One Stop has rolled out Dunkin’ Donuts across 300 company-owned stores.
The rollout kicked off last month, following a trial at 15 sites late last year.
The Tesco-owned retailer said the move was designed to help drive footfall into stores.
The donuts will join recent additions such as Robinsons Fruit Ice Drinks and Costa Coffee, as it aims to bolster its on-the-go offering.
Both the Boston Kreme double pack and the Strawberry Frosted Ring Rainbow Set twin-pack are sold at £2.75. There is also a four-pack available at £4.75.
One Stop said it would be rolling out the range to its franchise stores over next couple of months.
“This will be exciting news for them and another great reason for potential franchisees to join us as we work tirelessly to deliver the very best products and services,” said One Stop head of product Sam Watkins.
“Local convenience stores are the ideal places to pop in and grab purchases like the donuts and customers have been thrilled to see them in store.”
