Cold foam is one of the most satisfying upgrades you can add to any iced coffee drink. Thick, velvety, and slightly sweet, it floats on top of your cold brew or iced latte and slowly incorporates as you drink — creating a layered flavor experience that changes from sip to sip. Here's how to make perfect cold foam at home.
What Is Cold Foam?
Cold foam is frothed cold milk — whipped at cold temperature to create a thick, stable foam that doesn't collapse immediately like warm foam does. Unlike steamed milk foam (which is hot and airy), cold foam is dense, creamy, and holds its shape for several minutes on top of an iced drink.
The Basic Cold Foam Recipe
Ingredients:
- 60ml cold heavy cream or cold whole milk
- 1–2 tsp powdered sugar or simple syrup (optional)
- Pinch of salt (enhances sweetness)
Method:
- Combine cold cream, sweetener, and salt in a small jar or container
- Froth with a handheld electric frother for 20–30 seconds until thick and doubled in volume
- Spoon gently over your iced drink
- Serve immediately
Key tip: Everything must be cold. Warm cream won't foam properly. Keep your cream in the fridge until the moment you froth it.

Oat Milk Cold Foam (Dairy-Free)

- 1 tsp matcha powder
- 1 tsp honey

The Best Drinks for Cold Foam
- Cold brew (black) — the classic pairing. The foam's sweetness contrasts beautifully with cold brew's bitterness.
- Iced Americano — bold espresso base with creamy foam topping
- Iced matcha — vanilla cold foam over iced matcha is exceptional
- Iced tea — cold foam works beautifully over iced black or green tea
Use the Diving Moose Coffee Sumatra Gayo Organic Medium Dark Roast cold brew as your base — its smooth, chocolatey character pairs perfectly with vanilla sweet cream cold foam. Top with the Cooper Street Chocolate Biscotti on the side for a complete summer treat. ☕
