool down completely on a wire rack.
