This Vanilla Sweet Cream Cold Foam recipe is a simple Starbucks copycat that adds a rich, creamy, and sweet vanilla-flavored foam to your cold coffee beverages. Made with heavy cream, whole milk, vanilla extract, and sugar or vanilla syrup, this cold foam can easily be made at home using a French press or handheld frother to create a smooth, velvety topping perfect for iced coffee, cold brew, or espresso drinks.
