The Shamrock Shake Is Officially Back on the McDonald’s Menu

We know that old song says that Christmas is “the most wonderful time of the year,” but Shamrock Shake season has to be a close second. Yes, everyone, the pastel-hued beverage is back on McDonald’s menus everywhere.

According to the fast food giant, the shake was created in 1967 by Hal Rosen, a Connecticut McDonald’s owner and operator. It debuted nationally in 1970 and was an instant success across the country.

The frozen treat made its annual debut on Monday, February 20, and will be available at participating restaurants nationwide for a limited time. (McDonald’s hasn’t said exactly how long “a limited time” lasts, but it will likely stick around through St. Patrick’s Day.)
