Chocolate milk is a sweetened chocolate-flavored milk. It can be made by mixing chocolate syrup with milk. It can be purchased pre-mixed with milk or made at home by blending milk with cocoa powder and a sweetener, melted chocolate, chocolate syrup, or a pre-made powdered chocolate milk mix. Other ingredients, such as starch, salt, carrageenan, vanilla, or artificial flavoring are sometimes added. To add nutritional value to the product, sometimes some minerals like zinc oxide or iron are added.
