A limited-time menu featuring a celebrity collaboration is on its way to McDonald’s this holiday season.

On Monday, Dec. 12, McDonald’s will unveil their “Mariah Menu” to celebrate the countdown to Christmas with 12 days of deals on the McDonald’s app, exclusive Mariah Carey x McDonald’s merch and a TV commercial.

“To bring even more holiday cheer to the Mariah Menu, we’re decking out fans and celebrating Mariah’s longtime love of the Golden Arches with exclusive beanies and t-shirts,” McDonald’s announced.

Customers will be able to redeem the Mariah Menu deal — a bakery item and Sausage McMuffin with Egg, respectively — through Mobile Order & Pay with a $1 minimum purchase on Dec. 15 and Dec. 21. The first approximately 10,000 people to order can claim the special merch item for that day.

The beanie, offered Dec. 15, features Carey’s signature, while the t-shirt, offered Dec. 21, includes a throwback photo of Mariah enjoying her go-to McDonald’s order — a cheeseburger with extra pickles.

All 10 McDonald’s on Maui are participating. In order for people to get the deals, they need to download and use the McDonald’s app on their phone, which is free. There’s also a new rewards program they can opt into. 

Daily deals include:

• Dec. 13 — Big Mac
• Dec. 14 — McChicken

“I have such amazing memories with McDonald’s over the years,” Carey said in a press release announcement.

The promotional sale is offered in the United States starting on Dec. 13, featuring a different free item each day with a $1 minimum purchase on the McDonald’s app once per day at participating McDonald’s.
