I like Starbucks cold foam drinks like cold brews, iced lattes, etc. If you like them too, then you will definitely like this Starbucks Protein Cold Foam Recipe.
It’s not only fluffy, creamy, and smooth like the real Starbucks foam, but it also gives you a protein boost without the extra sugar.
It’s the kind of topping that makes your regular iced coffee feel like you bought it from a café. But it costs less, tastes fresher, and is way healthier.
How to Make Starbucks Protein Cold Foam
This Starbucks Protein Cold Foam is a frothy topping you can pour over cold brews, iced lattes, or even matcha drinks. However, it’s made with protein powder instead of just cream and milk.
Ingredients:
- ½ cup nonfat milk: You can also use unsweetened almond milk or oat milk.
- 1 scoop vanilla protein powder: Whey, plant-based, or collagen powder — your choice)
- 1–2 tbsp sugar-free vanilla syrup or honey
- ¼ tsp xanthan gum (optional): This will make your foam thick and stable like Starbucks cold foam
- Ice-cold brewed coffee or cold brew for serving
Optional add-ins:
- 1 tbsp Greek yogurt for a thicker texture
- Dash of cinnamon or cocoa powder for flavor
- A few drops of almond extract or caramel syrup, if you like sweet Starbucks-style twists
You can also use inspiration from the Crockpot Hot Chocolate with Instant Mix and add a touch of whipped topping or chocolate drizzle on top to make it indulgent.
Instructions:
- Add milk and protein powder to a blender, or you can use a frother. And blend it for 20–30 seconds.
- Add your sweetener and optional xanthan gum, then froth again until thick and creamy.
- You can adjust consistency — if it’s too thick, add 1 tbsp milk; if too thin, add a pinch more powder.
- Pour your cold brew or iced coffee into a tall glass, then spoon the protein foam on top.
- Sprinkle cinnamon, cocoa powder, or vanilla bean powder if you want café-style presentation.
That’s it. You’ve got a protein-packed Starbucks-style cold foam at home.
Ingredient Substitutes:
- Milk: Use almond milk or oat milk if you’re dairy-free. Barista versions will froth better.
- Protein Powder: Whey gives the best foam, but plant-based works too. You can use vanilla, unflavored, or even mocha to match your coffee. I had chocolate flavored, so I used that.
- Sweetener: Instead of syrup, you can use stevia, monk fruit, or maple syrup.
- Xanthan Gum: It’s optional and will make your drink thick and stable for layering.
Tips to Make Starbucks Protein Cold Foam Perfect
- You should use cold milk straight from the fridge. Warm milk will never give you that foamy, thick top; it’ll just fall flat and watery.
- You can use whey protein isolate, which will make it creamy and stable, very close to Starbucks’ cold foam texture. If you use plant-based, it will still work, just not that thick.
- If you want café-style thick foam, add a small pinch of xanthan gum or ½ tbsp Greek yogurt; it will make it hold longer and creamier.
- Don’t blend it for a long time. Just a few seconds, until you see it thicken, then stop. Otherwise, it will become thin and start separating.
- Vanilla protein powder will give classic Starbucks sweet foam flavor, and it’ll blend nicely with iced coffee or cold brew.
- Don’t pour syrup all at once. Add a little, taste it, then adjust. It’s easier to make it sweet later, not the other way.
- If you want to make it look fancy, drizzle a little caramel syrup or dark chocolate sauce on top. That’s exactly how Starbucks does those seasonal cold foams.
- Always pour the foam slowly over the drink; don’t mix it immediately. Let it float on top and slowly drip down; that’s the real Starbucks look.
- And make it fresh every time. After 20–30 minutes, the foam will start losing that fluffy texture, so make it right before you drink it.
Variations of Starbucks Protein Cold Foam
Vanilla Sweet Cream Protein Foam:
Add 2 tbsp of vanilla sugar-free syrup and ½ tbsp cream.
This will taste just like Starbucks Vanilla Sweet Cream Cold Foam, but healthier and richer in protein.
Mocha Protein Cold Foam:
Replace vanilla protein powder with chocolate protein powder or add 1 tsp cocoa powder.
You can drizzle some dark chocolate syrup, like I used in Starbucks Dark Chocolate Mocha, to make it extra indulgent.
Caramel Protein Cold Foam:
Mixing 1 tbsp sugar-free caramel syrup and a pinch of sea salt gives a Salted Caramel Cold Foam vibe similar to the Salted Caramel Dark Chocolate variation I shared earlier.
Strawberry Cream Protein Foam:
Use strawberry protein powder or 1 tbsp puree and blend into the milk.
This version tastes amazing on iced matcha or white chocolate mocha drinks. It’s similar in concept to the Nespresso White Chocolate Strawberry Recipe.
Cinnamon Roll Cold Foam:
Add ¼ tsp cinnamon + 1 tbsp brown sugar syrup. It’s perfect for iced cold brews and breakfast-style coffees.
You can pair it with Luxury Chocolate Covered Strawberries or even Crumbl Semi-Sweet Chocolate Chip Cookies for weekend brunch.
What to Serve with Starbucks Protein Cold Foam
With Breakfast:
- Overnight oats or chia pudding, like this High Protein Chia Pudding Without Protein Powder or Yogurt. It’s full of fiber and protein, perfect together in the morning.
- Avocado toast or peanut butter toast, the saltiness and healthy fat go nicely with the smooth foam coffee flavor.
Baked Treats:
- Crumbl Semi-Sweet Chocolate Chip Cookies — that soft, chewy cookie with cold coffee is always a win.
- Muffins, like banana, chocolate chip, or oatmeal style. That little sweetness makes your drink feel more filling.
Light Snacks:
- Almond biscotti or shortbread cookies will give that little crunch with your creamy cold foam coffee.
- Chocolate-covered strawberries or any light fruit dessert. It balances the cold foam’s vanilla flavor really well.
Protein Snacks:
- Protein bars, Greek yogurt bowls, or even small chocolate protein bites if you’re having this post-workout. It’ll make a full high-protein combo without a heavy feeling.
- That’s it. You don’t need another drink next to this. This Starbucks Protein Cold Foam coffee already feels like dessert in a glass, so just something light and simple beside it will be perfect.
Nutrition and Protein Breakdown
Here’s an approximate nutrition based on the base recipe (without syrup):
- Calories: 90–120 kcal per serving
- Protein: 18–25g
- Fat: 1–3g (depends on milk type)
- Carbs: 2–5g
If you use syrups or cream, this will go up slightly — but still far healthier than Starbucks cold foams that usually have 12–18g sugar.
Storage & Make-Ahead Tips
- Don’t store the foam — always make it fresh. It deflates after 30–40 minutes.
- You can, however, store the milk + protein mix in the fridge for 1–2 days and re-blend when needed.
- If you plan to meal-prep, just keep the base liquid in a mason jar and froth before serving.
- For travel drinks, pour your cold brew first, then add foam on top and close the lid lightly (so foam doesn’t collapse).

FAQs
Can I make Starbucks Protein Cold Foam without a frother?
Yes, you can. Just use a small blender, or even a mason jar with a tight lid — shake it hard for 30 to 40 seconds.
It will not be as airy as the frother one, but still creamy and thick enough. If you add a little xanthan gum or Greek yogurt, it will hold better.
What type of protein powder works best for this cold foam?
Whey protein isolate will always give a smoother and creamier texture. Collagen powder works nicely too, because it blends easily and doesn’t leave lumps.
If you’re vegan, plant protein (pea or soy) is fine, just the foam will stay a little thinner, not that café thick.
Can I store the foam or make it ahead of time?
No, don’t try that. Cold foam starts losing its texture after 20 to 30 minutes. It will deflate and become thin.
You can, however, store the milk and protein mixture in the fridge for 1–2 days, and just froth it fresh when you need.
That way, you’ll always get that thick, fluffy, Starbucks-style foam.

I’m a self-taught home cook who turns everyday ingredients into comforting, café-style recipes. I test everything in my own kitchen (sometimes more than once), tweak flavors how I like them, and share only what I actually enjoy.
