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 McDonald's Shamrock Shake recipe 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.

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!
