If you are decorating your own cups, first prep them. You can do this days before as you do not want a fresh coat of permanent marker when you are serving a cold beverage.

First, using the black permanent marker, draw jack o lantern faces on the cups. (Here are some inspiring Jack-o-Lantern Faces.)

When you are ready to serve, place two scoops of vanilla ice cream in each cup.

Pour refrigerated orange soda over the top of the ice cream until the cup is full.

Serve and enjoy!
