At locations in more than a dozen states, Rocky Mountain Chocolate Factory delivers more than 40 flavors of frozen yogurt packed with live and active cultures and designed in low-fat, non-fat, and sugar-free varieties. Self-serve machines line the shop’s lime green walls, ready for customers to dispense heaping swirls of old favorites, such as cookies n' cream and fruit sorbet, or seasonal innovations, including eggnog in the winter and fireworks in the summer. Next, patrons head to the toppings bar and crown their frozen treats with as much fresh fruit, cereal, and candy as they can handle before weighing cups and paying by the ounce.
