I like to think there is no one in this world who would pass up a thick, creamy milkshake. It's so important to know the how to make the perfect milkshake because messing up the ratio of milk to ice cream will either make your milkshake too thin of too thick, and no one wants that. Milkshakes are the perfect drink year round, but we made this for a fun 4th of July drink. We used different colors and flavors to make ours 4th of July themed but you can leave them out for a classic vanilla smoothie. You can also switch up the flavor of ice cream or the flavor of milk for different milkshakes flavors. The possibilities are endless and so delicious!
