As we get ready to embrace the festivities of St. Patrick’s Day, McDonald’s is bringing back a treat many of us have been waiting for all year.

This time, though, there’s a fun twist that’s bound to surprise fans of all ages.

The beloved Shamrock Shake is back, but with something extra – a special guest who’s made a long-awaited return to the McDonald’s family.


Fans of nostalgia will surely recognize this character, and let’s just say... they’re here to make this year’s Shamrock Shake season even more memorable!

Trust us, it’s the perfect way to make your Shamrock Shake experience even more festive! Stay tuned to discover what’s waiting for you. You won’t want to miss out on this hidden gem!


The Return of a Seasonal Favorite

The Shamrock Shake has been a part of McDonald’s tradition since 1970, bringing together the refreshing taste of mint with the rich creaminess of vanilla soft-serve ice cream.

It’s the perfect treat to mark the arrival of spring. From Monday, February 10, you’ll find this nostalgic favorite at participating McDonald’s locations, ready to be enjoyed once again.


But that’s not all! For those who crave a little crunch in their minty treat, the Oreo Shamrock McFlurry is also back on the menu.

Imagine the classic Shamrock Shake, now blended with Oreo cookie pieces – it’s a heavenly match for the season!


A Sweet Gesture for a Good Cause

McDonald’s isn’t just about satisfying your cravings – they’re also helping make a difference. For every Shamrock Shake sold through March 23, McDonald’s will donate 25 cents to Ronald McDonald House Charities.

This generous contribution helps provide families with a place to stay while their children receive medical care. It’s a small act that can make a big impact, giving you an even sweeter reason to enjoy the treat.


The Legend of Uncle O’Grimacey

Now, here’s the big surprise. The charming Uncle O’Grimacey is back after a long absence! This fun, emerald-green character, who first appeared in 1975, is bringing his Irish flair and jolly spirit to McDonald’s once again.

With his shamrock vest, jaunty hat, and walking cane, Uncle O’Grimacey became the face of the Shamrock Shake for years before retiring with other beloved mascots. This year, McDonald’s is bringing him back to add a special touch to the festivities.


Exclusive Uncle O’Grimacey Merchandise

To celebrate the return of this iconic character, McDonald’s is offering limited-edition Uncle O’Grimacey merchandise. T-shirts, baseball hats, and crewnecks featuring this festive figure are available for purchase on McDonald’s Unlimited website.

And in the spirit of giving, McDonald’s will donate a portion of the proceeds from merchandise sales to Ronald McDonald House Charities.



Calorie Counts to Consider

Before you indulge in these delicious treats, let’s talk about the numbers. A medium Shamrock Shake comes in at 540 calories, while the Oreo Shamrock McFlurry has 460 calories for the regular size.

While these might be a bit of a splurge, they’re well worth it for many fans who look forward to this special time of year.

Whether you're savoring the minty goodness of the Shamrock Shake or indulging in the Oreo McFlurry twist, McDonald's seasonal treats are here to make your St. Patrick's Day celebrations even sweeter.

Don't forget, every sip and bite helps a good cause too. So, what are you waiting for? Head over to your nearest McDonald's and join in the fun!
