For the Krampus muffins, prepare any muffins and pipe small dots (with star nozzle) with whipped cream.
Form small horns from red colored marzipan and attach to the top left and right. In addition, form a small ball, flatten it, score it slightly in the center and attach it as a tongue.
Form small balls (eyes) from yellow colored marzipan and attach. Possibly with chocolate icing still attach small dots and ready are the Krampusmuffins.
