1 cup milk, any kind
1 teaspoon artificial sweetener (or sugar)
1 teaspoon vanilla extract (or chocolate pieces or syrup or fresh fruit or lemon extract)
Choose a bowl or ceramic mug, any container that can be frozen and will hold as much as you make. If its tupperware and you choose to use the lid, remember it will be harder to remove when frozen, otherwise use plastic wrap. (told you this is easy :) ). Mix all ingredients in the bowl. Cover with plastic wrap. Place in the freezer overnight. Next day, let it sit in sun for a few minutes then stir it and you will have ice milk. Until then it just looks like frozen ice lol.
