Why You’ll Love This Marshmallow Cold Foam
- Quick: it takes about a minute to mix and froth.
- Light but creamy: milk keeps it pourable while a little cream helps it hold.
- No specialty syrup required: marshmallow creme provides both sweetness and flavor.
- Versatile: use it on cold brew, iced lattes, mochas, or flavored iced coffee.
Ingredients
- 1/3 cup cold 2% milk: gives the foam enough protein to aerate without becoming too rich.
- 2 tablespoons heavy cream: helps the foam feel creamy and sit on top of the drink.
- 2 tablespoons marshmallow creme: adds the signature sweet marshmallow flavor.
- 1/2 teaspoon vanilla extract: rounds out the sweetness.
- Pinch of salt: keeps the foam from tasting one-dimensional.
How to Make Marshmallow Cold Foam
Step 1: Chill the Ingredients
Start with very cold milk and cream. Cold dairy froths more easily and gives the foam a finer, more stable texture.
Step 2: Combine
Add the milk, heavy cream, marshmallow creme, vanilla, and salt to a tall cup, measuring jug, or frothing pitcher. Stir briefly so the marshmallow creme begins to loosen into the liquid.
Step 3: Froth
Froth for 20 to 30 seconds with a handheld frother until the mixture looks airy, glossy, and slightly thickened. Stop while it is still pourable. Over-frothing can push it toward whipped-cream texture.
Step 4: Spoon Over Coffee
Pour or spoon the fresh marshmallow cold foam over iced coffee, cold brew, or an iced latte. Serve immediately while the foam is at its fullest.
How to Froth Without a Handheld Frother
A handheld frother gives the easiest result, but you can also use a small milk frother, French press, or tightly sealed jar. With a French press, pump the plunger quickly for about 20 seconds. With a jar, shake vigorously until foamy, then open carefully.
Best Coffee Pairings
Marshmallow flavor works especially well with strong or slightly bitter coffee because the sweet foam softens the finish without needing to sweeten the entire drink heavily.
- Cold brew
- Iced vanilla latte
- Iced mocha
- Caramel iced coffee
- Banana iced latte
- Toasted marshmallow coffee
Can You Make It With Different Milk?
Yes, but the texture changes. Whole milk makes a richer foam, while skim or 2% milk tends to create more volume. Oat milk can work if you use a barista-style version, though it may be less stable. Almond milk usually produces a lighter, looser foam.
How to Adjust the Texture
- Too thick: add 1 teaspoon cold milk and froth briefly.
- Too thin: froth for another 5 to 10 seconds.
- Not holding on top: make sure the ingredients are very cold and do not skip the heavy cream.
- Too sweet: reduce marshmallow creme slightly and add another tablespoon of milk.
Storage
Marshmallow cold foam is best made right before serving. If needed, refrigerate the unfrothed mixture in a covered container for up to 24 hours, then froth just before using. Already-frothed foam will gradually lose volume as it sits.

Notes
Recipe Method Notes
The most reliable texture comes from cold dairy and a short frothing time. The heavy cream provides enough fat to help the foam linger on top of coffee, while 2% milk keeps the mixture from becoming too dense. Marshmallow creme also thickens the foam slightly, so avoid adding too much at once.
More Marshmallow Cold Foam Questions
How do you make marshmallow cold foam at home?
Combine cold milk, heavy cream, marshmallow creme, vanilla, and a pinch of salt. Stir to loosen the creme, then froth until airy and spoonable. Serve immediately over iced coffee or cold brew.
Can you make marshmallow cold foam with whole marshmallows?
Marshmallow creme is easier to combine with cold milk. Whole marshmallows will not dissolve readily; gently melt them with a little milk, let the mixture cool completely, then froth. The texture can differ from the original recipe.
How do you make toasted marshmallow cold foam?
For toasted marshmallow flavor, stir a small amount of toasted marshmallow coffee syrup into the foam before frothing. Use less marshmallow creme if needed so it does not become overly sweet.
You can also pair this cold foam with our vanilla bean syrup or banana coffee syrup.
Frequently Asked Questions
Can I make marshmallow cold foam without heavy cream?
Yes. Use all 2% milk for a lighter version, but expect the foam to be less rich and to settle more quickly.
Can I use marshmallow syrup instead of marshmallow creme?
Yes, but syrup is thinner than marshmallow creme. Start with 1 tablespoon of syrup and slightly reduce the milk so the finished foam does not become too loose.
Why is my cold foam not getting thick?
The most common causes are ingredients that are too warm, too much liquid, or not enough frothing. Chill everything first and froth in a narrow container so the whisk can pull in more air.
How long does marshmallow cold foam last?
It is best immediately after frothing. The unfrothed mixture can be chilled for up to 24 hours and frothed just before serving.
Can I make it less sweet?
Yes. Reduce the marshmallow creme to 1 tablespoon and increase the milk by 1 tablespoon if needed for the right consistency.
