Iced Protein Matcha
Your best bet for protein is an iced matcha made with boosted milk, which carries 36 g per grande. Lattes made the same way run 27 to 29 g, and a foam topping adds roughly 15 g on top. The ranked table below compares grams and delivery-app prices, then food and bottled options follow.

Every Starbucks protein coffee drink gets its protein from one of two places: protein-boosted milk mixed into the latte, or a protein cold foam poured on top. A grande made with boosted milk carries about 27 to 36 grams of protein, and a cold foam drink carries about 19 to 26 grams. This guide ranks the drinks, explains both add-ons, covers the protein boxes and bottled shakes, and shows how to raise the protein in your own order.

Protein cold foam is a flavored cold foam made with whey protein, poured over a cold drink. Protein-boosted milk is 2% milk mixed with whey protein isolate and sunflower-derived lecithin, used in place of regular milk. Both launched on the Starbucks menu in late September 2025 in the U.S. and Canada.
| Detail | Protein cold foam | Protein-boosted milk |
|---|---|---|
| What it is | Topping for cold drinks | Replacement for dairy milk |
| Protein added | About 15 to 18 g | About 12 to 16 g in a grande |
| Reported price | About $2 extra, varies by store | About $1 extra, varies by store |
| Where it goes | Most cold drinks | Most hot and iced dairy drinks |
The foam comes in banana, vanilla, sugar-free vanilla, chocolate, matcha, salted caramel and brown sugar, plus plain. Starbucks has also listed seasonal pumpkin and pecan versions. Drinks that include foam land at about 19 to 26 g of protein per grande, while the lattes with boosted milk reach 27 to 36 g.
Both add-ons use whey, which comes from milk. That makes them unsuitable for anyone who avoids dairy, and they are not vegan. The boosted milk is not sold on its own, and it cannot be added to drinks that arrive premade with 2% milk. Prices are reported figures from launch coverage and the Starbucks protein page, and they can change, so check the app. For the full list of toppings, see the cold foam flavors page.
The highest-protein drinks at Starbucks are the iced protein matchas, with 36 g per grande, followed by the iced protein lattes at 29 g. The table below ranks the lineup by protein and adds the delivery-app starting price so you can see protein per dollar.

| Iced Sugar-Free Vanilla Protein Matcha | 36 g | $7.95+ |

The best value is the Iced Protein Matcha, which gives about 4.9 g of protein per dollar at the delivery-app price, against about 3.7 g for the hot Vanilla Protein Latte. Adding protein cold foam to any drink gives roughly 15 g on top of what it already has.
The sugar-free iced versions are the best fit. The Iced Sugar-Free Vanilla Protein Latte has 29 g of protein for about 200 calories, and the Iced Sugar-Free Vanilla Protein Matcha has 36 g for about 250 calories, both with no added sugar.
Another route is to add protein foam to a drink that starts low in calories, such as brewed coffee or a plain cold brew. The exact totals depend on the foam flavor, so use the app to check them before you pay. For wider comparisons, the calorie guide and the lower calorie drink ideas pages list lighter options across the menu.
You can raise the protein in almost any order with two add-ons and a few smart swaps. Here is a simple order of steps:
Check the dairy note before you order. Boosted milk and protein foam both contain whey, so they are not for anyone who avoids milk, and Starbucks does not offer a plant-based version of either. The boosted milk replaces dairy milk, so it is not an option for a drink you order with a plant milk.
The add-on prices are reported averages and vary by store. The app will show the exact cost and protein before you pay.
A grande protein latte has 27 g of protein when it is hot and 29 g when it is iced. Protein matcha reaches 28 g hot and 36 g iced. Starbucks says amounts can vary because each drink is made by hand, so check the app for your size.
The Iced Protein Matcha and the Iced Sugar-Free Vanilla Protein Matcha have the most, at 36 g per grande. The iced protein lattes follow at 29 g. Adding protein cold foam to another drink raises its total by about 15 g.
It is a cold foam made with whey protein, available in flavors such as vanilla, chocolate, matcha and salted caramel. It adds about 15 to 18 g of protein to a drink and costs about $2 extra. Drinks with foam land at 19 to 26 g per grande.
No. The milk is 2% milk mixed with whey protein isolate, both of which come from dairy. It is not suitable for a dairy allergy or a vegan diet. Starbucks does not offer a plant-based protein milk, so people avoiding dairy should look at bottled plant-based shakes instead.
Yes. The Iced Sugar-Free Vanilla Protein Latte has 29 g of protein, about 200 calories and 9 g of total sugar with none added. The Iced Sugar-Free Vanilla Protein Matcha has 36 g of protein and 12 g of sugar. Both are on the regular menu.
Cold brew, yes: protein cold foam goes on most cold drinks, and the Vanilla Protein Cream Cold Brew is already on the menu. Frappuccinos are a custom request that depends on the store, so ask the barista before you order.
The foam is about $2 extra and protein-boosted milk is about $1 extra, according to launch coverage and the Starbucks protein page. Both vary by location and can change, so the app is the best place to see the exact total.
There is no protein smoothie or made-to-order shake. You can buy bottled Koia Nutrition Shakes in cacao bean and vanilla bean, which are dairy-free. A bottled Coffee & Protein drink with 22 g of protein is also sold in grocery stores.
The delivery menu lists the Apples & Cheese Trio Protein Box with 22 g of protein, holding Gouda, Colby Jack and aged Cheddar with apples and crackers. Other boxes with eggs or peanut butter appear when they are on the menu, so check your store.
Starbucks announced the protein lattes and cold foam for the U.S. and Canada. Other countries may have different menus or none of these drinks. If you are elsewhere, check the local Starbucks app before you plan an order around them.
