CHICAGO (CNN) McDonald’s Shamrock Shake is back nationally for the first time in three years and it’s also the 50th anniversary of the iconic drink.
According to McDonald’s, the Shamrock Shake was created in 1967 by Hal Rosen, a Connecticut McDonald’s owner/operator who made the delicious, mint shake in celebration of St. Patrick’s Day. It debuted nationally in 1970 and was an instant success across the country.
In 1974, sales from the shake helped to build the very first Ronald McDonald House in Philadelphia. The mission began when the daughter of a Philadelphia Eagles player was being treated for Leukemia. Together with a local McDonald’s owner/operator Hal Rosen, McDonald’s founder Ray Kroc, the Children’s Hospital of Philadelphia and the Philadelphia Eagles, the family raised enough funds through Shamrock Shake sales to help open the first Ronald McDonald House as a way to keep families close during difficult times.
