In about a week, Shamrock Shakes will start disappearing from McDonald's again. So if you want them year-round...or you'd rather make them at home instead of drinking a cup of mysterious chemicals...here's how.

Babble.com released a very simple recipe for replicating the Shamrock Shake at home. Just dump these four ingredients into a blender and mix 'em up:

-Three cups of a high-quality vanilla ice cream.

-One-and-three-quarters cups of 1% milk.

-Half a teaspoon of peppermint extract.

-Green food coloring.
