EAST HANOVER, N.J., July 30, 2026 /PRNewswire/ — The CHIPS AHOY! brand is turning snack time on its head for cookie lovers across the country with its latest, top-secret product offering: the limited-edition CHIPS AHOY! Mystery Cookie. Designed to be decoded and ultimately devoured, the CHIPS AHOY! Mystery Cookie challenges everything fans think they know about the cookie and tasks them with solving the case.

The packaging was overhauled to feature an unidentifiable cookie wrapped in spooky caution tape, cueing a top-secret flavor. The cookie broke through from another flavor dimension after a glitch occurred and only fans can decode it. The brand’s cookie mascot, Chip, will serve as the ultimate sidekick to help fans crack the case and fix the glitch for good.

“For Gen Z, snacking and gaming aren’t just pastimes, but how they connect, recharge and build community,” said Mili Laddha, Senior Director Marketing, Mondelēz International. “With the CHIPS AHOY! Mystery Cookie, we’re leveling up the snacking experience to match their energy. We’ve turned a simple treat into an interactive side quest, blending IRL flavor with the digital culture they live and breathe.”
