Cold foam is one of those things that I think everyone makes overly complicated. At its core, it's just lightly aerated dairy that sits atop iced drinks to add texture, flavor, and a little bit of sweetness. It doesn’t need to be perfect to work well.
A simple standard cold foam starts with about ⅛ to ¼ cup of dairy or alt milk and a splash of cream. It can be coconut cream, half-and-half, heavy cream, oat milk, or really whatever you want. You can add a small amount of sweetener, like vanilla or maple syrup.
In my own kitchen, I’m lazy. I often just use half and half on its own, or half and half with a splash of heavy cream if I have it in my fridge. The half-and-half thickens up enough, and I like it because I can just buy it in a large carton and move on with my life, instead of mixing the milk and cream separately. Most of the time, I store cold foam in a glass jar and just shake it when I need it. It takes less effort than frothing every single time and still gives a nice texture to my coffee.
As for flavor, the world is your oyster. Vanilla syrup is the most neutral and works with almost anything. For fruit flavors, freeze-dried fruit powders are best because they don’t thin the foam (but you may need to use a blender to incorporate the powder). Fruit purées can be used in small amounts, but the flavor is dependent on the quality of the fruit, and it will loosen the texture. Using baking extracts or flavored syrups is the best way to extend shelf life, since they don’t introduce as much water as fresh fruits, which can break down the mixture. That makes the foam base more stable if you want to keep it stored and reuse it for a few drinks.
As for storage, cold foam is best kept in a sanitized, sealed jar in the fridge. It will separate a little over time, but a quick shake brings it back together. Even though it can be prepped ahead, try to only make enough for a couple of days at a time.
the most basic cold foam recipe
This is the version I use most often because it is flexible and easy to adjust depending on the drink.
Ingredients
- ¼ cup (60 mL) half and half
- Optional: 1–2 tablespoons heavy cream for a thicker foam
- 1–2 teaspoon syrup, extract, or other flavoring, to taste
- pinch of salt
Instructions
- Add all ingredients to a glass jar or small container. Shake vigorously until the mixture becomes light, slightly thick, and foamy. You can also use a milk frother or blender, but shaking is way easier for everyday use.
- Pour directly over iced drinks and serve immediately.
Notes
Storage: Keep the half-and-half and flavorings in a sanitized glass jar tightly sealed with a lid. Using extracts and syrups instead of fresh fruit helps extend shelf life and keeps the foam more stable. For the best texture, use within 1–2 days and shake before serving.
Yield note: Makes about ⅓ cup finished foam after shaking/frothing, depending on the dairy and flavorings used, which is enough for one generous topping or two light ones.
Texture: Half and half alone creates a lighter foam, while adding a splash of cream gives more structure and a thicker finish. This is the version I use most often because it is flexible and easy to adjust depending on the drink. If you want pipeable, then just whip heavy cream to soft peaks and throw it into a piping bag.
Flavor: You can flavor cold foam with whatever you want: vanilla syrup, maple, honey, baking extracts or fruit. Freeze-dried fruit powders work well because they can add flavor without thinning the texture.
