McDonald’s Bringing Back Its Beloved Shamrock Shake For a Limited Time – Starting From Today!

Today, McDonald's brings back its iconic Shamrock Shake, marking the unofficial start of spring for many fans. This seasonal favorite, known for its creamy vanilla soft serve blended with minty syrup and topped with whipped cream, has been a staple since its nationwide debut in 1970. Available from today, February 10 through March 23, the Shamrock Shake offers a nostalgic treat for those craving its signature minty flavor.

Adding a sprinkle of nostalgia, McDonald's is reintroducing Uncle O'Grimacey, a character who first appeared in 1975 but has been absent for decades. This green, fuzzy uncle of Grimace hails from "Sham Rock, Ireland," and his return is stirring up both excitement and curiosity among fans. Some are thrilled to see this blast from the past, while others are scratching their heads, wondering, "Who is this green guy?"

Beyond the minty delight, each Shamrock Shake sold will contribute $0.25 to the Ronald McDonald House Charities (RMHC) from February 10 through March 23. This initiative supports families in need, making your indulgence a little sweeter. Additionally, McDonald's is releasing exclusive Uncle O'Grimacey merchandise, with proceeds benefiting RMHC, allowing fans to wear their nostalgia on their sleeves—literally.

As McDonald's rolls out its Shamrock Shake, competitors are also vying for a piece of the minty pie. Dairy Queen, for instance, has introduced a Mint Oreo Blizzard, blending vanilla soft serve with Oreo pieces and mint topping, available through March 17. The fast-food landscape is turning green as chains compete to offer the most enticing seasonal treats.
