Make Your Own Starbucks Protein Cold Foam Recipe at Home! (A Dietitian’s Protein Coffee Hack!)
I have been adding protein to my coffee for YEARS. Many dietitians and health professionals including Stacy Sims an international exercise physiologist and nutrition scientist with an MSc and PhD and author of FEAR, also enjoys a cup of protein boost in her coffee in the morning.
For me, starting the morning off with added protein in my coffee is a great start to the day and helps me meet my protein goals with lifting and endurance running.
To be honest, this Starbucks copycats cold foam recipe might be the easiest one to DIY! Really, all you need is milk. So, I’ll walk you through how to make two variations of a vanilla cold foam that you’ll want to make again and again.
Two Methods of Making Your Homemade version of Starbucks Vanilla Cold Foam
1st Method: Milk + Vanilla Protein Powder
Whey protein froths in milk extremely well, sometimes too well! It’s the same reason I now add my protein powder last when blending smoothies to prevent them from getting overly frothy.
2nd Method: Milk + Coconut Sugar + Vanilla Extract
This is my preferred topper for hot coffee most mornings. It’s not too sweet and adds just the right amount of vanilla flavor.
Why You Will Love This Recipe
Easy: This might be the easiest recipe I have on this blog!
Customizable: Make this for your favorite morning beverage weather its an iced coffee or a hot americano. Everyone has their own special morning routine! I shared a bit about mine further in this article. What’s yours? Would these protein cold foam hacks elevate your morning?
Protein Goals (check!): From weightlifting to the endurance athlete to someone just trying to get enough protein in your day to help meet your health goals, this recipe meets you where you are at. Plus, I love a good protein or fiber hack!
Equipment Needed
- Hand Frother or Milk Frother
- jar or cup
- measuring cups and spoons (or eye ball it)
Ingredients and Instructions
These recipes couldn’t be simpler. The ingredients include:
Milk: Use a high-protein milk also labeled as ultra-filtered milk. Some brands that carry high-protein milk include Fairlife, Horizon, Darigold, and Lactaid. I use Dairgold, they are a company local to the PNW!
Vanilla Addition: Either 1 tbsp vanilla protein powder or 1 tsp sweetener of choice (coconut sugar, brown sugar, honey, maple syrup, date syrup, agave), ¼ tsp vanilla extract. Alternatively, if you have a vanilla syrup you love a couple tsps of that would also work well.
Step By Step Instructions
First, choose your version:
- Protein-Boosted: Use 4 oz milk + 1 tbsp protein powder.
- Vanilla-Sweetened: Use 4 oz milk + 1 tsp coconut sugar + ¼ tsp vanilla extract.
Add your selected ingredients to a hand frother and froth for 10–15 seconds, or until thick, creamy, and foamy.
Other ways to froth:
- Blend on low speed in a small blender for about 10 seconds.
- Shake vigorously in a mason jar for 30–45 seconds.
Last, spoon or pour the cold foam over coffee of choice (cold brew, iced latte, americano, etc.)
Nutrition (per variation)
As a Registered Dietitian and Certified Nutritionist, adding a protein boosted coffee to your day is the perfect addition to get a head start on meeting your daily goals for protein. The below nutrition information is based on the recipe, see below for more details.

Vanilla-Sweetened: 100 calories | 7 g protein | 10 g carbs | 4 g fat | 0 g fiber
Flavor Variations to Try!
Below are some Protein Cold Foam Flavors Starucks does not carry. Try these flavor combinations for even more variety of fun drinks at home.
- Cinnamon Maple Cold Foam
Add 1 tsp pure maple syrup and ¼ tsp ground cinnamon.
- French Vanilla Cold Foam
Add sweetener of choice with ⅛ tsp vanilla extract and ⅛ tsp almond extract.
- Fall Spice Cold Foam
Mix in ½ tsp pumpkin pie spice (or cinnamon + nutmeg + cloves)
- Pumpkin Spice Cold Foam
Mix in ½ tsp pumpkin pie spice (or cinnamon + nutmeg + cloves) and 1 tbsp canned pumpkin.
- Salted Caramel Cold Foam
Add 1 tsp caramel sauce and a tiny pinch of sea salt before frothing.
- Peppermint Mocha Cold Foam (holiday-ready)
Blend in 1 tsp cocoa powder and ⅛ tsp peppermint extract.
I like to get creative with combinations at home. Sometimes the cold foam doesn’t quite foam up as good as it does for this vanilla cold foam recipe but that is okay with me! I still enjoy it topped over my morning beverage. Don’t be afraid to get wild with your favorite flavors!
Why Make Cold Foam at Home
For me, in addition to its nutritional benefits, I love to make cold foam at home due to its cost savings!
An Iced Vanilla Protein Latte from Starbucks is reported to cost $8.95. That’s nearly $10 for a cup of coffee. Depending on how you make your coffee at home, it can cost less than $1 to make.
Let’s look at the savings
Let’s say the starbucks drink is $8.95 a drink, and making it from home is approx $1.50 per day.
If you buy one coffee every weekday (5 days/week × 52 weeks = 260 days):
- $8.95 × 260 = $2,327 Starbucks
- $1.50 × 260 = $390 Homemade
Savings: $1,937 per year
Don’t get me wrong, I still love an occasional coffee and pastry from my local coffee shop, but I save it for more for those special occasions.
More Than Just Coffee: My Morning Ritual
If you love starting your day with a good cup of coffee, you’ll love this too. I’ve turned my daily brew into a mindful morning ritual that helps me slow down and savor the moment. From my “no recipe” protein coffee routine to the little sweet treats I enjoy it with, it’s a simple reminder that nourishment is about more than just food.

Tips For The Best Protein Cold Foam
- The more cold foam you add, the more the protein and calories increase in your beverage.
- Plant-based protein powders do not work as well as whey protein powders. In general, I just haven’t found a plant-based protein powder that tastes as good as the whey.
If anyone has one they love, send me a message! I want to hear about it!
Best Milk for Cold Foam
A higher protein milk like Dairgold or fairlife adds even more protein to your drink; however, you can use a regular milk if you find the added protein powder to be enough.
You can use 2%, whole milk, or half and half. I’ve even mixed heavy cream in with 2% and whole milk. The higher the fat, the more richness in your cold foam.
Dairy-Free Options: If you are a coffee fanatic and don’t drink milk, you probably already know Barista Oat milk is the go to for foaming for cold foams and lattes. Its natural starches help it foam more like dairy.
Note: Almond milk and other nut milks do not froth quite as nicely.
Storage Suggestions
Cold Foam looses its foam when stored in the refrigerator. However, if you store leftovers in an airtight container, you can just take it out and re froth as needed. Your flavorings are already in there ready to be added to your hot or cold coffee.
