Protein Power Hour: Starbucks says Friday at 8 a.m. is the busiest time for Protein Drinks

What time of the week are most Starbucks customers looking for an extra protein boost? New Starbucks data shows that customers across U.S. company-operated coffeehouses purchase the most Protein Drinks on Fridays at 8 a.m. Since Starbucks introduced Protein to its menu in September 2025, customers can now customize 90 percent of beverages with Protein-boosted Milk or Protein Cold Foam to elevate their favorite Starbucks handcrafted beverages with the flavor they love and the function they need.

Friday Morning Protein Favorites

Leading the list of most-ordered Friday morning handcrafted protein beverages is the Vanilla Protein Latte. A grande protein beverage with Protein-boosted Milk offers 27 to 36* grams of protein with a smooth texture and sweet vanilla flavor. When customizing, the top choice customers make on Friday mornings is Vanilla Protein Cold Foam, which adds 15g* of protein.

Starbucks cold foam is a creamy, frothy topping that enhances cold coffee, tea or Refreshers with added texture and flavor, creating a layered, indulgent drink. Cold foam's popularity continues to rise, with double-digit percentage growth in fiscal 2025 and Q1 fiscal 2026 across U.S. company-operated coffeehouses.
