In a match made in dessert heaven, two of America’s most iconic brands—Reese’s and Oreo—have officially joined forces to launch not just one, but two game-changing treats. After years of fan speculation and DIY mashups circulating online, the collaboration has finally been made real, with both candy and cookie lovers in for something truly indulgent.
The star of this sugary alliance is the brand-new Reese’s Oreo Cup—a peanut butter cup unlike any before. While it keeps the signature creamy peanut butter filling and smooth milk chocolate shell Reese’s is known for, the twist lies in the crunchy Oreo cookie bits mixed into the peanut butter, all topped with a silky white crème layer inspired by Oreo’s iconic center. The result is a layered bite with a crunch and a swirl of flavors that promise to satisfy cravings on both sides of the snack aisle.
Not to be outdone, Oreo is also rolling out its own hybrid: the Oreo Reese’s Cookie. Think classic Oreo sandwich cookie, but instead of the usual white crème filling, it’s been swapped for a peanut butter crème infused with crushed Oreo bits. The mashup is a flavor flip of the Reese’s Oreo Cup and stands on its own as a bold new twist in Oreo’s ever-growing lineup of limited-edition flavors.
While the collaboration marks their first formal partnership in over a decade, it’s hardly unfamiliar territory for snack fans who’ve long demanded a mashup of the two. In fact, social media has buzzed for years with fans creating their own hacked versions of Oreo-stuffed peanut butter cups or Reese’s-filled cookies. Now, both brands have given the green light to what many consider snack royalty.
The Reese’s Oreo Cup is not only launching nationwide this fall—it’s here to stay. Available in Mini, Standard, and King Size formats, the cup will become a permanent member of the Reese’s family. On the other hand, the Oreo Reese’s Cookie will start as a limited-time release this September, but with a full-time spot in the Oreo portfolio already planned for January 2026, pending successful reception.
Those who can’t wait until September can sign up for early access now on Oreo.com or through Hershey’s official website. Presale opens August 18, and eager fans can order a 24-count box of Reese’s Oreo Cups for $34.99. First shipments are expected to arrive during the week of September 2.
At a time when the snack industry is driven by nostalgia and novelty in equal measure, this partnership strikes the perfect balance. Reese’s and Oreo aren’t just riding the coattails of their past successes—they’re redefining what brand collaborations can look like when flavor, fan service, and fun all collide.
Whether you’re Team Cookie or Team Cup, one thing’s for sure: your snack game is about to get a whole lot sweeter.
