National Proposal Day is celebrated annually on March 20th, and in 2026, Dunkin' is dropping new Wedding Cake MUNCHKINS Donut Hole Treats and, for one day only, giving away a limited-edition "I Dough" ring box at participating Dunkin’ locations nationwide.
The brightly colored Dunkin’ ring box comes with a Wedding Cake MUNCHKIN inside, sweetening memorable moments with a glazed blueberry cake donut hole with wedding cake-flavored sprinkles. On March 20th, guests who purchase a 25- or 50-count order of MUNCHKINS will receive a free "I Dough" ring box and Wedding Cake MUNCHKIN, while supplies last.
Ahead of wedding season, Dunkin' is teaming up with bridal designer Vera Wang to encourage fans to celebrate their own "I Dough" moment in style. Fans who incorporate the Dunkin’ "I Dough" ring box into their proposal moment can enter the contest for a chance to win an exclusive bridal experience at Vera Wang’s flagship salon in New York City or Beverly Hills.
