You may have seen this trend recently at Starbucks, known as ‘Cold Foam’. Cold foam is a replacement for alternative whopped toppings, which would usually be added to the top of iced coffee drinks. Cold foam adds the right amount of frothy delight, without adding a tonne of extra calories.
Here's the perfect recipe for making this sweet treat at home.
What is cold foam?
Cold foam is a frothy, non-fat-based milk that makes for a topping on cold drinks such as iced coffee or cold brew. It simulates the frothy topping of steamed milk in a latte or cappuccino, but at a cold temperature so that it doesn’t melt.
The foam sits on top of the drink with a thick, frothy texture has cold foam on top, which gradually sinks in as you sip it. Since it's created with non-fat milk, it only adds a few calories to the beverage; but, the texture of the mildly sweetened crema topping is significantly improved.
The best milk for cold foam
Many would assume full-fat milk would be better suited to provide the creamiest foam, but it’s quite the opposite. Skimmed milk makes the thickest, sturdiest cold foam. This is because skimmed milk contains a higher percentage of protein compared to whole milk.

How to make cold foam with a French Press
Using the same ingredients, heat the milk and simple syrup together in a pan until it’s boiling. Add the boiling milk to the French Press and pump using quick, short plunges until foamy bubbles form (approx. 30 seconds). Pour into a pitcher and tap it on the counter to break down larger bubbles.
