Wendy's last week announced it would soon be offering the Thin Mints Frosty. Here's when the dessert will be available in restaurants.

A new Frosty flavor inspired by Thin Mints, the famous Girl Scout cookie, will be available at Wendy's starting in February.

Last week the fast-food chain unveiled the Thin Mints Frosty, which the fast-food restaurant says combines the flavor profiles of two "iconic fan favorites" for a delectable and minty treat.
