For National Proposal Day Today, Dunkin’ is handing out free limited-edition ring boxes at participating locations nationwide, filled with a new Wedding Cake Munchkins flavor and a shot at a Vera Wang
Nobody had Dunkin’ and Vera Wang on their 2026 bingo card, and yet here we are. The coffee chain is marking National Proposal Day on March 20 with a promotion that is equal parts absurd and genuinely fun, and it comes with a real prize attached.
At participating Dunkin’ locations nationwide today, customers who purchase a 25 or 50-count order of Munchkins Donut Hole Treats will receive a complimentary limited-edition ring box stamped with the words ‘I Dough.’ Inside each box is a single Wedding Cake Munchkins donut hole, a glazed blueberry cake donut hole topped with wedding cake-flavored sprinkles. The offer is available while supplies last and is only valid today, March 20.
What the Wedding Cake Munchkins actually are
The new flavor launched the same day as the promotion. The Wedding Cake Munchkins are glazed blueberry cake donut holes finished with wedding cake-flavored sprinkles, built specifically around the National Proposal Day tie-in. They are available at participating locations starting today.
The ‘I Dough’ ring box is designed to be used however customers see fit, whether that is an actual proposal, a bridesmaid ask, or simply a way to make someone laugh on a Friday.
The Vera Wang contest runs through April 3
For customers who take the ring box a step further, Dunkin’ is running a contest in collaboration with designer Vera Wang from March 20 through April 3. One winner will receive a bridal salon experience at one of Wang’s flagship locations in either New York City or Beverly Hills, California.
To enter, customers must film a video featuring the ‘I Dough’ ring box during a proposal moment and post it to Instagram or TikTok. The post must tag both @dunkin and @verawanggang on Instagram or @verawang on TikTok, and include the hashtag #DunkinVeraWangcontest.
The winner will be able to select a wedding gown from one of Wang’s salons. As the finishing touch, Wang will embroider the winner’s regular Dunkin’ order inside the gown as their ‘something brewed,’ a nod to the traditional ‘something borrowed, something blue’ custom.
There is also a merch collection
Dunkin’ is launching a limited-edition merchandise line today in partnership with Vera Wang, available at DunkinRunsOnMerch.com starting at 10 a.m. ET. The collection includes robes, glass tumblers, sweatshirts, sweatpants, pajama sets, and tote bags. Prices range from $22 to $52. The line is positioned around wedding mornings and bachelorette weekends, which is either a natural fit or the strangest branding move of the year, depending on how you look at it.
How to get the ring box today
The process is straightforward. Visit a participating Dunkin’ location Today, order a 25 or 50-count of Munchkins Donut Hole Treats, and receive the complimentary ‘I Dough’ ring box while supplies last. The offer cannot be combined with other promotions and is valid at participating United States locations only.
For a chain that built its identity around keeping things simple and affordable, leaning into a one-day bridal promotion with one of fashion’s most recognizable names is a notable swing. Whether it lands as charming or bizarre probably depends on whether you walk in for a medium coffee and walk out holding a ring box. Either way, the donut hole inside is free.
