Cold Stone Creamery lets you be the creative guru by mixing any flavors of ice cream they make in house each day, with any combination of snacks from cookies to candy bars and flavored chips (chocolate, peanut butter, etc) to nuts. They have anything you'd ever want in an ice cream treat and more. Downside? It's tough to choose a combination given all the choices you have available, but they always let you sample the ice cream too. And if you don't "love it" (one of their sizes of cups) they'll let you make another creation free of charge.
