What is Cold Foam?
Cold foam is a frothed, unheated milk topping used for cold coffee drinks. Unlike the hot, steamed milk used for lattes and cappuccinos, cold foam is light and airy, sitting beautifully on top of iced coffee, cold brew, or nitro coffee. It slowly cascades down into the drink, creating a lovely visual effect and a creamy texture with every sip.
The secret to its structure is using low-fat or skim milk, which contains a higher ratio of protein to fat. This protein content allows it to hold air bubbles and create a stable, long-lasting foam without the need for heat.

Making Perfect Cold Foam: A Step-by-Step Guide
Ready to create your own? It only takes a couple of minutes and a few simple ingredients.
What You’ll Need
- Ingredients:
- ½ cup skim or low-fat milk (non-fat works best for a sturdy foam)
- 1 tablespoon maple syrup, simple syrup, or sweetener of your choice (optional)
- ¼ teaspoon vanilla extract (optional)
- Equipment:
- A handheld milk frother, French press, or jar with a tight-fitting lid
Instructions
- Combine Ingredients: In a tall glass or measuring cup, combine the cold milk, sweetener, and vanilla extract (if using). Using a tall container helps prevent splashes while you froth.
- Froth the Milk: Submerge your frother into the milk and turn it on. Froth for about 30 to 60 seconds. Move the frother up and down to incorporate more air until the milk doubles in volume and forms a thick, fluffy foam.
- Pour and Enjoy: Gently pour the cold foam over your favorite iced coffee or cold brew. Watch as it layers beautifully on top. Serve immediately and enjoy the creamy texture.
3 Easy Methods for Frothing
You don’t need a fancy espresso machine to make great cold foam. Here are three reliable methods using common kitchen tools.
Method 1: Use a Handheld Milk Frother
This is the quickest and most effective method. A small, battery-operated milk frother is an inexpensive tool that quickly incorporates air into milk, making it a versatile addition to any kitchen. (Handheld Battery-operated Premium Milk Frother To-Go, n.d.)
- How to do it: Pour your milk mixture into a tall glass, insert the frother just below the surface, and turn it on. As the foam builds, lower the frother to froth the remaining liquid milk. It should be thick and ready in under a minute.
Method 2: Use a French Press
If you already own a French press for making coffee, you have a perfect cold foam maker. The fine mesh plunger is excellent at aerating milk. (Stainless Steel Milk Frother, n.d.)
- How to do it: Pour the milk mixture into your French press, making sure it doesn’t fill more than one-third of the carafe. Place the lid on and rapidly plunge the filter up and down for about 60 seconds. The milk will become thick and frothy.
Method 3: Use a Mason Jar
No special equipment? No problem. A simple jar with a secure lid can get the job done with a little bit of elbow grease.
- How to do it: Pour your milk mixture into a clean jar, filling it no more than halfway. Screw the lid on tightly and shake vigorously for 1 to 2 minutes. The milk will double in size and create a soft, pillowy foam.
Creative Cold Foam Variations
Once you’ve mastered the basic recipe, you can start experimenting with different flavors. The possibilities are endless, but here are a few popular ideas to get you started.
- Salted Caramel Cold Foam: Add 1 tablespoon of caramel sauce and a pinch of sea salt to your milk before frothing. This creates a decadent, sweet-and-salty topping that pairs perfectly with a smooth cold brew.
- Pumpkin Spice Cold Foam: Perfect for the fall season! Mix in 1 tablespoon of pumpkin purée, ½ teaspoon of pumpkin pie spice, and your preferred sweetener. It’s like a pumpkin spice latte, but better.
- Chocolate Cold Foam: Add 1 tablespoon of chocolate syrup or cocoa powder to the milk before frothing. This rich, chocolatey foam is a great way to make a homemade iced mocha.
- Vanilla Sweet Cream Cold Foam: For a richer, creamier texture similar to Starbucks, use a mix of heavy cream and 2% milk. (Starbucks Sweet Cream Cold Foam (3 Ingredients), n.d.) Combine 2 tablespoons of heavy cream, 2 tablespoons of 2% milk, and 1 tablespoon of vanilla syrup, then froth until thickened.
Take Your Coffee to the Next Level
Creating your own cold foam is a simple skill that unlocks a world of delicious coffee possibilities. Not only does it save you money, but it also allows you to customize your drinks exactly as you like them. You can control the sweetness, experiment with new flavors, and impress your friends with your barista-level creations.
So next time you’re craving a fancy coffee shop drink, skip the line and head to your kitchen. With just a few ingredients and a couple of minutes, you can craft the perfect cold foam to elevate your daily coffee into a special treat.
