Black Rock Coffee Bar offers three ways to add protein to a drink, with 13g of Protein added per serving*. All three use Whey Protein concentrate with no additives or sweeteners, hand-crafted by baristas in-shop. Here is how each one works and what to order.
Protein is blended directly into any milk-based drink, including alternative milks. Protein amounts vary by recipe and size - the fan-favorite Caramel Blondie contains 23g of Protein in a large size.
Light, velvety Protein Cold Foam that can be added to any drink on the menu. Available in flavors including (but not limited to): Vanilla, Salted Caramel, and Hazelnut.
Made with 2% milk.
A scoop of Whey Protein added to shakes or smoothies, for guests who want a straightforward addition to a blended drink.
Black Rock Coffee Bar intentionally sources Whey Protein concentrate without additives or artificial sweeteners, so it blends into both hot and cold drinks without altering the flavor profile.
Protein is available at all Black Rock Coffee Bar locations. Explore the protein favorites or order ahead.
