Shortcut
Instead of spooning remaining Cool Whip onto desserts for the ghosts, use a resealable plastic bag to form the ghosts. Just spoon the Cool Whip into resealable plastic bag. Cut off one corner from bottom of bag, then squeeze Cool Whip from bottom of bag to create the ghosts.
Variation
Instead of topping each dessert with a ghost, top each with a tombstone. Prepare desserts, omitting the remaining 1 cup Cool Whip and the chocolate chips. Decorate 14 Social Tea Biscuits with icing gel to resemble tombstones. Then, insert one in top of each dessert just before serving.
Make Ahead
Desserts can be made ahead of time. Cover and refrigerate until ready to serve.
