General Mills is teaming up with Dunkin' to introduce three new breakfast cereals inspired by the coffee chain's popular drinks, bringing new flavors to Cinnamon Toast Crunch, Reese's Puffs, and Golden Grahams. The limited-edition collaboration combines some of General Mills' most recognizable cereal brands with flavors inspired by Dunkin's coffee menu, offering a new way to enjoy the taste of the chain's beverages at breakfast. The three cereals are scheduled to arrive in stores in December 2026, with one flavor available exclusively at Walmart.
