Cold foam at home in under two minutes

Cold foam has been a Starbucks staple for years, but in 2026 it's everywhere — and for good reason. It adds a creamy, slightly sweet layer to iced coffee that transforms a basic cold brew into something genuinely special. And making it at home is almost absurdly easy.

You need three things: cold milk, a way to froth it, and about 90 seconds.

What cold foam actually is

Cold foam is frothed cold milk. Unlike steamed milk foam, it's made without heat — which gives it a lighter, almost mousse-like texture that floats on top of cold drinks without dissolving immediately. Skim (skimmed) milk makes the best cold foam, because fat inhibits frothing. Skim milk has more protein and less fat, which is why it whips into a stable, voluminous foam.

Equipment options (from zero to £25)

A jar with a lid: pour cold milk in (no more than halfway), close the lid, and shake vigorously for 30–60 seconds. Works, costs nothing, foam is coarser.

A French press: pour cold milk in, then rapidly pump the plunger 20–30 times. Surprisingly fine foam in about 30 seconds. If you have one already, this is our favourite method.

A handheld electric frother: costs around £6–£12 on Amazon (the IKEA Producera is around £4). Hold just below the milk surface, run for 20–30 seconds. Fast, easy, excellent foam — best everyday option.

The basic cold foam recipe

Pour 60ml of cold skim milk into your frothing vessel. Froth until the volume roughly doubles and it looks thick and creamy. Spoon or pour it over your cold brew, iced coffee, or iced matcha. Drink through it so you get foam with every sip.

Five flavour variations worth making

Vanilla sweet cream cold foam:Add 2 tablespoons of heavy cream plus half a teaspoon of vanilla extract and 1 teaspoon of sugar. Rich, sweet, closest to the Starbucks version.

Brown sugar cinnamon cold foam:Dissolve 1 teaspoon of brown sugar in a tiny splash of hot water, let it cool, add to cold milk with a pinch of cinnamon before frothing. Pairs especially well with cold brew.

Matcha cold foam:Whisk half a teaspoon of ceremonial-grade matcha with a tiny amount of warm water to form a paste, add to cold milk with a little honey. Earthy bitterness plays beautifully against sweet iced lattes.

Lavender cold foam:Add 1–2 teaspoons of lavender simple syrup to cold milk before frothing. Floral, subtly sweet. Works well with vanilla iced coffee or a London Fog.

Chocolate cold foam:Add 1 teaspoon of Dutch-process cocoa powder and 1 teaspoon of simple syrup. Needs a bit more frothing to incorporate. Good on iced mocha.

Dairy-free cold foam

Oat milk is the most popular non-dairy option. Barista-edition oat milk (Oatly Barista, Minor Figures) is formulated to froth better — worth the slight price premium. Soy milk actually froths very well and produces stable, creamy foam. Almond milk produces thin, unstable foam and isn't ideal.

FAQ

Why won't my cold foam thicken?Most likely the milk isn't cold enough. Cold foam requires properly chilled milk. Also check you're using low-fat or skim milk — full-fat doesn't foam well cold.

How long does cold foam last?Best used immediately. It holds its structure for about 15–20 minutes on a cold drink.

Can I make cold foam without a frother?Yes — the jar-and-shake method or a French press both work with no equipment cost.

What's the difference between cold foam and whipped cream?Cold foam is lighter, less sweet, and lower in calories than whipped cream. It's designed to float rather than pile.
