Quick Answer
Cold foam is a popular coffee topping that adds a creamy texture without the heaviness of traditional cream. To make cold foam, you need cold milk (preferably non-fat or skim for best results), a milk frother or blender, and optional flavorings like vanilla or sweeteners. Start by chilling the milk and any flavorings in the refrigerator. Once cold, pour the milk into a frother or blender and blend until it forms a thick, creamy foam. This process typically takes about 30 seconds to a minute. The result is a light and airy foam that can be spooned over iced coffee or cold brew, adding a delightful, creamy layer without additional calories from cream.
Deep Dive
What is Cold Foam?
Cold foam is a modern twist on the traditional milk foam used in hot coffee drinks like lattes and cappuccinos. It was popularized by coffee chains like Starbucks and has become a favorite for iced coffee lovers. Unlike regular foam, cold foam is made from cold milk and is designed to sit on top of iced beverages, providing a creamy texture without melting into the drink.
Ingredients and Equipment Needed
To make cold foam, you will need:
- Cold Milk: Non-fat or skim milk works best as they froth more easily and create a stable foam.
- Milk Frother or Blender: A handheld milk frother or a high-speed blender can be used to aerate the milk.
- Flavorings (Optional): Vanilla syrup, sugar, or other sweeteners can be added for extra taste.
Step-by-Step Guide to Making Cold Foam
1. Chill the Milk: Start by placing your milk in the refrigerator. The colder the milk, the better it will froth.
2. Add Flavorings: If you want flavored cold foam, add a small amount of vanilla syrup or sugar to the milk before frothing.
3. Froth the Milk: Using a milk frother or blender, aerate the milk until it becomes thick and creamy. This should take about 30 seconds to a minute.
4. Serve: Spoon the cold foam over your iced coffee or cold brew. Enjoy the creamy texture without the added calories of cream.
Tips for Perfect Cold Foam
- Use Fresh Milk: Fresh milk froths better and provides a richer taste.
- Experiment with Flavors: Try different syrups or sweeteners to find your perfect combination.

Trivia
Did you know that the concept of cold foam originated in Europe before becoming a hit in the United States? European cafes have long been experimenting with different textures and forms of milk to enhance coffee experiences. The trend caught on in the U.S. thanks to major coffee chains, which began offering cold foam as a way to add a luxurious feel to iced beverages without the added calories of whipped cream. The process of making cold foam is similar to creating meringue, where air is incorporated into a liquid to create a stable foam. This technique not only enhances the visual appeal of your drink but also provides a unique mouthfeel that coffee enthusiasts love. Next time you enjoy a cold brew with cold foam, remember you’re part of a global trend that marries innovation with tradition.
