Auntie Anne’s is making a big deal about the return of its fan-favorite Sour Cream & Onion flavor, now available in Flavor Blast Pretzel Nuggets for the first time, and all-new Honey Mustard Flavor Blast Nuggets with The Flavor Blast Challenge. This one-day-only fan-first experience at Roosevelt Field Mall in Long Island promises to turn “superfans into human pretzel nuggets” by having them step into a Flavor Blast pod with a burst of Sour Cream & Onion pretzel “seasoning,” and grab flying “Pretzel Tokens” (exclusive prizes.) As part of the experience, fans have the chance to pick up coveted prizes, such as Auntie Anne’s Gold Card, which unlocks access to free pretzels for an entire year.

The Flavor Blast Challenge happens on August 23rd, and it’s free and open to the public on a first-come, first-served basis.
