How to make Starbucks Protein Cold Foam
Starbucks Protein Cold Foam is a new, protein-enhanced version of its popular cold foam topping—currently being tested at select U.S. locations.
Ingredients
- Unsweetened or flavored protein powder (whey or plant-based): Approximately 1 scoop (~20-25g). Vanilla-flavored protein powder works well for that sweet, Starbucks-style flavor.
- Low-fat milk or milk alternative (such as almond milk, oat milk, or soy milk): ½ cup (use cold milk for the best results). You can opt for non-dairy milk if you’re vegan or lactose intolerant.
- Honey, maple syrup, or sweetener (optional): ½ teaspoon, if you prefer a hint of sweetness like Starbucks’ cold foam topping.
- Vanilla extract (optional): ½ teaspoon for extra flavor.
- Ice cubes (optional): If you’re blending the foam longer or want extra chill while preparing the recipe.
Instructions
- Prepare your equipment: Grab a frother, handheld blender, or standard blender. For authentic cold foam texture, a milk frother works best!
- Combine the ingredients: Pour the milk (or milk alternative) into your mixing container. Add in 1 scoop of protein powder, and if desired, stir in sweetener and vanilla extract for added flavor.
- Blend or froth: Begin frothing or blending your mixture. If you’re using a handheld frother, tilt the container slightly for thorough aeration. Blend until the foam becomes thick, creamy, and doubles in volume—a soft, cloud-like texture is what you’re aiming for.
- Add to your drink: Once your foam is ready, gently spoon or pour it on top of your chilled coffee, cold brew, or iced latte. Be generous—the stack of foam is part of the indulgent experience!
- Serve and enjoy: Your DIY Starbucks Protein Cold Foam is ready! Sip directly or stir it into your drink for a creamy finish.
Tips for Perfect Cold Foam
- Choose the right protein powder: Go for a protein powder that mixes easily with liquids. If your powder tends to clump, sift it before mixing or pre-dissolve it in a little water before adding it to the milk.
- Use cold milk: Cold milk froths more effectively than room-temperature milk. Chill your milk beforehand for the best results.
- Adjust sweetness and flavor: Starbucks’ Protein Cold Foam is subtly sweet, so if you prefer a sweeter taste, experiment by adding natural sweeteners or flavored syrups.
- Experiment with ratios: Depending on the type of protein powder or milk you’re using, you might need to tweak the ratios to achieve the desired foam texture.
- Make it your own: Customize your cold foam by adding cinnamon, cocoa powder, or a drizzle of caramel for an extra kick of flavor.
- Don’t over-blend: Over-frothing can cause the foam to collapse. Stop blending as soon as you get that airy, creamy texture.
What to serve with
Starbucks Protein Cold Foam is a creamy, protein-packed topping that adds richness to cold brew and iced coffee drinks. While it tastes amazing on its own, pairing it with complementary snacks, beverages, and sides can elevate your coffee experience and make it more indulgent or balanced.
1. Cold Brew Coffee
Classic cold brew, with its smooth and slightly bitter flavor, is perfect under this foam. The protein-rich topping balances the boldness of cold brew with a creamy texture.
2. Iced Espresso Drinks
- Iced lattes: The combination of rich espresso, milk, and cold foam creates a luxurious treat.
- Iced macchiatos: Add protein foam to your caramel or vanilla macchiato for extra texture and satisfaction.
3. Refreshing Tea-Based Drinks
Tea aficionados can try pairing cold foam with unsweetened iced teas (like black tea or matcha lattes). The mild sweetness of Protein Cold Foam complements the tea’s earthy or floral notes.
4. Smoothies or Protein Shakes
Transform a smoothie or protein shake by adding Protein Cold Foam on top. This makes it feel less like a workout drink and more like a café-style indulgence.
Ingredients Substitutes
Starbucks Protein Cold Foam is a creamy, high-protein topping that’s often used on cold brews or iced coffees for a light, frothy texture.
A. Almond Milk Substitute
Almond milk is a common base for the foam because it’s light and froths well. If almond milk isn’t available or preferred, here are some alternatives:
- Oat Milk: A great option for a creamy texture. Oat milk tends to froth well and provides a neutral flavor.
- Coconut Milk: Creates a thicker foam and adds a slightly tropical flavor. It’s ideal if you enjoy a hint of coconut.
- Cashew Milk: Lighter than coconut milk but still rich and creamy, making a good alternative for almond milk.
- Soy Milk: Froths well and is often used as a dairy-free option in coffee-based drinks.
- Dairy Milk (Low-fat or Whole): If you aren’t looking specifically for plant-based milk, cow’s milk works well for cold foam due to its frothing ability, especially skim milk.
B. Protein Powder Substitute
Vanilla protein powder is used to give the foam its signature silkiness and protein boost. If you don’t have vanilla protein powder on hand, try these substitutes:
- Other Protein Powders: You can use flavors like chocolate or plain unflavored protein powder. Brands like whey, pea protein, or collagen protein can work as long as they froth easily.
- Greek Yogurt: Blend a small amount of Greek yogurt with sweetener and milk to achieve the needed creaminess and protein content.
- Silken Tofu: For plant-based protein, silken tofu can be added to the mix and blended until smooth; however, this may add a slightly nutty flavor.
- Powdered Milk (Skim or Whole): Nonfat powdered milk can offer both frothing capabilities and protein content.
- Nut Butter: Almond butter or peanut butter can add creaminess and protein, but be cautious as it may affect the texture and flavor.
C. Sweetener Substitute
Vanilla syrup is the go-to sweetener used in the recipe. If you don’t have vanilla syrup or want to customize the flavor, consider these options:
- Maple Syrup: Adds a natural sweetness and blends well without overpowering.
- Honey: Provides a mellow sweetness that pairs well with cold coffee.
- Agave Syrup: An excellent vegan and neutral option for sweetening.
- Stevia Drops: A sugar-free option; choose vanilla-flavored stevia drops for a similar effect to vanilla syrup.
- Flavored Extracts: If you’d like to try something new, use almond extract, cocoa extract, or even a few drops of peppermint extract to customize the foam’s flavor.
