There are countless items on the Wendy’s menu that set it apart from its competitors. From the fresh, never-frozen square beef patties to the beloved chili and Baconator. However, no matter how hard another fast food restaurant tries, it will never replicate Dave Thomas’ Frosty.
The iconic treat is the perfect mixture of a milkshake and soft-serve ice cream that fans have been enjoying since the very first Wendy’s restaurant opened. What started as an only Chocolate offering has soared into new flavor realms with Vanilla, Strawberry, Peppermint, Orange Dreamsicle, and more.
Wendy’s began its Frosty flavor journey a few years ago with the introduction of its Strawberry Frost, which instantly became a fan-favorite. Now, the Columbus, Ohio-based chain is known for changing out its treat offerings for nearly every season.
Recently, Wendy’s took its Frosty to another new level when it introduced the Pineapple Under the Sea Frosty in collaboration with “Spongebob Squarepants.” The Vanilla Frosty featured a first-of-its-kind Pineapple Mango purée swirl, which the brand quickly realized created a whole new way to Frosty.
Now, after weeks of speculation swirling, Allrecipes can exclusively report that Wendy’s is releasing an all-new Thin Mints Frosty made in collaboration with the Girl Scouts.
Wendy's Launches New Thin Mints Frosty

Wendy’s new Thin Mints Frosty is inspired by the Thin Mints cookie flavor, crafted into a minty-chocolatey swirl. The Thin Mints sauce, which adorns the side of the Frosty cup as well as the top of the treat, has a crumbly, cookie butter-esque texture to give you both the taste and iconic crunch of the Girl Scout cookie.
The two nostalgic flavors of Thin Mints and Frosty join forces in both the Chocolate and Vanilla Frosty—meaning, yes, the Vanilla Frosty will stay on the menu for this launch.
To coincide with the 2025 Girl Scout cookie season, Wendy’s new Thin Mints Frosty will hit restaurants nationwide on Feb. 21 for a limited time. I tried Wendy’s Thin Mints Frosty—in both chocolate and vanilla varieties—early at the chain’s Columbus headquarters, here is my honest review.
My Honest Review
Before the social media speculation began, I was brought in on the new flavor launch with only three words: Thin Mints Frosty. I only knew the name and that the Frosty would include a Thin Mints cookie swirl. So, I, like the rest of the internet began wondering what a Thin Mints Frosty would be like.
Would the cookie pieces be in the dessert, like a Blizzard? Would there be a cookie-flavored sauce at the bottom for me to mix into the Frosty? I thought about it for weeks—and let me be the first to say Wendy’s Thin Mints Frosty was even better than I could have imagined.

To start, it’s the first time the flavor is available in both chocolate and vanilla varieties, meaning Wendy’s will technically have four Frosty flavors at once in February. Wendy’s Global VP of Culinary Innovation, John Li, explained that they chose to do both a chocolate and vanilla flavor in hopes that customers will try both—and after I tried both, you absolutely need to.
Typically, I’m a Chocolate Frosty lover through and through (you can’t beat the OG), and the Thin Mints cookie butter adds a double-chocolate element that is extra decadent. Whereas, in the Vanilla Frosty, the Thin Mints cookie butter really has a chance to shine on its own—and shine it does.
The cookie butter is the perfect consistency of smooth chocolate with bits of crunchy texture—exactly like Thin Mints themselves. If you put your Thin Mints in the freezer (a.k.a. the best way to eat them), then you know the extra-crunchy, cold cookie is top tier. Stick those cookie flavors and textures in a minty, chocolatey sauce, add it to a Frosty, and you’ve got the perfect dessert.
Naturally, after shoveling both Frostys into my mouth—with a spoon and fry—I had to know if Wendy’s would bring any other Girl Scout cookie flavors to its treat.
“[We asked the Girl Scouts] which of your iconic treats makes sense,” Li explained. “Easily, it was Thin Mints. They didn’t even have to think twice about it.”
But, Samoa, Tagalong, or Do-Si-Do lovers don’t fear. Li is always thinking ahead to what the next Frosty could be—and maybe a yearly Girl Scout collaboration is part of that seasonal rotation.
For now, however, you’ll want to get the Thin Mints Frosty while you can. No matter your expectations, you really can’t know what it’s like until you try the Thin Mints cookie butter sauce. And, once you do, I’m sure you’ll be asking Wendy’s what's next in its dessert sauce journey, too.
