Oreo and Reese’s are teaming up for the sweet collaboration fans have been begging for. Despite being owned by different companies, Mondelēz International (Oreo) and Hershey (Reese’s) are joining forces to launch two new treats that blend their iconic flavors. The move is unusual for rivals — and comes as both companies look for a sales boost in a sluggish snack market.
Mondelēz reported a 3.5% drop in North American sales in Q2, while Hershey is preparing to release its latest earnings report. Both are banking on consumer excitement to drive impulse buys. According to Hershey’s Dan Mohnshine, fans have been pushing the idea for years: “What consumers often start riffing on in social media is ‘What would go great in a Reese’s cup?’ The top brand they consistently mention time and time again is Oreo.”
The first mashup, the Reese’s Oreo Cup, swaps Reese’s traditional chocolate shell for Oreo’s milk chocolate and white crème, then packs in peanut butter mixed with Oreo cookie crumbs. This new candy isn’t just a limited drop — it’s becoming a permanent part of the Reese’s lineup, hitting shelves in September with presales beginning August 18 on Hershey’s website.
Oreo is also bringing back a fan favorite. In 2014, the brand launched an Oreo stuffed with Reese’s peanut butter filling, which was a massive hit. Now, the cookie returns with a twist — Oreo cookie crumbs blended into the filling. The updated version will hit shelves in September for a limited time, before making a permanent comeback in January 2026. Presales kick off the same day as Reese’s, August 18, through Oreo’s website.
The timing comes as confectionery companies face headwinds. Shoppers are pulling back on indulgences, while GLP-1 drugs like Ozempic have cut into snacking demand. Rising cocoa costs have also pushed Hershey to announce “lower double-digit” price hikes.
Still, analysts say collaborations like this one stand out. “The double punch of two popular products will grab consumer attention,” said Neil Saunders of GlobalData. Oreo has already proven the stunt strategy works — it teamed up with Coca-Cola last year on both an Oreo-flavored Coke and a Coke-flavored cookie.
With consumer packaged goods firms under pressure to spark growth, Oreo and Reese’s are betting that this long-awaited duo will deliver — and give snack lovers exactly what they’ve been craving.
