I LOVE my Shammy Shakes from McDonald's! Sadly, in about a week, Shamrock Shakes will start disappearing from McDonald's again. So, if you want them year-round, here's how.
It's very simple. This is a recipe I can actually do. 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.
