Stir ¼ cup of milk with a dash of honey or sugar. You can adjust this ratio if you’d like your cold foam sweeter. Or leave the sugar out entirely!
Froth using a blender or milk frother.
Using a milk frother, blender, or food processor, froth the milk mixture until it’s thick and creamy. You want the foam to last, so don’t stop blending too early.
Put it on your favorite iced drinks!
Spoon your cold foam onto any iced coffee drink, like cold brew, iced coffee, or an iced latte. Because it’s made up of small bubbles, cold foam doesn’t store well, so we recommend making small batches and using them within a day or two.
