High school and college seniors still have a chance to wear their cap and gown to celebrate their milestone, and with a sweet bonus.

Krispy Kreme announced its 2020 Graduate Dozen promotion, which includes a box of a dozen doughnuts for free. The offer is only available Tuesday, May 19.

To claim a free box, high school or college seniors need to head to a Krispy Kreme store, wear their cap and gown with a 2020 tassel. If students don’t have a cap and gown, they have the option to wear class of 2020 apparel, a 2020 senior letterman jacket or wear a 2020 class ring.

Students can also bring their 2020 student ID showing senior status or their graduation announcement and matching ID. Participating locations may require ID. Seniors must be physically present to redeem the offer.

The doughnut maker is also offering a class of 2020 box available for purchase the week of May 18 through May 24.
