Shake Shack launches limited edition Reese's shake. Posted: Sep 1, 2026 / 11:57 AM CDT Updated: Sep 1, 2026 / 09:14 AM CDT DALLAS (KDAF) - Shake Shack launched its new Reese's Peanut Butter Cup Shake today for a limited time at participating locations across the United States. The beverage pairs frozen custard with chocolate and peanut butter candy components inside a crackable shell format. The menu additions follow a 2025 Retailer Survey that ranked Reese's as the nation's top Halloween candy. The item translates the flavor profile of the peanut butter cup into a frozen custard beverage. The Reese's Peanut Butter Cup Shake features vanilla frozen custard hand-spun with Reese's Creamy Peanut Butter and fudge sauce. The beverage is poured inside a crackable dark chocolate shell that customers break through to reach the center. The shake is finished with whipped cream, Reese's Mini Peanut Butter Cups and chopped Reese's Pieces. It is available at most U.S. Shake Shack locations, excluding restaurants located in stadiums, racetracks, roadways and airports.

How Shake Shack is owning the beverage conversation. The fast casual is approaching innovation with its signature spin. Aug 20 2026 Nick Wuest, Shake Shack's senior manager of culinary innovation, remembers the days when a market test meant creating something new for the brand's West Village store and running it for a while. If it sold out, they'd consider scale. But the fast casual has evolved quite a bit since he joined seven-plus years ago. Shake Shack had hiked to about 280 locations across 30 states from its 2004 founding to year-end 2019, including more than 95 international units. Today, there are north of 710 (460 in 35 U.S. states and over 250 outside). Shake Shack upped its systemwide count 15.2 percent in Q2, year-over-year, opening 61 corporate restaurants alongside 40 licensed. From Q2 2025 on, the total lifted from 610 to 703. As you'd imagine, pilots roll at a different pace presently across a system 150 percent bigger. It's a double-edged reality, Wuest says. On one token, the brand must be more deliberate, although the timeline slows. "But the learnings you get," he says, "are worth the wait." Wuest came to Shake Shack from Chef Marc Forgione's restaurants and clocked time with Jacques Torres Chocolate. He began searching for a lifestyle change when he met the person who would become his wife. Suddenly, he didn't want to spend most of his week in a frenzied kitchen. Wuest took a job at Danny Meyer's Union Square Hospitality Group and built its R&D program for events and, eventually, the whole company. After nearly three years, Meyer's rocketing burger fast casual began looking for somebody to do the same. Wuest started by overseeing shakes, beverages, desserts, and advising on menu strategy. Of late, he says, beverages in particular have bumped into the spotlight for Shake Shack, just as they have sector-wide, with QSRs from McDonald's to Taco Bell chasing the margin and demographic gains of tapping in. According to Keurig Dr. Pepper's 2026 State of Beverages Trends report, Gen A/Z guests (13-29 years old) are 40 percent more likely than millennials plus (diners over 30 years old) to consume beverages away from home. Social posts featuring drink "lineups" and beverage rotation rose 30 percent, year-over-year, and Gen A/Z respondents were 75 percent more likely to say their expectations for personalized beverage experiences increased over the past five years. Fifty-six percent noted they were actively looking for limited-edition beverages; 57 percent said they were seeking globally inspired options; and 58 percent were on the lookout for "completely new or unexpected flavors." Wuest credits a host of factors. Rewinding again, he recalls leaving USHG's 27th Street kitchen and seeing only a few options. Perhaps a coffee from La Colombe, or a stop at Dunkin'. Now, he explains, "you could close your eyes, spin in a circle, and probably point to a boba shop." "Just that growth of options," Wuest says. "What bubble tea culture has done to the American palate is really amazing. It's opened us up to so much beyond soda... you can't discredit the influence that Asian beverage culture has had on this culture." No surprise then that mini raspberry popping boba arrived as a limited-time add-on upgrade for Shake Shack last July. The smaller pearls were designed to less likely get stuck in straws or linger at the bottom of cups. Alongside a general growth in beverage parity, Wuest reiterates you can trace much of what's happening today to the explosion of what's unfolding in Asia, where beverage lanes from matcha to fruit teas to brightly colored refreshers are ever-present on social. That rush of sweet options, he says, continue to influence U.S. menus. Yet Shake Shack tries to not merely insert itself into movements without any thought of how it shows up, Wuest continues. Boba, as an example, was an idea the brand explored internally for "years" before diving in. It looked at popping profiles, different sizes of tapioca, and thought about the ops equation of rolling through hundreds of restaurants. "We're just waiting for the right idea, the right moment, where it felt not like we're shoehorning something, but we're really using it thoughtfully and treating it the same way we would any other ingredient we wanted," Wuest says. Shake Shack worked with a supplier on mini popping bobas to develop a product that was all-natural fruit juice and not sweetened with pure candy syrup. It then created pairings so customers could make their own drinks and throw boba into, say, a Sprite, but also be greeted with a composed offering, like a Tropical Mango Shake with Passionfruit Popping Boba that launched this summer alongside Mini Passionfruit Popping Boba Lemonades. Returning to KDP's data, 65 percent of Gen A/Z customers compared to 57 percent of millennials plus, said beverage occasions were tied into food. Fifty-nine and 50 percent, respectively, added they were with "others," suggesting the potential social draw of beverage. And 64 percent of Gen A/Zers (54 percent millennial plus) said they wanted beverages that entertained or inspired them. Gen A/Z was twice as likely to chase beverages to feel nostalgic than older generations, too. Additionally, 81 percent of Gen A/Z, to Wuest's note, said they were drawn to fruity and juice profiles (76 percent for millennials plus); 75 percent said they preferred sweet or indulgent flavors (compared to 68 percent); and 72 percent gravitated toward citrus-forward flavors (versus 68 percent). "We give guests the opportunity to use it as they feel they want it," Wuest says of boba. "But for us, our immediate approach to anything like that would be, what can we build with this instead of just having it on the menu?" Shake Shack generally likes to unveil LTOs as a trio to go bold, such as a Spicy Caramel Shake that landed in January with Gochujang caramel frozen custard, as well as present broader, more mainstream items. It's the same tactic being taken with beverages. If a customer doesn't want to try boba in their lemonade, they can order a more classic strawberry that's still elevated. "We do our best to have a range for our guests," he says. And that brings Wuest to one of Shake Shack's buzziest drops in brand history. The chain's viral Dubai Chocolate Pistachio Shake resurfaced in June. Inspired by the famed Dubai chocolate bar, Shake Shack uses real pistachio frozen custard blended with toasted kataifi shredded phyllo, and tops it with chopped pistachios and more crunchy kataifi. Employees then coat the shake in a crackable dark chocolate shell to mirror the iconic crack of the bar in drink form. The first time Shake Shack ran this stateside - in April 2025 - it spread through 30 locations in NYC, L.A., and Miami. Lines snaked around corners before stores opened. And even being the most expensive shake the brand ever offered, originally at $8.49, units often sold out by noon. In some ways, it harkened back to the afternoons when Wuest and his team tried something new in the West Village, made a batch, and waited to see if inventory evaporated. Shake Shack achieved some of the best new guest acquisition metrics for any product or LTO. It drove incremental traffic and mix. Shake Shack asked operators to cook phyllo dough on flat tops each morning, meaning it couldn't create them all day. Stores prepped 25 or so before eventually finding an ingredient that didn't need the same prep, which opened up innovation. Wuest says he wasn't surprised the LTO was so popular. Normally, Shake Shack's development process takes a year to two years. But with the Dubai Chocolate Pistachio Shake, it went from "hey, we should really do this," he shares, to test to launch in less than six months. "Which is pretty amazing for us at the scale that we did it." The timeline compressed because Shake Shack understood the moment, Wuest adds. But again, it didn't want to just jump to market with whatever it could find. The company brought in pure pistachio paste and aligned to standard on other pieces, like kataifi. Even if you strip the trend, though, Wuest says, it was a viral occasion that introduced customers to plainly great flavors. "Pure pistachio is magic," Wuest says. "It's one of those things we're so lucky to have that flavor come of the world. You put that with a really rich custard that we have and then some nice toasted phyllo dough - it's not surprising that people who went out to try it went back for more." It was the chocolate shell where Shake Shack had a growth moment. The brand is no stranger to sourcing high-level ingredients. Yet this was the first time Wuest could recall pastry chocolatier work happening in restaurants. And speaking to the broader test conversation, Shake Shack had the chance to first trial these flavors globally given its ballooning footprint. The Dubai Chocolate Pistachio Shake had one of its early runs in Dubai across 60 stores and three cities. Wuest says the brand learned a good deal about what to expect in the U.S. and how it could prepare for an item that might sell out. As for what's ahead, Wuest wonders where a couple of beverage headlines might land. Sugar is one. How sustainable is the market's tolerance, which has gone up a lot in recent years? "We went from low sugar, semi good for you, all-natural ingredients, to just putting everything we possibly can in a cup of soda," Wuest says of larger observations. "I'm very curious where does that burst?" He's also inquisitive about the aforementioned nostalgia. That's been a common sight in 2026, whether it's memories showing up on menus or brands catering to generations. It was hard to not discover a Bomb Pop-inspired drink as America's 250th celebration approached. Regardless of what happens, however, Shake Shack, he says, will continue to track culture and respond. "We love to be a part of the conversation," Wuest says.
