50 years ago Richard Nixon was president, M*A*S*H was a movie, and that was the year that McDonald’s gave birth to the Shamrock Shake in just a few locations in the U.S. I know it’s hard to image that not every location carried this green delicious minty treasure. Earlier this week McDonald’s announced that not only are they bringing these yummy shakes back to locations earlier than normal. Expect to see them starting Wednesday, February 19th. They are actually stepping up their game with adding a new product to celebrate the milestone year. Oreo Shamrock McFlurry. This is not the first time they have added a new twist to our favorite treat . They have done a Shamrock Sundae in the 80’s then did a Chocolate Shamrock Shake in 2017.
