McDonald's Shamrock <br />Shake to Be Joined by <br />Oreo Shamrock McFlurry It's nearly time for <br />Shamrock Shake season. This year is the <br />St. Patrick's Day-themed <br />item's 50th anniversary. The famous shake will be available nationwide starting February 19. For 2020, McDonald's is <br />introducing another <br />St. Patrick's Day-themed drink, <br />the Oreo Shamrock McFlurry. The move comes after the chain served an <br />Oreo Mint McFlurry in limited locations last fall. Combined with "shamrock flavor," the McFlurry <br />adds oreo pieces to vanilla soft serve ice cream. Just like the regular Shamrock Shake, <br />it is expected to be available for a limited time.
