When Starbucks introduced their protein beverages, I set out to recreate the protein cold foam I love at home. This copycat protein cold foam delivers the same creamy, frothy texture and rich flavor you expect from a coffee shop, but with only three main ingredients and about five minutes of prep time. It adds roughly 22 grams of protein per serving, making it a satisfying way to boost your drink. Use it to top iced coffee, cold brew, or espresso-based iced beverages.

Why I Love This Recipe
- It tastes like the Starbucks protein cold foam you know, but you can make it at home in under five minutes.
- You can prepare it with either vanilla or chocolate whey protein powder for two distinct flavor options.
- Each serving supplies about 22 grams of protein, so it’s a great way to add protein to your coffee without sacrificing texture.
Ingredients You Need
- Whey protein powder: This recipe is designed for whey-based protein powder only. Whey produces a smooth, airy foam; plant-based powders tend to make a dense, grainy texture and are not recommended.
- Heavy cream: A small amount of heavy cream helps the mixture whip into a stable, silky foam rather than just a thin, protein-fortified milk.
- 2% milk (such as Fairlife): Adding a little 2% milk prevents the cream from turning into whipped cream and keeps the texture closer to a pourable cold foam. The Fairlife 2% used in testing offers higher protein per cup than traditional milk, but any 2% milk will work.
- Coffee: Serve the foam over cold brew, iced coffee, or an iced espresso drink—cold brew pairs particularly well.

Top Tips for a Copycat Starbucks Protein Cold Foam
Use whey protein only. Whey creates the smooth, light foam you want. Plant-based protein powders were tested and resulted in a thick, gritty texture that does not foam properly.
Choose vanilla or chocolate. Both vanilla and chocolate whey powders produce excellent results — choose the flavor that best complements your coffee.
Serve immediately. This protein cold foam is best when freshly whipped. Over time it will lose volume and turn into a thicker protein milk. If you must store leftovers, keep them chilled and re-froth briefly before using.
Equipment: A handheld milk frother or a hand mixer works best to quickly whip the ingredients to a light, airy foam. A blender can work in a pinch but may over-aerate if left running too long.

Starbucks Protein Cold Foam Recipe
By: Lee Funke
Prep: 5 mins Total: 5 mins Servings: 1

Ingredients
- 2 scoops whey protein powder, vanilla or chocolate (about 4 tablespoons)
- 2 tablespoons heavy cream
- 2 tablespoons 2% milk (Fairlife recommended for extra protein)
- 1 cup cold brew coffee, or coffee drink of your choice
Instructions
- Combine the whey protein powder, heavy cream, and 2% milk in a tall glass or small bowl. Use a wide container so the mixture has room to expand as it foams.
- Froth the mixture with a handheld milk frother or whip with a hand mixer until it becomes thick, creamy, and airy. This usually takes 20–60 seconds depending on your tool.
- Fill a serving glass with ice and pour in cold brew or your preferred chilled coffee. Spoon or pour the protein cold foam over the top.
- Serve immediately and enjoy. Stir gently if you prefer a lighter swirl of foam into your drink.
Tips & Notes
- Stick with whey-based protein powder for best texture; plant-based powders were found to be grainy and dense.
- The foam holds best when served right away; it will gradually lose volume and become thicker if stored. If you do refrigerate leftovers, re-froth briefly before serving.
- If you like a sweeter foam, choose a flavored whey protein or add a small pinch of sweetener to the mixture before frothing.
