McDonald’s brought back a fan favorite this week…
The chain announced that the Shamrock Shake and OREO Shamrock McFlurry are returning to stores nationwide.

The Shamrock Shake was first introduced in 1970 and is made with vanilla soft serve and Shamrock Shake syrup topped with whipped cream.

The OREO Shamrock McFlurry was not created until 2020 and is essentially the Shamrock Shake blended with crushed OREO cookies.
