M&M's Introduces Walmart-Exclusive Mint Crunchy Cookie Flavor for September 2026 Launch

What Makes This Mint Crunchy Cookie M&M Different

M&M's is set to release a new Walmart-exclusive flavor called Mint Crunchy Cookie in September 2026, offering fans a fresh twist ahead of the holiday season. The candy combines a mint-flavored chocolate coating with a crunchy cookie center, aiming to satisfy cravings for Thin Mints-like treats. Tasting Table's Julia Duda sampled the product early and shared her impressions in an August 2026 report.

The new flavor features a dual-texture design: a smooth mint chocolate shell encasing a crisp, cookie-flavored interior. Unlike standard M&M's, this version leans into a seasonal profile with its cool mint notes and baked-good inspiration. Duda noted the balance between the refreshing mint and the sweet, crunchy center avoids being overly sugary. The product is positioned as a limited-time offering, though exact availability dates beyond September have not been disclosed. Walmart's exclusive distribution means the flavor will not appear in other retail chains initially.

How Does It Compare to Classic Thin Mints

While not an official Girl Scouts collaboration, the Mint Crunchy Cookie M&M draws clear parallels to the beloved Thin Mints cookie in both flavor and timing. The mint-chocolate combination targets similar consumer preferences, especially during fall and winter months. Duda observed that the cookie crunch adds a textural element absent in the smoother Thin Mints, potentially broadening appeal. M&M's has a history of releasing holiday-adjacent flavors, and this launch continues that strategy of tapping into nostalgic taste profiles. The brand has not confirmed whether the flavor will return annually.

Will the Mint Crunchy Cookie M&M be available outside Walmart? No, the flavor is exclusively sold at Walmart stores and online for its initial release, with no current plans for broader distribution.
