How to make a vanilla milkshake
Pour the milk into a blender.
You can use any type of milk you want, including low-fat, whole, almond, or soy. Whole milk or 2% milk will give you the most flavorful milkshake, however.
If you only have skim milk, but would like something richer, add a splash of half-and-half or heavy cream. For a thicker milkshake, use only cup (120 milliliters) milk.
