McDonald’s is once again spinning its original fan-favorite Shamrock Shake at participating locations.

The Shamrock Shake is made with the chain’s vanilla soft serve blended with Shamrock Shake syrup and finished with a whipped topping.

The seasonal menu item first debuted on McDonald’s menus back in 1970. You can find it at participating US locations nationwide for a limited time through March 24, 2019, while supplies last.

You can check if the Shamrock Shake is available in your area with this Shamrock Shake Finder.
