Wendy’s new Frosty is a nod to a classic Girl Scout cookie flavor.

The fast food chain has unveiled the Thin Mints Frosty, which the company says combines the flavor profiles of two “iconic fan favorites” for a delectable and minty treat, reports USA TODAY.

The specialty flavor will be available at Wendy’s restaurants nationwide beginning Friday, Feb. 21 for a limited time or while supplies last. Customers can get the Thin Mints-inspired swirl in a vanilla or chocolate Frosty.

“Plus, everyone knows Thin Mints are extra delicious when frozen,” Wendy’s said in a news release, reports USA TODAY. “Each bite pairs minty-chocolatey, crumbly, cookie butter texture with the cool, creamy Frosty.”

According to TODAY.com, the Thin Mints Frosty is swirled with Thin Mints cookie flavor that the brands describe as “minty-chocolatey” and is finished with a crumbly, cookie butter-esque topping.
