Once the new Frosty desserts launch this spring, head to your nearest Michigan Wendy's to grab a taste. The fast-food chain features dozens of restaurants throughout the state. Frosty Swirls are a choice of chocolate or vanilla Frosty swirled with a choice of delicious sauce, Wendy's said.

In honor of National Girl Scout Day on March 12 and St. Patrick's Day on March 17, Wendy's is offering free Thin Mints Frostys and Fries this week, respectively. Customers can grab the deals through the Wendy's app or website.

Seeing our iconic Thin Mints paired with Wendy’s Frosty is a testament to the power of the Cookie Program and millions of Girl Scouts who have made Thin Mints so popular,”

Wendy's announced at its Investor Day last week it will be introducing two new Frosty varieties to its menu this spring.
