The Oreo Shamrock McFlurry features soft served mixed with mint-flavored syrup and Oreo cookie pieces. It's basically an Oreo McFlurry with the addition of the same syrup as a Shamrock Shake, which may make you wonder why they never offered it before.
The returning Shamrock Shake features vanilla soft serve blended with mint-flavored syrup, crowned with whipped topping (shakes used to come with a cherry on top but they've since gotten rid of those).
Both St. Patrick's Day-themed dessert will be available for a limited time only, while supplies last.
