What Is Cold Foam and Why Is Everyone Obsessed With It?

Cold foam is a thick airy layer of whipped milk or cream that sits on top of cold coffee drinks without melting into them. Unlike hot steamed milk cold foam holds its texture for several minutes creating a satisfying contrast between the creamy topping and the cold drink beneath. It became mainstream after Starbucks launched their Cold Foam Cold Brew and you can now make a version just as good for a fraction of the cost.

What You Need to Make Cold Foam

You do not need specialist equipment. You need cold milk and a way to froth it cold. The three easiest tools are a handheld milk frother a French press or a lidded jar for shaking. A blender also works excellently. No steam wand required.

The Basic Cold Foam Recipe

Pour 60ml of cold semi-skimmed or whole milk into your chosen frothing vessel. If using a handheld frother hold it just below the surface of the milk and run it for 30 to 45 seconds until thick foam forms. If using a French press pump vigorously 20 to 30 times. For the jar method fill it no more than halfway seal tightly and shake for 30 to 45 seconds. Spoon the foam over your cold coffee and enjoy immediately.

Flavoured Cold Foam Variations

Vanilla Sweet Cream Cold Foam

Add one tablespoon of double cream and one teaspoon of vanilla syrup to your milk before frothing. This makes a richer creamier foam similar to the Starbucks version. Pairs wonderfully with cold brew or iced coffee.

Salted Caramel Cold Foam

Add one teaspoon of caramel sauce and a small pinch of sea salt to your milk before frothing. Drizzle a little extra caramel sauce over the top before serving. Pairs brilliantly with cold brew and iced lattes.

Matcha Cold Foam

Whisk half a teaspoon of ceremonial-grade matcha powder with a tablespoon of warm water to form a smooth paste then mix into your cold milk and froth. The result is a beautiful green earthy foam that works wonderfully on iced vanilla lattes.

Brown Sugar Cold Foam

Mix one teaspoon of dark brown sugar into your milk and stir to dissolve before frothing. Adds a subtle molasses warmth that pairs especially well with cold brew.

Tips for Perfect Cold Foam Every Time

Use cold milk straight from the fridge as warm milk will not foam the same way. Do not overfill your vessel as foam needs room to expand. Froth for long enough as under-frothed milk is watery and flat. Full-fat oat milk is the best dairy-free option and froths surprisingly well.

Frequently Asked Questions

Can you make cold foam without a frother?

Yes. A French press or a sealed jar both work well. You can also use a blender on high for 20 to 30 seconds and the milk will foam up nicely.

What milk makes the best cold foam?

2 percent semi-skimmed milk gives a good balance of foam volume and richness. Whole milk produces a creamier denser foam. For dairy-free full-fat oat milk is the best foamer.

How long does cold foam last?

Cold foam is best used immediately as it starts to break down after five to ten minutes. Make it fresh just before you are ready to serve.

Can I sweeten cold foam?

Yes. Add any syrup sugar or sweetener directly to the milk before frothing. Liquid sweeteners incorporate most smoothly.

Why is my cold foam not thickening?

The most common reasons are milk that is too warm not enough frothing time or too much milk in the vessel. Make sure your milk is fridge-cold and froth for at least 30 to 45 seconds.
