Keebler hosted a "Butterbeer Cookie Tap Trolley" pop-up one-day event at Grand Central Terminal (Graybar Passage) in New York City on Thursday, March 5, 2026, from 12:00 PM to 8:00 PM.
Keebler first released their limited-edition Harry Potter Butterbeer Fudge Stripes Cookies in early 2025, with reports of them appearing in stores around late January to February.
Following high demand, the Butterbeer-flavored shortbread cookies were brought back in March 2026 for the 25th anniversary of the first film released in 2001.
This 2026 immersive event marked the return of the limited-edition Keebler / Harry Potter Butterbeer Fudge collaboration.
Event Details:
• Location: Grand Central Terminal - Graybar Passage, 89 East 42nd Street, New York, NY.
The event was designed for fans to experience the "magic" of the cookies, which are described as having a butterscotch caramel shortbread flavor.
