Capitalize on an unexpected +69% spike in Chips Ahoy! unit sales during summer 2023—driven by a viral homemade ice cream sandwich trend—to drive similar year-over-year growth in 2024, despite the fleeting nature of social media trends and declining cookie category sales.
The insight that younger consumers weren’t driven by nostalgia but by their love for creating bespoke treats inspired us to design a campaign that celebrated personalization and creativity.
Leverage AI technology to create the Chips Ahoy! Scanwich experience—a playful, interactive microsite where users could scan any ice cream container to unlock savings on Chips Ahoy! cookies and access inspiration for DIY ice cream sandwiches. The campaign extended across digital, out-of-home, and in-store touchpoints to ensure maximum engagement.
