Starbucks Protein Cold Foam Recipe
Starbucks Protein Cold Foam is a creamy, fluffy coffee topping made with milk, protein powder, and sweetener. It’s a healthier, high-protein version of Starbucks’ cold foam that tastes café-quality and can be used on iced coffees, cold brews, or lattes.
Ingredients
- ½ cup nonfat milk or unsweetened almond/oat milk
- 1 scoop vanilla protein powder whey, plant-based, or collagen
- 1–2 tbsp sugar-free vanilla syrup or honey
- ¼ tsp xanthan gum optional, for thick texture
- Ice-cold brewed coffee or cold brew for serving
Optional Add-ins:
- 1 tbsp Greek yogurt for extra creaminess
- Dash of cinnamon or cocoa powder for flavor
Instructions
Blend the Base:
- Add milk and protein powder to a blender or frother.
- Blend for 20–30 seconds until lightly foamy.
Add Sweetener and Stabilizer:
- Add vanilla syrup or honey and xanthan gum (if using).
- Blend again until thick and creamy.
Adjust Consistency:
- If too thick, add 1 tbsp milk; if too thin, add a pinch more protein powder.
Serve Over Coffee:
- Pour your cold brew or iced coffee into a tall glass and spoon the protein foam on top.
Garnish:
- Sprinkle cinnamon, cocoa, or vanilla bean powder for a café-style finish.
Notes
- Always use cold milk straight from the fridge — warm milk won’t foam properly.
- Whey protein isolate gives the best Starbucks-like texture.
