McDonald's has a new McFlurry: Peanut Butter Crunch flavor is out now

If you've been able to recover from McDonald's purple Grimace shakes, the fast-food chain has a new sweet treat available for a limited time.

Just try not to pass out this time for a viral TikTok trend, OK?

The Peanut Butter Crunch McFlurry debuted Wednesday at participating locations nationwide. The dessert is made with vanilla soft serve and blended with crispy cereal mix and chunks of chocolatey peanut butter cookie.

The treat, which has 510 calories for a regular size, is available while supplies last, McDonald's said.

What other desserts had McDonald's introduced this year?

The new McFlurry flavor is the latest dessert that McDonald's has introduced this year as it continues to test new products.

In March, the chain debuted a Strawberry Shortcake McFlurry that temporarily joined its other classic McFlurry flavors, like Oreo and M&M.

And in June, McDonald's celebrated the birthday of its classic character Grimace with a limited-edition Grimace Birthday Meal, and of course, the now-infamous purple berry-flavored shake.

It wasn't long until the shake sparked a viral trend on TikTok in which users posted videos pretending to pass out — or worse — in a purple puddle after consuming the treat.
