Some Dunkin’ stores across the country temporarily ran out of the chain’s signature item.

According to multiple reports, stores in states including Nebraska, New Mexico, and Arizona ran out of doughnuts, posting signs apologizing for a shortage due to a manufacturing error.

In an email to USA TODAY on Tuesday, a spokesperson for Dunkin confirmed a single-supplier issue “temporarily impacted some locations in a handful of states.”

“Less than 1% of Dunkin’ locations are currently still impacted, and we’re actively working to restock those locations,” the spokesperson said in the statement. “We anticipate that inventory will be replenished soon.”

USA TODAY reports that as of Tuesday, locations in Nebraska have replenished their doughnut supply.

The publication also reached out to Krispy Kreme to see if the North-Carolina-based coffee and doughnut chain had any supply issues.

“At Krispy Kreme, we make our doughnuts fresh from scratch every day at shops all across the country,” Dave Skena, the Chief Growth Officer at Krispy Kreme, told USA TODAY in an emailed statement. “We don’t rely on other manufacturers for the awesome doughnuts we serve our guests.”
