Best High-Protein Starbucks Drinks Ranked by Protein Content

🥈 2. Hot Latte with 2% Milk
Protein: ~12–16g

Milk protein (casein + whey) digests slower, keeping you fuller longer.
🥉 3. Cold Brew with Milk
Protein: ~10–14g
Calories: ~80–150
Why it works: Lower calories, strong caffeine, and easy to pair with food.
4. Flat White with Whole Milk
Protein: ~12–15g
Calories: Higher than lattes, but more satiating
5. Cappuccino with Nonfat Milk
Protein: ~9–12g
Calories: Lower due to more foam, less liquid milk
Why Starbucks Drinks Can Be High in Protein
Short answer: milk does the work.
Starbucks doesn't add protein powder to standard drinks. Protein comes from:
- Dairy milk (casein + whey)
- Soy milk (plant protein)
- Custom add-ins (off-menu strategies)
📌 Direct answer: A Starbucks drink becomes "high-protein" mainly through milk choice and serving size not syrups or toppings.
