Frozen Jack O'Lanterns are easy to make for Halloween and taste delicious:
1 tub of dark chocolate or fudge ice cream
24 whole cinnamon sticks
Cut off the top of the oranges and gently hollow out the pulp, leaving a thick shell; hollow pulp out of cut-off tops too. Carefully cut Jack-O'Lantern faces into each orange. Freeze hollowed shells for at least 1 hour.
Place scoops of ice cream into frozen shells, avoiding letting the ice cream ooze out of eyes or mouth. Cut a small hole in the top of each orange. Set tops back on over the ice cream and insert a cinnamon-stick stem through the hole. Freeze for at least 3 hours or until serving time.
