Ingredients for this McDonald’s Shamrock Shake Copycat Recipe

Scroll down to the recipe card at the bottom of the page for the detailed ingredient measurements.

• Vanilla Ice Cream: McDonald's soft serve ice cream is best described as an "old fashioned" vanilla flavor so that's we will use as well.
• Whole Milk: will help add moisture to the ice cream so that it's able to be enjoyed as a drink.
• Green Gel Food Coloring: Try to use the gel if you can so that your shake has its vibrant green color. You could use water-based food coloring, but it won't make the color as bright and vivid.
• Mint Extract: adds that festive minty flavor that makes this green milkshake so unique.
• Toppings: Whipped cream, maraschino cherries, and green sanding sugar.

Flavor Variations

• Chocolate Shamrock Shake: If you're a fan of chocolate and mint together, then this is perfect for you. Use chocolate ice cream instead of vanilla ice cream and sprinkle some chocolate chips over the top of the whipped cream once you're done.
• Shamrock Sundae: Switch the whole milk with heavy cream or light cream and slowly blend the ice cream on low speed just to allow the mint extract to fully mix in. Once it's combined, put it in a bowl and drizzle chocolate syrup all over it.

• Spiked Shamrock: Make boozy Shamrock shakes by adding vanilla vodka for a fun and festive adult version.

Frequently Asked Questions - FAQ

Can I Store Leftover Shamrock Shake?

Preferably not. Milkshakes really lose their consistency when stored in the fridge or freezer and it's hard to get it back. If you can, try to make just enough that you know you will be able to finish it in one sitting.

What Ingredients Can I Substitute?

• For a Light/Skinny Version: Use non-fat ice cream instead of regular. It will significantly reduce the calories of the overall milkshake.
• Instead of Mint Extract: You could use peppermint extract. If you do, use a few drops less because is spicier and more potent than regular mint extract.
• For Vegan Options: Substitute both the ice cream and the milk with their plant-based counterparts or alternatives. They have plenty of options available including almond milk, soy milk, or oat milk.

Can I Use Liquid Food Coloring instead of Gel?

Absolutely. I just personally prefer gel because I feel like it gives a stronger color, but liquid is totally fine.

What is in McDonald's Shamrock Shake Syrup?

McDonald's uses a combination of high fructose corn syrup, drops of green food coloring, and mint flavors to make their Shamrock syrup. They then blend that together with their soft-serve ice cream to create the original mint milkshake.
