The Shamrock Shake—along with an old friend—is back at McDonald’s
The Shamrock Shake, a creamy vanilla soft-serve blended with minty green syrup and topped with whipped cream, has been a fan-favorite since 1970. And for those who like a little crunch with their nostalgia, the Oreo Shamrock McFlurry—featuring crushed Oreo pieces mixed into that same minty goodness—is making a comeback too.
