A cold-brewed or iced coffee drink from Starbucks is my go-to refreshment in hot weather. These drinks are often topped with cold foam to make them even more delicious.
Why not make one at home?
One of the best things is that making cold foam is easy and takes only a couple of minutes. All you need is some milk or cream but you can also add other ingredients to make your cold foam sweet and more flavorful.
In this guide, I will tell you how to make cold foam using simple equipment you can find in most homes.
What is Cold Foam?
Cold foam is a textured and stiff foam familiar from Starbucks drinks like iced mocha, cold-brewed coffees, and even iced teas. Starbucks’ makes their cold foam with non-fat milk. For some drinks they also add sweeteners and flavorings.
Actually, any iced drink in Starbucks can be ordered with cold foam, although there is an extra charge for that.
When you make cold foam at home you don’t necessarily have to use non-fat milk. If you want a creamier foam you can use anything from low-fat milk or half-and-half to heavy cream. However, nonfat milk or low-fat milk is easier to foam and produces plenty of small bubbles for a great texture.

How to Make Cold Foam with a French Press
One popular method of making cold foam with perfect uniform bubbles is to use a French press. But instead of using the power of an electric motor, you have to work your muscles with this method.
- Pour the milk into your French press coffee maker. The amount depends on how big your French press is. You should always put enough so that the filter at the end of the plunger will be properly immersed but not too much as the volume will increase in the process.
- Put the lid and plunger on and pump the plunger up and down.
- You should get a nice cold foam in about 30 to 60 seconds depending on how much milk you used.
- Creates nice cold foam with tiny bubbles

- Shake the container vigorously for about one minute and you should have nice and fluffy foam.
What is the Best Milk to Use for Cold Foam?
Dense and smooth cold foam is best made using nonfat or low-fat milk.
If you want your foam creamier, use milk with higher fat content, half-and-half, or heavy cream.
You can also make your own mixture. Let’s say you have nonfat milk and heavy cream in the ref — you can use half a cup of nonfat milk and add one tablespoon of heavy cream.
What Are Some Flavorings That You Can Add to Cold Foam?
Cold foam can be flavored with anything from chocolate, vanilla, or cinnamon, to more exotic choices like pumpkin spice, or mint extract. Flavored syrups are also a great option since they have the sweetness and flavor combined in one product.
How to Serve Cold Foam?
Pour your cold drink into a glass with ice. Leave enough space for the foam.
Then pour the cold foam on top. You can also use a spoon to add more foam to top it off over the brim of the glass!
