Cold foam without cream
Skimmed milk and milk powder — protein does the work
Cold foam does not actually need cream. Cream supplies fat and mouthfeel, but what holds the bubbles up is protein. Put the protein back and skimmed milk out-foams cream.
Ingredients
- skimmed or semi-skimmed milk, fridge cold100 ml
- skimmed milk powder3 g
- vanilla extract, optional2 ml
Method
Slurry the powder first
Milk powder into a splash of the cold milk, stirred to a smooth paste. Tipped straight into a full jug it clumps and never disperses.
Add the rest and rest it
Stir in the remaining milk and leave it two minutes so the powder hydrates fully. This is the step that decides the texture.
Whip 40–50 seconds
Roughly twice as long as a cream base. Protein foam builds slower but climbs higher — expect the volume to nearly double.
Check the ribbon
Same target as any cold foam: it should fall off a spoon in a thick ribbon. It will feel airier and less rich than cream, which is the trade.
Pour to order
This one holds about five minutes rather than twenty. Make it when the coffee is already in the glass.
Notes
- Why it works: foam is stabilised by protein, not fat. Skimmed milk has the highest protein-to-fat ratio of any dairy, so it whips into the tallest and driest foam. Cream tastes richer and lasts longer; skimmed climbs higher.
- Greek yoghurt version: 40 g of 0% Greek yoghurt loosened with 60 ml of cold milk, whipped 30 seconds. Thick, tangy, and it holds well on cold brew.
- Dairy-free: barista soy foams best of the plant milks — it has the most protein. Or whip 30 ml of aquafaba to soft peaks and fold 60 ml of oat milk through it.
- Sweetening: vanilla extract, cinnamon or a scrape of cardamom flavours it without sugar. Sugar does stabilise foam, so an unsweetened version needs a few extra seconds of whipping.
