How to Make a Shamrock Shake at Home Slideshow

Step 1: Perfect the Vanilla Milkshake

If you can make a vanilla milkshake, you’re more than prepared to make a Shamrock Shake at home. All you need is vanilla ice cream and milk to make the base.

Step 2: Add Peppermint Extract

Peppermint extract goes a long way, remember, so don’t overdo it in your vanilla milkshake. When adding the ingredients to a blender, add the peppermint extract for a creamy mint treat. Our best proportions for a shamrock shake:

2 cups vanilla ice cream

¾ cup of milk

¾ teaspoon peppermint extract

Step 3: Add Food Coloring

As the final touch to your Shamrock Shake, add up to eight drops of green food coloring. (Remember, like peppermint extract, it’s a potent ingredient — so don’t overdo it.) Blend all ingredients on high speed until smooth, and you’re good to go. (Whipped cream and a maraschino cherry not included.)

The Pimped-Out Shamrock Shake

There’s lots of ways to amp up your average Shamrock Shake. The easiest way? Add some chocolate syrup to your glass before pouring in the shake — consider it a homemade version of mint chocolate chip ice cream. Or, as Tasty Kitchen does it, add some Oreos for a crunchy milkshake. The ultimate add-on for a Shamrock Shake? A Girl Scouts Thin Mint. That is, if you’re willing to sacrifice a few for a shake.

The Adult Shamrock Shake

For an Irish treat, you had better add some Irish whiskey to the mix. Jameson or Tullamore is always a good basic Irish whiskey to add to the blender — but keep away from the kids. Not a whiskey fan? Peppermint Schnapps can add a minty kick to your shake, or crème de menthe, as in the Twinkiebelle (adult) milkshake. (If you can still get your hands on a Twinkie, that’s one good way to spice up a Shamrock Shake.) There's more than one way to spike a Shamrock Shake.

The Light Shamrock Shake

Like we said, we can’t — or don’t want to — control just how much whipped cream or ice cream we’re adding to our Shamrock Shakes at home. If you’re looking to avoid the calories, try low-calorie frozen yogurt and skim milk instead, and avoid the toppings at all costs. Want to add some vitamins and protein to the shake?
