On Saturday, Aug. 23, participating Krispy Kreme stores will be celebrating a special House of Hogwarts day. Any Harry Potter fan who reps their favorite Hogwarts House will get one free original glazed doughnut without having to purchase anything, while supplies last.

Krispy Kreme used a bit of Hogwarts magic to create its new Harry Potter-inspired doughnut collection, giving fans a sweet taste of all four houses, no wand required. The doughnut chain has partnered with Warner Bros.

Krispy Kreme is debuting its new ‘Harry Potter’-themed doughnuts based on Hogwarts Houses. Find out when the limited time only offer will be available and how to get them
