How to make cold foam

What’s the deal with cold foam? Cold foam is the Starbucks answer to a whipped topping for iced coffee drinks. While we’re generally wary of food trends, we can confirm: this one is delicious. The creamy topping adds just the right frothy charm, without loads of extra calories.

Even better: you can make it at home! Here’s how to make cold foam: a DIY Starbucks recipe so you can enjoy this treat at home.

What is cold foam?

Cold foam is frothed nonfat milk used for topping for cold coffee drinks like iced coffee, cold brew, iced cappuccinos, and nitro coffee. It simulates the frothy topping of the steamed milk in a latte or cappuccino, but at a cold temperature so it doesn’t melt when hitting an iced drink.

The foam has a thick, frothy texture, and gradually settles in as you sip it. Because it’s made with nonfat milk, it adds only a handful of calories to the drink. But the lightly sweet crema topping has a major pay-off in texture! If you’ve had this one at Starbucks, you know: cold foam makes any iced coffee that much better!

The best milk for cold foam

You might think that a full fat milk would make the creamiest, richest cold foam. Some homemade recipes even call for whole milk or heavy cream. But guess what? Skim milk makes the thickest, sturdiest cold foam. That’s because it has a larger percentage of protein when compared to whole milk or 2%.

On the flip side, whole milk makes the best steamed milk for a latte. The lipids in the milk keep the bubbles small, making the best microfoam texture for latte art.

All about Starbucks cold foam

Starbucks launched cold foam in 2014 with the opening of its Reserve Roastery in Seattle. It was first served atop the Americano Con Crema drink, which had a thick dollop of coffee-spiced foam. Today, Starbucks offers cold foam as a topping that you can add to many drinks for an extra 50 cents. Starbucks cold foam drinks include the following:

  • Cold brews
  • Nitro cold brews
  • Iced lattes
  • Iced mochas
  • Iced cappuccinos
  • Iced espresso
  • Iced London Fog tea latte, Iced matcha tea latte, or Iced chai tea latte
  • Violet drink, pink drink, or dragon drink

How to make cold foam: DIY Starbucks recipe

How to make cold foam at home? It’s very simple to make this treat to top all your homemade iced coffees and cold brews: and an incredibly impressive! Here’s what you’ll need to do (or jump to the recipe below):

  • Step 1: Grab a milk frother (or French press). The best way to make Starbucks cold foam at home is using a handheld milk frother. At only $8.00, it’s the best tool for making thick, fluffy foam and is worth the purchase. (Hey, that’s just 16 Starbucks orders of the stuff!). A French press is your next best bet, if you have one. We don’t recommend a whisk for cold foam: it makes foam with large bubbles and a loose texture.
  • Step 2: Froth for 15 to 20 seconds. Add skim milk and simple syrup to a tall cup and froth until very fluffy. It takes only about 15 seconds to whip up into a thick foam. (For the French press instructions, how to How to Froth Milk.)

Variation: add vanilla

Want to step up your cold foam? You can add a hint of vanilla extract to add a delicious nuance to the flavor. At first we wondered whether this would turn the topping a light brown color. But after testing it, it doesn’t make a perceptible difference in whiteness versus the original. Add a very small dash and you’re in business!

Frequently asked questions

What milk is best for cold foam?

Skim or low-fat milk (1% or 2%) froths best due to the higher milk protein content. Non-dairy milks like oat milk can also be used, but experiment to find a brand that froths well.

Why won’t my cold foam froth?

The milk might be too warm. Use cold milk straight from the fridge for optimal frothing. Or, you might not be using enough milk protein: opt for skim or low-fat milk.

Can I flavor my cold foam?

Absolutely! Add a dash of vanilla, vanilla syrup, or a pinch of cinnamon before frothing.

How long does cold foam stay good?

Cold foam is best enjoyed fresh. It will start to lose its texture after about 30 minutes.
