CHIPS AHOY! is rolling out a new limited-time Mystery Cookie that invites fans to guess its secret flavor for a chance to win a $25,000 grand prize.
The new cookie arrives first through the SnackWorks TikTok Shop starting July 30, while supplies last. A nationwide rollout at participating retailers begins August 10.
The packaging keeps the flavor under wraps with a mystery cookie image and a QR code that sends fans to the official sweepstakes. You can also enter by visiting CHIPSAHOYMystery.com. According to the official rules, you don't have to guess the flavor correctly to receive an entry.
CHIPS AHOY! plans to reveal the Mystery Cookie flavor on Halloween. Until then, the brand says it will share clues across its social media channels as fans try to solve the mystery.
The sweepstakes runs through October 31, 2026, and also includes additional prizes beyond the $25,000 grand prize. No purchase is necessary to enter. The promotion is open to eligible U.S. residents, including Washington, D.C., and Puerto Rico. See the official rules for complete eligibility details.
