Try this nonalcoholic punch at your next Halloween bash. Since little ghouls and goblins will likely be pumped up on sugar from trick-or-treat bags, this punch made from diet root beer and frozen yogurt won't add to the impact.
2 liters diet root beer
24 gummy worms, plus more if desired
1 pint low-fat vanilla frozen yogurt
1 pint low-fat chocolate frozen yogurt
Arrange the gummy worms in a 12-compartment ice tray, letting them hang out over the edges of the tray. Fill with root beer and freeze at least four hours or overnight.
With a small ice cream scoop, fill the bottom of a one-gallon punch bowl with scoops of both frozen yogurts, using the full container of each. Very slowly fill the punch bowl with root beer, which will foam up to create the "slime."
Float the wormy ice cubes on top of the punch. Fill each punch cup with a scoop of ice cream and an ice cube. Float additional worms on top of the punch or in each glass.
