Cold foam transformed iced coffee from a simple drink into a layered experience. That thick, creamy foam sitting on top of your cold brew doesn’t require expensive equipment. Three simple methods recreate cafe-quality cold foam at home.
Quick Answer: Make cold foam by vigorously whisking cold milk for 30-60 seconds until tripled in volume. Use 2% or whole milk for best results. Alternative methods include using a French press (pump 20-30 times) or handheld frother (30-45 seconds). Cold foam lasts 10-15 minutes before deflating.
Method 1: French Press (Best Results)
Pour ½ cup cold milk into a clean French press. Pump the plunger up and down rapidly for 20-30 seconds. The milk will triple in volume and become thick and foamy. Spoon the foam onto iced coffee immediately.
This method produces the most stable foam with the finest texture. The mesh filter creates tiny air bubbles that hold their structure longer than other methods.
Method 2: Handheld Milk Frother (Fastest)
Pour cold milk into a tall glass or jar. Insert a battery-powered milk frother and run it for 30-45 seconds, moving it up and down. The milk will foam and expand.
Handheld frothers cost $10-20 and work in seconds. The foam is slightly less stable than French press foam but still lasts 8-10 minutes.

Method 3: Jar Shake (No Equipment)
Pour ½ cup cold milk into a jar with tight lid. Shake vigorously for 45-60 seconds until foam forms and milk doubles in volume. Pour immediately onto iced coffee.
This method requires zero special equipment but produces larger, less stable bubbles. Use this method when traveling or if you don’t have a frother or French press available.
Best Milk for Cold Foam
- Whole Milk: Creamiest foam, most stable, lasts longest (15+ minutes)
- 2% Milk: Good balance of foam and lightness, lasts 10-12 minutes
- Skim Milk: Light foam, less creamy, deflates in 5-7 minutes
- Oat Milk: Best dairy-free option, creamy texture, lasts 8-10 minutes
- Almond Milk: Thin foam, deflates quickly, not recommended
Flavor Additions
Add flavoring before frothing for even distribution. Try 1 teaspoon vanilla extract, 1 tablespoon chocolate syrup, or ½ teaspoon cinnamon per ½ cup milk. Sweetened cold foam requires 1-2 teaspoons sugar or simple syrup.

Cold foam adds texture and visual appeal to iced coffee without watering it down. Use the French press method for special occasions and the handheld frother for daily use. Both methods take under a minute and cost nothing beyond the milk.
