Wendy’s is transforming its beloved Frosty lineup into an even more delightful experience. This spring, the fast-food giant is set to unveil innovative offerings: Frosty Swirls and Frosty Fusions. These new additions will empower customers to craft their own unique Frostys by mixing and matching an array of sauces and toppings.
Fans of Wendy’s have yet another reason to rejoice. On March 12, 2025, in celebration of National Girl Scout Day, Wendy’s will be giving away free Thin Mints Frostys all day long.
Discover the Wendy’s Thin Mints Frosty
The Thin Mints Frosty is a delectable creation inspired by the iconic Girl Scout Thin Mints Cookies. Unlike previous seasonal flavors that were eventually supplanted by the classic Vanilla Frosty, this treat is fully customizable, allowing customers to top either a chocolate or vanilla Frosty with delicious Thin Mints cookie butter.
This latest offering provides a smooth, rich blend of the classic Frosty, complemented by the delightful crunch of Thin Mints cookie butter.
