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.
Why This Trend Is Growing
- Novelty Packaging for Experiences

- Brand-designer Collaborations
- High-profile partnerships between mass-market food brands and luxury designers elevate everyday products into aspirational lifestyle artifacts with cross-industry appeal.
- Limited-time Experiential Promotions
- Time-bound giveaways tied to cultural moments drive amplified foot traffic and social sharing, reshaping promotion strategies around scarcity and memorability.
Industries Being Reshaped
- Food and Beverage
- Consumable brands are positioned to extend margins and customer lifetime value by integrating collectible packaging and themed product variants that tap into celebrations.
- Wedding and Bridal
- The bridal sector can be influenced by novel experiential offerings that blend ceremony-focused merchandising with branded moments outside traditional vendors.
