Parsippany, N.J. — Keebler has brought back its Limited Edition Harry Potter Butterbeer Fudge Stripes Cookies for a second consecutive year as part of Warner Bros. Discovery’s annual Butterbeer Season campaign. The cookies, inspired by the fictional Butterbeer beverage from the Harry Potter franchise, are now rolling out to retailers nationwide beginning in late February 2026, according to a company announcement.
The limited-time product features a Butterbeer-flavored cookie and fudge coating designed to mimic notes of cream soda and butterscotch. Keebler said the cookies will be available in four designs tied to imagery from the Harry Potter films. The release coincides with the 25th anniversary of the first Harry Potter movie, positioning the return as both a product revival and a franchise milestone.
According to Gabrielle Young, brand manager for Keebler Fudge Stripes, consumer demand drove the decision to reintroduce the collaboration.
Young said the company saw strong engagement during the product’s first run and wanted to expand the experience beyond store shelves by pairing the relaunch with in-person and digital activations.
Pop-up activation and digital engagement
To support the product return, Keebler is hosting a one-day pop-up event at Grand Central Terminal in New York City. The event will take place on March 5 from 12 p.m. to 8 p.m. EST.
The activation will include a themed sampling station called the Hollow Tree Express Treat Trolley. It will also feature a Butterbeer Cookie Tap. The event is free and open to the public.
Alongside the in-person promotion, the brand is expanding its digital campaign. Consumers can scan a QR code on the packaging to access Keebler’s “Open for Magic” digital hub. The hub includes games, recipes, and a Harry Potter trivia contest.
The promotion offers daily and weekly prizes. One grand prize includes a trip to New York City to attend the Broadway production of Harry Potter and the Cursed Child.
The campaign also aligns with Warner Bros. Discovery’s broader Butterbeer Season initiative. The program runs annually from March through May. It includes limited-edition food, beverage, and retail products tied to the franchise.The campaign aligns with Warner Bros.

Industry context: licensed flavors and nostalgia-driven launches
The Butterbeer cookie return reflects a broader trend in the CPG sector. Brands are using entertainment licenses and nostalgia to drive seasonal demand. Food companies are increasingly partnering with film and television franchises. These collaborations create limited-edition flavors that tap into fan communities and boost social media engagement.
Licensed products also give manufacturers a way to test new flavor profiles under a familiar brand umbrella. This approach reduces risk while increasing visibility. With Butterbeer Season now positioned as an annual campaign, Warner Bros. Discovery is treating the flavor as a recurring seasonal asset. It is no longer viewed as a one-off novelty.
Why it matters
Keebler’s Butterbeer cookie relaunch shows how nostalgia, pop culture licensing, and experiential marketing are converging in today’s snack aisle. The brand is pairing a returning product with a physical pop-up and a digital sweepstakes. This approach turns a cookie launch into a multi-channel consumer experience.
For food manufacturers, the strategy underscores the growing importance of limited-time offerings tied to recognizable intellectual property. These campaigns help generate urgency, encourage social sharing, and drive repeat engagement. They also allow brands to experiment without permanently changing core product lines.
