Pour cinnamon stars into a freezer bag. Close the bag. Roll over with a dough roll until the cookies are finely crumbled. Beat the egg whites until stiff and allow the sugar to trickle in. Whip the cream until stiff and carefully fold into the egg whites.
Fold in the cookie crumbs. Pour the mixture to about 3⁄4 into the drinking cups. Stick the ice-stick in the middle. Freeze for at least 6 hours, preferably overnight.
Chop the chocolate coating. Melt with coconut oil in a hot water bath, remove from heat. Remove ice from the moulds. Dip about half each into the chocolate. Freeze again until serving.
