Cold foam is a creamy, frothy topping originally popularized by coffee giants like Starbucks. Unlike whipped cream, it’s light, airy, and designed to float beautifully on top of iced coffee drinks—adding a velvety texture and a hint of sweetness without overwhelming the drink.
The unique texture is achieved by frothing cold milk or milk alternatives until it’s luxuriously thick but pourable. Cold foam has quickly become a go-to favorite for coffee lovers seeking a café-quality drink at home.
Ingredients
Basic Cold Foam:
-
½ cup nonfat milk (cold)
-
1–2 tsp simple syrup (or to taste)
Optional Add-ins:



-
1–2 tbsp heavy cream (for richer texture)
-
½ tsp vanilla extract
-
Pinch of sea salt (to enhance sweetness)
Substitutions:
-

Step-by-Step Cooking Instructions
-
Chill your ingredients:
Ensure the milk or alternative is cold—this is crucial for a good froth. -
Combine ingredients:
Pour milk and sweetener (and any flavoring) into a frothing device or jar. -
Froth the milk:
-
Using a handheld milk frother: Froth for 20–30 seconds until thick and foamy.
-
Using a blender: Blend on high for 15–30 seconds.
-
No tools? Shake vigorously in a mason jar with a tight lid for about 1 minute.

-
Serve immediately:
Spoon the cold foam over an iced coffee or cold brew for the best texture and taste.
Common Mistakes to Avoid:
-
Using warm milk—it won’t foam well.

Over-frothing—can turn your foam into stiff peaks like whipped cream.
-
Adding too much sweetener—it makes foam too runny.
