The Introduction of Protein Cold Foam at Starbucks

Starbucks introduced its protein cold foam nationwide on September 29, 2025, as part of an effort to offer functional, protein-enhanced drinks. This item was developed through an innovation program before its wider release.

Understanding Starbucks Protein Cold Foam

Protein cold foam is distinct from the regular version as it uses a mix of 2% milk and unflavored protein powder, termed "protein-boosted milk". This blend is frothed to create a dense, smooth foam with a richer consistency than standard cold foam.

Preparation of Protein Cold Foam In-Store

  1. A base of 2% milk and unflavored protein powder is combined.
  2. Selected flavoring syrups are incorporated.
  3. The mixture is blended until it forms a thick foam.
  4. The finished protein cold foam is applied to a cold drink.

Available Flavors and Customization

Starbucks offers protein cold foam in a range of permanent and seasonal flavors. Customers can also add the protein-boosted 2% milk to customize other cold beverages.
