The Frosty Cookie Sundae features a chocolate or vanilla frosty topped with Chocolate Chunk Cookie pieces and Ghirardelli Chocolate Sauce.
They're going for $1.79 in my area (may vary).
While these may only be available for a limited time, it's easy enough to buy a cookie at Wendy's and crumble it over a Frosty yourself, although you might have to find some chocolate sauce on your own.
