The McDonald’s McFlurry has been fundamentally redesigned.

On September 4, the fast-food chain announced that it would be doing away with the frozen treat’s plastic lid and instead introducing a “four-flap” cup. The new packaging is designed to further McDonald’s efforts to become more sustainable and environmentally friendly and will be rolled out to restaurants nationwide starting September 10.

The burger brand also announced that the McFlurry will now be available in a mini size in addition to the regular size.

“The Mini McFlurry will be available at participating U.S. restaurants nationwide and will be available on the McDonald’s app and through McDelivery beginning September 10,” McDonald’s USA said in a statement.

“Do you have a friend who always wants ‘just a bite’? Instead of taking an extra scoop, you can get them their own Mini McFlurry. Or maybe you’re looking for a quick afternoon pick-me-up… the Mini McFlurry is perfect for you, too,” the statement continued.

The new McFlurry portion size will also be available in the company’s new packaging.

In October 2023, McDonald’s eliminated its McFlurry spoons. For many customers, the utensil was a point of confusion, as some often mistook its hollow shape for a straw. Instead, it simply served as a spindle for pouring and stirring in sweet toppings.

McFlurry’s new spoon design features a “smaller black spoon that uses less plastic,” a statement said at the time.

McDonald’s said the “small change will help reduce plastic waste when using single-use items.”

In July, the brand introduced an innovative McFlurry flavor: the KitKat Banana Split. The limited-edition treat was packed with candy, featuring vanilla soft serve, real banana chunks, strawberry clusters and KitKat pieces.

In May, the home of the Big Mac launched the Grandma McFlurry, which featured “delicious syrup,” crunchy candy pieces (“like Grandma’s favorite snack that she hid in her purse!”) and vanilla soft serve. The Grandma McFlurry was meant to be “sweet – just like Grandma,” the company said.

New McFlurry flavors have emerged over the years, including the Strawberry Shortcake McFlurry in April 2023 and the Peanut Butter Crunch McFlurry in August 2023.
