McDonald's Shamrock Shake
By Todd Wilbur

Recipe Type: Drink
Calories: 550
Cook Time: 10 minutes
Recipe Rating: 4.3 (38 reviews)

It's easy to recreate the flavors of McDonald's annual St. Patrick's Day shake using only four ingredients. The two that make this holiday shake special are the mint extract and green food coloring. Make sure your extract says "mint" and not "peppermint". And if you don't care to have shakes that are green like the real ones, you can forego the food coloring.

Update 3/14/17: For a thicker, mintier shake add only 1 cup of milk. If your blender can't mix it up, add 1/4 cup of milk at a time until it blends. Also, the new Shamrock Shakes have whipped cream and a cherry on top.

2 cups vanilla ice cream
1 1/4 cups low-fat milk
1/4 teaspoon mint extract (not peppermint)
8 drops green food coloring

1. Combine all the ingredients in a blender and blend on high speed until smooth. Stop the blender to stir with a spoon if necessary to help blend the ice cream.

2. Pour into two 12-ounce cups and serve each with a straw.

Serves 2.

Pretty Good

Did this as a group cooking activity with some middle schoolers and they all loved it! I did only put 1 cup of milk in it because it seemed thin when I made it at home before. Other than that, it turned out really well!

This recipe turned out good. Like the previous commenters mentioned, I would use a little less than the recommended amount of milk (if using skim). I also added a tad more mint extract. Using the 1/8 spoon wasn't enough so I added about 1/16 more. Otherwise I would follow the same amount of ice cream recommended...that suffices!! Thanks alot. 🍀 Happy nearly St. Patty's Day!

I am not really a fan of Mc D's shakes as a general rule, but I do enjoy a shamrock shake now and again. To the people complaining about the thickness, McDonald's shakes are fairly runny to begin with, at least when compared to a handmade shake from a diner. To fix this, simply use a higher fat content milk. I used homo. You could also use half-and-half. Be sure to use a GOOD QUALITY ice cream and up the quantity a bit. Lastly, don't over blend it. It is great!
Tastes like the real mcoy.

micky D's shamrock shake

People ard saying both super good and terrible. I myself made this for my wife and I, who LOVES these McDonalds shamrock shakes. First off I used the mint extract (not the peppermint). Same amount of ice cream as called for and 2% milk, it was more runny then expected so I added 2 cups more of the ice cream along with 1\4 tsp. of more mint extract. My peeps that didnt like it, oh well. But I do have to say when adding the cool whip or dream whip with Manchino cherry, Perfect to the taste of a real shamro
Great and Tastey!

It was spectacular! Tasted just like the real thing. Most people are complaining about the thickness. What I did was add 3 cups of ice cream instead of 2 and it was really satisfying.

I just substituted the Rumchata as the milk. Makes a really great adult drink that tastes fantastic as well. You should definitely try it.

We are making smoothies in class and this is the perfect way to make a shamrock shake. My teacher has to buy a lot of ice cream. LOL

Made this for my 13 year old. There was a little bit left, I thought I would try it and WOW, loved it. I used a mint/peppermint extract and its a perfect match for the McDonald's Shamrock Shake. YUMMY

Made a shake for my wife and I to cap off Valentine's Day and we Loved the taste; tasted alot like McDonald's Shamrock Shake.
I'd use frozen milk
Submitted on: 02/13/14
Too much milk--way too runny. I froze milk into ice cubes to make it thicker. Not sweet enough. Added 1/2 tsp. stevia.
Tastes like toothpaste

It has the same taste as mcdonalds, but it is a little difficult getting the right thickness
Submitted on: 12/31/13
I thought the shamrock shake was good -it had a good taste. This really tasted like mcdonalds milkshake. I think if you haven't tried it yet - you should.
It is awesome

This tastes so like the shake at McDonald's there seems like no difference except that it is homemade
Tastes good..
Submitted on: 10/03/13
Tastes very similar. I use a little less milk and would recommend even going to mcds and getting some plain vanilla ice cream from them, to make the shake, it'd be soo good. But overall handy recipe. Love it.
Love it!

Tastes almost exactly like McDonalds Shamrock Shake, and I can get it any season!
This is very good!
Submitted on: 05/27/13
This tastes more like the Shamrock shake than I thought it would. Definitely would try this recipe again! Love it!
Eh, Its Alright
Submitted on: 03/22/13
Definitely does not taste like McDonalds' Shamrock Shake. There's too much milk so it doesn't have a shake-like consistency. It does taste like mint but never would I think this is something that would satisfy my Shamrock Shake craving when it's out of season.

Tastes exactly the same like McDonald's. :)
Taste just like it

Mint extract instead of peppermint is definitely the one to use. Results will depend on the ice cream you use. At the place they say add extract flavored syrups to non fat vanilla ice creams to make their shakes. End result is the same.
