The Shamrock Shake is a milkshake made with vanilla soft-serve ice cream, artificially flavored minty green syrup and whipped topping. McDonald's debuted the first Shamrock Shake in 1970, and the cult classic has been returning to the menu around St. Patrick's Day each year since.

Dairy Queen has a Mint Oreo Blizzard to get fans in the St. Patrick’s Day spirit. Customers are in luck because the dessert is available now so they have more than a month of green sweets ahead of the holiday on March 17. The Blizzard combines vanilla soft serve, Oreo pieces and “cool mint topping,” per a press release.

All hail the cool, minty McDonald's dessert known as the Shamrock Shake. Here is when it is released for 2025, and for how long it is available.
