Dunkin says its September 30, 2026, Halloween menu includes its first Zero beverage topped with cold foam. Sour Apple Energy combines new Green Apple Zero with sour lemonade and Purple Marshmallow Cold Foam, according to the company’s menu announcement.
The Halloween drinks are available at participating restaurants nationwide for a limited time, while supplies last. The purple foam also appears in espresso, matcha, Refresher and frozen-coffee drinks.
The Zero line debuted March 4. Dunkin described it as a lightly carbonated, zero-sugar energy drink for occasions after morning coffee. Its six starting varieties included combinations of blackberry-tangerine, mango and peach flavors. The launch also carried an afternoon incentive: Rewards members could buy medium Zero drinks for $3 after 1 p.m. from March 4–18 at participating U.S. stores.
By July 8, the range included Watermelon Lime Zero. Marshmallow Cold Foam was already part of the summer menu, appearing on a peanut-butter-flavored Fluffernutter Cloud Latte and in a Fluffernutter Coffee Chiller. Those recipes put the foam alongside espresso and frozen coffee.
The August 19 fall menu carried it into a Tiramisu Cloud Latte and Tiramisu Marshmallow Matcha. That launch also introduced Berry Clementine Refreshers and a Berry Daydream Refresher combining the fruit flavors with oatmilk and Sweet Cold Foam.
A separate October offer will give Boosted Status members 100 bonus points on qualifying orders after 1 p.m., October 1–31, capped at 100 per member per day.
App activation is required. Members can then order ahead in the app, scan their Rewards ID in-store or pay with an enrolled Dunkin card at participating U.S. stores. The offer cannot be combined with another offer, promotion or coupon.
Under the program’s general terms, Boosted Status starts after 12 qualifying visits in a calendar month and lasts through that month and the next three calendar months. The regular earning rate on qualifying purchases is 12 points per dollar for Boosted members, compared with 10 for other members.
A qualifying visit requires a purchase of at least $0.99 after discounts and before tax, at least 60 minutes after the previous qualifying visit. Gift-card purchases, reloads and reward-only transactions do not qualify. Purchases through third-party delivery platforms do not earn points.
