Dunkin is officially entering the high protein beverage race with a new add on called Protein Milk, and it is launching with a celebrity boost. Megan Thee Stallion is the face of the campaign and co-creator of a new drink, positioning Dunkin’s protein push as both functional and hype-driven.

Dunkin says Protein Milk is designed to taste creamy without a chalky texture or aftertaste. Guests can add it to drinks that use a milk or non-dairy base, including coffees, lattes, matcha, and Refreshers. The new protein drinks deliver 15 grams of protein for a medium size.

Dunkin’s winter lineup includes Protein Refreshers and Protein Lattes built with Protein Milk, including Megan’s Mango Protein Refresher plus additional protein options like a Strawberry Protein Refresher and multiple Protein Lattes.

Fast food and coffee chains are treating protein like the new default upgrade, similar to how cold foam became a menu staple. Dunkin’s move is also clearly designed to compete with other major chains that have already trained customers to expect protein add-ins and macro-friendly ordering.

Dunkin is not just adding a protein drink. It is adding a new base that can be customized into multiple categories. If Protein Milk lands taste-wise, it becomes a permanent upsell lever, not a seasonal gimmick.
