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.

A magical new menu is coming to Krispy Kreme, but only for a limited time. Will you discover what’s inside before it disappears?
