Krispy Kreme is celebrating December 12 by offering its rare ‘Day of the Dozens’ super-sweet deal.

If you buy a dozen doughnuts today, you can get an additional dozen of Original Glazed doughnuts for $1.

The offer is only valid at participating Krispy Kreme stores, and there is a limit of two redemptions per customer.

Krispy Kreme is known for its dollar dozen deal, which typically happens only twice a year.
