Starbucks is once again pushing the boundaries of beverage innovation in the UK, unveiling its latest menu addition: Protein Cold Foam. Designed to enhance both morning coffees and mid-afternoon matcha moments, this new offering brings a functional twist to one of the brand’s most popular drink customisations.
What Is Starbucks Protein Cold Foam?
Cold Foam has long been a staple at Starbucks, known for its smooth, velvety texture that sits perfectly on top of iced drinks. Now, following its success in the US, Starbucks UK is introducing a protein-packed version.
The new Protein Cold Foam delivers 15g of added protein per serving, without compromising on taste or texture. Available in Vanilla and Caramel flavours, it can be added to a wide range of drinks—from classic iced coffees to matcha lattes and even the popular Iced Oat Shaken Espresso.
This move taps into the growing demand for high-protein, functional beverages, blending indulgence with wellness in a way that feels accessible and customisable.
New Starbucks Protein Drinks in the UK
Alongside the new topping, Starbucks is launching three ready-made protein drinks across UK stores:
Iced Caramel Protein Americano
A lighter option combining Starbucks’ signature espresso with water and ice, finished with sugar-free caramel flavour and topped with Protein Cold Foam.
Iced Caramel Protein Latte
A smoother, creamier take on a classic iced latte, featuring milk, espresso, and caramel flavour, all elevated with the protein-rich foam.
Iced Vanilla Protein Matcha Latte
A standout for matcha lovers, blending green tea with milk and vanilla flavour syrup, topped with vanilla Protein Cold Foam for a refreshing alternative to coffee.
Why Starbucks Is Adding Protein to Its Menu
According to Starbucks EMEA’s beverage development team, this launch is a natural evolution of the brand’s innovation strategy. From Cold Brew to Oat Shaken Espressos, Starbucks has consistently adapted to shifting consumer tastes—and protein is the next big step.
With wellness trends continuing to influence food and drink choices, the introduction of Protein Cold Foam positions Starbucks at the intersection of convenience, flavour, and nutrition.
When and Where to Try It
The Protein Cold Foam and new protein drinks will be available in Starbucks stores across the UK from 9 April. Customers can also customise their existing favourites by adding the topping for an extra protein boost.
Prices start from around £5.50 for drinks, with the Protein Cold Foam available as an add-on for approximately £2 (prices may vary by location).
Whether you’re looking to increase your protein intake or simply want to try the latest coffee trend, Starbucks’ Protein Cold Foam offers a fresh way to upgrade your daily order. It’s another sign that the UK coffee scene is evolving—where taste and function now go hand in hand.
