Cold foam is frothed cold milk — light, airy, and non-fat. Whipped cream is heavy cream beaten with air until thick and rich. The key difference: cold foam is made from skim milk (0% fat), which creates a stable foam that floats on cold drinks. Whipped cream is 35–40% butterfat — it’s dense, sweet, and melts quickly into hot or iced drinks.
At Starbucks, the cold foam distinction created the “cold foam” drink category starting in 2018. At home, the choice between the two depends on your drink, your equipment, and what you’re going for: a barista-style float, or a dessert-style topping.

What Is Cold Foam?
Cold foam is frothed skim milk that creates a thick, velvety layer of foam without any heat. It was popularized by Starbucks in 2018 when they introduced Cold Foam Cold Brew — a plain cold brew topped with a thick layer of unsweetened, frothed skim milk.
Why skim milk? Fat prevents foam from forming. Heavy cream becomes whipped cream when agitated because its fat molecules trap air. Skim milk, with virtually no fat, creates a fine, stable foam instead. The proteins in skim milk form a stable network that holds the air bubbles in place.
How cold foam is made:
- Start with cold skim milk (or non-fat milk alternative)
- Froth using a handheld frother, french press plunge method, or blender
- The result: a dense, spoonable foam with fine, uniform bubbles
- Spoon onto cold drinks — it floats on top and doesn’t immediately mix in
The texture distinction: Cold foam feels lighter than whipped cream — almost like a delicate cloud. You can drink through it while still tasting distinct layers (coffee, then foam). Whipped cream is structurally heavier and tends to sink or melt.
What Is Whipped Cream?
Whipped cream is heavy cream (at least 36% butterfat) aerated by mechanical agitation until it doubles in volume and holds soft or firm peaks. The fat in heavy cream stabilizes the air bubbles, giving whipped cream its body and richness.
How whipped cream is made:
- Start with cold heavy cream (chilling the bowl helps)
- Whip using a hand mixer, stand mixer, or whisk
- Add sugar (1–2 tablespoons per cup) and vanilla if desired
- Beat until soft peaks form for topping coffee drinks
At Starbucks: Their whipped cream is made with heavy cream in a pressurized dispenser, pre-sweetened with vanilla syrup. One pump of their whipped cream adds approximately 80 calories.
Why it melts: As whipped cream warms or comes into contact with liquid, the fat structure collapses and the cream liquefies. On an iced drink, this happens within 2–3 minutes. On a hot latte, almost immediately.
How to Make Cold Foam at Home
You don’t need special equipment. The best method for home baristas:
Handheld frother method (easiest):
- Pour 3–4 tablespoons of cold skim milk into a small jar or cup
- Submerge a milk frother and froth for 20–30 seconds, moving the wand up and down
- The foam will roughly triple in volume
- Wait 10 seconds for large bubbles to settle, then spoon onto your drink
French press method:
- Add ⅓ cup cold skim milk to a french press
- Pump the plunger up and down vigorously for 30 seconds
- Let settle for 10 seconds, then pour/spoon the foam
For sweet cream cold foam: Use 2 tablespoons heavy cream + 2 tablespoons skim milk + 1 tablespoon vanilla syrup. The small amount of heavy cream adds richness without preventing foam from forming.
For full instructions, see the complete cold foam recipe guide.
How to Make Whipped Cream at Home
Standard whipped cream for coffee:
- Pour ½ cup cold heavy cream into a chilled bowl
- Add 1 tablespoon powdered sugar and ½ teaspoon vanilla extract
- Whip with a hand mixer on medium-high for 60–90 seconds until soft peaks form
- Spoon or pipe onto drinks immediately
Stabilized whipped cream (holds shape longer): Add ½ teaspoon cream of tartar or 1 tablespoon sour cream to the heavy cream before whipping. This slows melting and helps it hold on iced drinks.
Which Topping for Which Drink?
| Drink | Use Cold Foam | Use Whipped Cream |
|---|---|---|
| Cold brew | ✅ Classic — floats perfectly | Optional (dessert style) |
| Iced latte | ✅ Adds body without diluting | ✅ Starbucks-style |
| Iced cappuccino | ✅ Frothy layer | No |
| Hot latte | No — melts immediately | ✅ Optional topping |
| Hot cappuccino | No | ✅ For a Vienna coffee style |
| Mocha | Either | ✅ Traditional |
| Espresso martini | Cold foam variant | No |
| Frappuccino | No | ✅ Classic topping |
| Cold brew affogato | Cold foam on top | Vanilla ice cream instead |
The rule of thumb: Cold foam for cold coffee drinks where you want a floated milk layer. Whipped cream for hot drinks or anytime you want an unmistakably indulgent topping.
Calorie Comparison
| Topping | Serving | Calories | Fat | Sugar |
|---|---|---|---|---|
| Plain cold foam (skim milk) | 2 oz (60ml) | ~20 kcal | 0g | 3g (natural) |
| Sweet cream cold foam | 2 oz | ~55 kcal | 4g | 5g |
| Vanilla cold foam (Starbucks) | Standard | 35 kcal | 0g | 5g |
| Homemade whipped cream (unsweetened) | 2 tbsp | 50 kcal | 5g | 0g |
| Sweetened whipped cream (1 tbsp sugar) | 2 tbsp | 65 kcal | 5g | 3g |
| Starbucks whipped cream | Standard | 80 kcal | 8g | 2g |
For a lighter option: Cold foam made from skim milk is dramatically lower in calories than any whipped cream variation.
Starbucks Cold Foam vs Whipped Cream
At Starbucks, these are distinct menu offerings:
Cold Foam (free on cold foam drinks): Made from skim milk, unsweetened, salted, or flavored. Standard on Cold Foam Cold Brew, Salted Caramel Cream Cold Brew, and similar cold foam drinks. Each new flavor iteration (vanilla, cinnamon, brown sugar) blends the flavoring directly into the cold skim milk before frothing.
Whipped Cream (free add-on): Heavy cream dispensed from a pressurized canister, pre-sweetened with vanilla syrup. Standard on Frappuccinos. Added as an upsell on lattes, mochas, and Americanos.
The two are never interchangeable on Starbucks drinks — cold foam drinks are designed around the layered, float effect; whipped cream drinks are designed for the melting richness.
Frequently Asked Questions
Is cold foam healthier than whipped cream? Yes, significantly. Plain cold foam made from skim milk contains virtually no fat and around 10–20 calories per serving. Standard sweetened whipped cream has 50–80 calories and 5–8 grams of fat per serving. For a lower-calorie topping, cold foam is the clear winner — though sweet cream cold foam (which uses some heavy cream) narrows the gap considerably.
Can you use whipped cream instead of cold foam? You can, but they perform differently. Whipped cream on a cold brew or iced latte will melt within minutes and mix into the drink, adding fat and sweetness throughout. Cold foam stays separate longer, creating a layered effect where you taste coffee, then foam as you drink through it. Use whipped cream if you want richness; use cold foam if you want the Starbucks-style float.
Why does cold foam use skim milk? The science: fat interferes with foam stability. In whole milk or heavy cream, fat molecules coat the protein network and destabilize the air bubbles. Skim milk (0% fat) has abundant milk proteins but no fat to disrupt them, so the proteins form a stable, fine-bubbled foam when agitated. This is also why foam on a cappuccino made with skim milk is often stiffer and less velvety than foam made with whole milk — it’s more stable but less rich.
Can you make cold foam without a frother? Yes. The french press method works well: add cold skim milk to the press (filling it no more than ⅓ full), then pump the plunger vigorously up and down for 30 seconds. The foam won’t be quite as fine as a handheld frother produces, but it floats effectively on cold drinks. A blender on high speed for 20 seconds also works for a larger batch.
