Pouring cold foam into a cup of iced coffee.

Recipe Highlights

  • Cold foam is cold, frothed milk, made without heat or steam, for iced drinks. It’s creamy, velvety, and fluffy so it sits on top of the iced beverage before slowly making its way down the cup.
  • It’s sweetened with sugar or simple syrup and can be made flavored by adding flavored simple syrups.
  • At Starbucks, cold foam is made using a special blender to create perfectly smooth, textured foam that’s made up of tiny bubbles. To make it home, all you need a is French press or a handheld milk frother. It only takes a few seconds to get perfect cold foam!

Turn your cold brew instantly into an iced latte by adding cold foam. Try making my Irish Cream Cold Brew, Salted Caramel Cold Brew, and Pumpkin Cream Cold Brew which are all made with cold foam.

Ingredient Notes

Cold foam ingredients.
  • Half & HalfHalf cream and half milk, the cream half is the key to getting perfect cold foam. Milk can be made into cold foam but it’ll be thin and not very fluffy or rich.
  • SweetenerWhite, granulated sugar or simple syrup can be used. Starbucks makes theirs with vanilla syrup and you can use any flavored syrup you like.

Cold Foam Using a Handheld Milk FrotherThis is the second best way to make cold foam since you do get bigger, uneven bubbles but a handheld milk frother is easier to clean than a French press.

  1. Whisk half & half and sweetener using a handheld milk frother.It should take about 20 seconds to get fluffy cold foam.
  2. Pour cold foam on top of an iced beverage.

Expert Tips

  • The goal is to get tiny, uniform bubbles that won’t even look like bubbles since that’s what creates the smooth texture. The French press does a better job of doing this than the handheld milk frother.
  • The French press makes better cold foam but it’s a bit of a chore to clean. The handheld milk frother is much easier to clean than a French press but the cold foam isn’t as smooth since there are bigger bubbles. But they both taste great and adds velvety foam to your iced drink.
  • Don’t overfill the French press. The cold foam will double or triple in volume as air is pumped in, so keep that in mind when you pour the half & half into the French press.
  • Don’t underfill the French press. The strainer needs to be submerged in the half & half so that the air can be pumped into it.
