Chain: McDonald's
Introduced: 1997

If there's one reason to stop into  McDonald's mid-summer, it's not a Big Mac or a 20-piece McNuggets but something off their menu of frozen treats, my friend. McDonald's frozen treats are on point. The McFlurry with Oreo Cookies is packed with little bits of Oreo cookiesjust enough to introduce some variety into the sweet vanilla soft serve. Always go for the Oreo. M&M McFlurries are for noobs.
