The Official Starbucks Protein Customization Options
Starting in late September 2025, Starbucks introduced permanent protein-based customizations to its menu, making it simple to get a protein boost right from the barista. These options use premium whey protein and can significantly increase the protein content of your order.
Ordering Protein-Boosted Milk
For any hot or iced beverage that uses milk, you can now request protein-boosted milk as a substitute for 2% milk. Starbucks baristas craft this blend fresh daily by mixing unflavored whey protein into creamy 2% milk. This is a fantastic option for lattes, matcha, and iced shaken espressos.
To order:
- Choose your desired drink (e.g., Caffè Latte, Iced Matcha Latte).
- Specify your size.
- Ask for the "protein-boosted milk" as your milk choice. For example: "Can I get a grande Iced Matcha Latte with protein-boosted milk?"
Using this option adds an extra 12–16 grams of protein to a grande beverage, depending on the drink. Be aware that the protein is dairy-based and uses 2% milk, so it is not a suitable option for vegans or those with dairy sensitivities.
Adding Protein Cold Foam
For an extra dose of creamy protein on any cold beverage, opt for the new Protein Cold Foam. This topping adds about 15 grams of protein per grande drink and comes in a variety of flavors, including plain (no added sugar), vanilla, and chocolate.
To order:
- Select a cold drink (e.g., Cold Brew, Iced Coffee, Refreshers).
- Specify your size.
- Ask to add "[flavor] protein cold foam" on top. For instance: "Can I get a grande Cold Brew with vanilla protein cold foam?"
This method is ideal for those who prefer cold drinks and adds a delicious, flavorful layer to your beverage without the chalky texture sometimes associated with protein powder.
The DIY Protein Hack Using a Pre-packaged Shake
Before the official menu customization, a popular customer "hack" involved combining a shot of espresso with a pre-packaged, high-protein shake. This method is still a viable option, especially if you prefer a non-dairy protein source or want more control over the flavor and nutritional profile.
How to Create Your Own Protein-Enhanced Order
- Purchase Your Ingredients: Before approaching the barista, grab a pre-packaged protein shake from the refrigerated display case inside the store. Starbucks often stocks brands like Koia, which can be an excellent choice.
- Order Your Espresso: Ask the barista for a double or triple shot of iced espresso in a Venti cup with extra ice to leave plenty of room for your shake.
- Combine and Enjoy: Pour the protein shake directly into your iced espresso. The shake's sweetness will balance the espresso's bitterness, and you can stir it with a straw to combine.
Benefits of the DIY Hack
- Higher Protein: Certain brands, like Fairlife or Koia, can add 20–30+ grams of protein in a single bottle.
- Flavor Control: Choose from a wide range of flavors available in the refrigerated case.
- Dairy-Free Options: Many packaged shakes are dairy-free or plant-based, offering a solution for those who cannot consume whey protein.

Nutritional Considerations for Your Order
When adding protein to your Starbucks drink, it's essential to consider the overall nutritional profile, including calories and sugar content. While the official protein-boosted milk has no added sugar, many flavored cold foams and bottled shakes do contain sugar.
Tips for Healthier Protein Drinks:
- Opt for Sugar-Free: Ask for sugar-free vanilla syrup in a latte with protein-boosted milk to get a low-sugar protein drink.
- Plain Cold Foam: Choose the plain (no added sugar) protein cold foam for a boost of protein without extra sweetness.
- Check Labels: If using a packaged shake, read the nutrition label to understand the sugar and calorie content.
For specific nutritional information, always use the Starbucks app or website. You can also explore pairing your protein coffee with one of Starbucks' high-protein food options like the Egg White & Roasted Red Pepper Egg Bites or a Protein Box for a more complete meal. More detailed nutritional advice can often be found on platforms like EatingWell.
Conclusion
With Starbucks' recent menu expansion, adding a protein boost to your drink is more convenient than ever before. Whether you opt for the official, barista-prepared protein-boosted milk or cold foam, or you prefer the DIY method of combining an iced espresso with a pre-packaged shake, you have several effective ways to meet your nutritional goals on the go. The choice depends on your drink preference, desired protein amount, and dietary needs. The new options offer a seamless way to incorporate protein, while the classic hack provides flexibility for those with specific dietary restrictions.
