Dunkin' is starting 2026 with a major menu upgrade focused on one thing customers keep asking for: more protein, without changing their routine. Instead of limiting protein to a specific drink, Protein Milk can be used in coffees, lattes, matcha drinks, and Refreshers. That means you can turn your regular order into a more filling, protein-packed option with no new habit required.
Besides this Dunkin also introduced 5 new drinks made with Protein Milk, each delivering 15 grams of protein in a medium size.
What Is Dunkin's New Protein Milk?
Dunkin's Protein Milk is a new high-protein milk alternative introduced for 2026 that delivers 15 grams of protein per medium drink. Unlike traditional milk or non-dairy options, Protein Milk is specifically formulated to blend smoothly into Dunkin's coffee, espresso, matcha, and Refresher beverages. The idea is not to replace coffee with a shake, but to boost the protein content of drinks customers already love without changing their order routine.
Protein Milk makes beverages more filling and satisfying by adding protein evenly throughout the drink whether you choose hot coffee, iced lattes, fruity Refreshers, or matcha. By integrating protein directly into the milk base, Dunkin allows customers to enjoy familiar flavors while supporting hunger control, energy levels, and overall nutrition goals.
Protein Milk is available at Dunkin' locations nationwide and can be added to almost any drink that allows a milk base, offering flexibility for breakfast, post-workout, or everyday beverages.
The 5 New Dunkin Protein Drinks
Megan's Mango Protein Refresher
Created in collaboration with Megan Thee Stallion, this drink blends juicy mango flavor with Protein Milk for a bright, tropical sip that's both refreshing and creamy. The mango comes through first, while the Protein Milk smooths the drink out and makes it feel more filling than a standard Refresher.
It's best suited for afternoons, post-workout moments, or when coffee feels too heavy but you still want something energizing.
Strawberry Protein Refresher
A protein-powered take on the fan-favorite Strawberry Dragonfruit Refresher, this version keeps the fruity strawberry flavor intact while adding a smoother, creamier texture.
It's sweet, easy to sip, and more satisfying than a regular Refresher, making it a solid choice for mid-morning or on-the-go fuel.
Caramel Chocolate Iced Protein Latte
This drink combines bold espresso with rich chocolate and sweet caramel flavors, all rounded out by Protein Milk. The added protein gives the latte a thicker, more indulgent texture almost dessert-like without losing its coffee character.
It works especially well as a breakfast replacement or a filling morning coffee when time is tight.
Almond Iced Protein Matcha Latte
Earthy matcha is paired with Protein Milk and a subtle toasted almond flavor in this smooth, whipped iced latte. The almond adds warmth without overpowering the matcha, while the Protein Milk keeps the texture creamy and balanced.
This is a good option for anyone who prefers steady energy over a strong espresso kick.
Iced Protein Latte with Sugar-Free Vanilla
The simplest and lightest option in the lineup, this drink features espresso, Protein Milk, and Sugar-Free Vanilla syrup. The vanilla adds just enough sweetness while keeping sugar low.
It's the most customizable option and easiest to fit into lower sugar routines.
Nutrition Breakdown: How These Protein Drinks Compare
All five drinks provide 15 grams of protein, but calories, sugar, and carbs vary depending on flavor.
