How to Make Cold Foam at Home: 4 Methods, a Simple Vanilla Recipe, and the Tools That Help
By the Steam Wand Studio team ·

Cold foam is the velvety, spoonable layer that floats on top of iced coffee and cold brew. It’s milk (or a milk-and-cream mix) frothed without heat, so it stays cold and holds its shape on top of the drink instead of melting in like steamed milk.
The good news: you don’t need an espresso machine or a café-grade frother to make it. This guide covers four ways to make cold foam at home, a simple vanilla version based on a published recipe, flavor ideas, and troubleshooting tips.
How we put this guide together: the methods and recipe below are drawn from manufacturer instructions and published recipes, which we cite in the Sources section. We have not tested these products or recipes ourselves. Frother details come from manufacturer specifications; prices change, so check the current price.
What is cold foam?
Cold foam is frothed cold milk. Because it isn’t heated, it keeps its chill when you spoon or pour it over an iced drink. Many recipes sweeten or flavor the milk before frothing.
Cold foam vs. whipped cream: whipped cream is usually heavy cream whipped until stiff. Cold foam is typically lighter and pourable, and it’s made with milk or a mix of milk and cream.
The simple vanilla cold foam recipe
This recipe follows the proportions in Starbucks’ published at-home recipe, “Vanilla Sweet Cream Cold Foam.”
Ingredients (1 serving):
- ¼ cup 2% milk
- 1 Tbsp powdered sugar
- ¼ tsp vanilla extract
- Ice and 8 oz of coffee brewed at double strength (for the drink underneath)
Steps (as published):
- Brew coffee at double strength and pour it over ice.
- Combine the milk, powdered sugar and vanilla extract in a separate pourable container.
- Froth the milk mixture using your preferred cold method. Starbucks mentions a handheld milk frother or frothing by hand.
- Top the iced coffee with the cold foam.
Why powdered sugar? It’s finer than granulated sugar, so it mixes into cold milk more easily. If you use a syrup instead, check your frother’s manual first. Nespresso, for example, advises against putting syrup, sugar or chocolate powder directly into the Aeroccino jug because they may damage the coating.

4 ways to make cold foam at home
Method 1: Handheld frother (the most common budget method)
Handheld frothers are battery-powered wands you dip into a container of milk. For cold foam, simply use cold milk and don’t heat it. Subminimal NanoFoamer V2 at Subminimal Subminimal NanoFoamer Lithium at Subminimal
What the manufacturer lists (Subminimal NanoFoamer):
- V2: runs on 2× AA batteries, single speed, up to 3,000 RPM submerged; IPX-4 splash resistant
- Lithium: USB-C rechargeable, dual speed; IPX-4 splash resistant
How to do it:
- Pour your cold milk mixture into a tall glass or jug, leaving room for it to expand.
- Submerge the frother head before turning it on, to limit splashing.
- Froth near the surface to add air, then lower the head to smooth out large bubbles.
- Stop once the foam is thick and pourable.
Method 2: Electric frother with a cold setting (most hands-off)
Some electric frothers have a dedicated cold function, so you press one button and walk away.
Nespresso Aeroccino4 at Nespresso Breville Milk Café at Breville What the manufacturers list:
- Nespresso Aeroccino4: a dedicated cold milk froth setting, maximum 120 mL for froth (hot or cold), and about 80 seconds for cold froth. Nespresso recommends whole or semi-skimmed milk at fridge temperature for best froth.
- Breville Milk Café (BMF600): a Cold Stir setting that froths or stirs without heating and runs for 60 seconds. Breville’s manual says not to exceed the 500 mL CAPP/LATTE MAX line when frothing.
How to do it: add cold milk only up to the froth line, select the cold setting, and pour the foam over your iced drink. Add flavorings to your drink or mix them in afterward, following your frother’s manual.
Method 3: Manual plunger frother or French press
A plunger frother works like a French press. Pumping the mesh plunger whips air into the milk. No electricity is needed.
Bodum Chambord Milk Frother at Bodum
What listings show: Bodum Chambord Milk Frother sizes of 0.08 L, 0.15 L and 0.25 L appear in Bodum listings via search. Bodum’s product URL returned little usable content on re-check (Nov 4, 2026), so confirm size and care details on the listing.
How to do it:
- Add cold milk, leaving plenty of room for it to expand (follow the fill guidance in your frother’s instructions).
- Pump the plunger up and down rapidly until the milk thickens.
- Let it rest a few seconds, then spoon or pour the foam over your drink.
Method 4: Shake it in a jar (no tools needed)
This one is for when you have no frother at all. Starbucks’ recipe notes you can “froth your milk by hand.”
How to do it:
- Add the cold milk mixture to a clean jar with a tight lid, filling it no more than halfway.
- Shake hard until the volume increases and the milk looks foamy.
- Pour or spoon the foam over your drink.
This method typically gives a looser, bubblier foam than a frother. It’s the fastest way to try cold foam before buying anything.
Choosing your milk
Different milks foam differently, so use your frother maker’s guidance as a starting point:
- Nespresso (Aeroccino4): recommends whole or semi-skimmed milk at fridge temperature.
- Starbucks’ published recipe: uses 2% milk.
- Breville (Milk Café): the manual includes a preparation chart of suggested milks.
- Plant-based milks: results vary by brand and formulation. Check your frother’s manual, and consider “barista” versions, which some brands make specifically for frothing.
Tip: start with milk straight from the fridge. Cold foam is, after all, meant to be cold.
Flavor ideas
Swap the vanilla extract or add flavor using ingredients from your pantry or coffee bar:
- Brown sugar cinnamon: a little brown sugar and a pinch of cinnamon.
- Salted caramel: a drizzle of caramel sauce plus a pinch of salt, mixed in before frothing (check your frother’s manual on adding sauces).
- Mocha: cocoa powder mixed with powdered sugar.
- Maple: a spoonful of maple syrup.
- Seasonal: pumpkin spice in fall, peppermint extract in winter.
These are ideas rather than tested recipes. Start small with sweeteners and flavorings and adjust to taste.
Using a cold setting on an electric frother? Follow the manufacturer’s instructions on whether sugar or syrup can go in the jug. For the Aeroccino, Nespresso advises against it.
What to put cold foam on
- Iced coffee: Starbucks’ recipe uses double-strength brewed coffee over ice.
- Cold brew: foam floats on top for a layered look.
- Iced latte: espresso over milk and ice, topped with flavored cold foam.
- Iced chai or matcha: a vanilla or brown sugar foam works on non-coffee drinks too.
Troubleshooting
| Problem | Likely cause | Try this |
|---|---|---|
| Foam is thin and watery | Milk too warm, or not enough air | Use milk straight from the fridge; froth longer near the surface |
| Big bubbles | Too much air too fast | Lower the frother head to smooth the foam; tap the container on the counter |
| Foam sinks into the drink | Foam too loose | Froth longer for a thicker foam; pour slowly over the back of a spoon |
| Milk overflowed | Container too full | Leave room for expansion; stay under your frother’s max line |
| Sugar didn’t dissolve | Granulated sugar in cold milk | Use powdered sugar or a syrup (check your frother’s manual) |
FAQ
Can I make cold foam without a frother? Yes. Shake the cold milk mixture in a sealed jar, or use a French press. Starbucks notes you can froth by hand.
What’s the best milk for cold foam? It depends on your frother. Nespresso recommends whole or semi-skimmed milk at fridge temperature for the Aeroccino4, and Starbucks’ published recipe uses 2% milk.
Can I use heavy cream? Some “sweet cream” cold foam recipes found online mix heavy cream with milk. Heavier mixes are usually thicker, so stay within your frother’s max line.
Can my electric frother make cold foam? Only if it has a cold setting. The Aeroccino4 has a cold milk froth button, and the Breville Milk Café has Cold Stir. Check your model’s manual.
How long does cold foam last? Cold foam is best made right before serving.
