The dessert features a Vanilla or Chocolate Frosty topped with Ghiradelli Chocolate Sauce and Chocolate Chunk Cookie pieces for a suggested price of $1.99. It's basically a combination of the two regular menu desserts that Wendy's offers--their signature Frosty and cookies.
You can find my previous review of the Frosty Cookie Sundae here. It was first introduced in April of last year.
