Doughnut and coffee chain Dunkin’ has launched a Halloween costume contest on Instagram, giving fans the chance to win $1,000 and a year’s worth of coffee.

By sharing a Dunkin’-inspired Halloween costume on Instagram with the hashtag #DunkinDressUpContest, fans will be entered into the draw for a chance to win. In addition, one winner each week will receive a $100 Dunkin’ gift card. The contest runs until 1 November.

To provide costume ideas, Dunkin’ has teamed up with influencer Aww Sam, who specialises in DIY costumes and has teamed up with the brand in the past.

To go alongside the competition, Dunkin’ has released a pair of special doughnuts for the Halloween period. There’s ‘Spider’ doughnut, with orange icing and topped with a glazed chocolate Munchkins spider, and an Oreo doughnut, which is filled with vanilla buttercreme and topped with chocolate icing, crumbled Oreo cookie and an orange icing drizzle. In addition to the doughnuts, an Oreo hot chocolate has also arrived.
