The month of March has become synonymous with McDonald’s Shamrock Shakes – minty, green and wonderfully thick, they definitely lure more than a few people into the drive-thru for a quick shamrock shake fix.

How Do You Make a Shamrock Shake?

It’s easy to make! You only need a few ingredients to make a shake at home.

A balance of ice cream and milk keeps the consistency nice and thick, mint extract gives a punch of flavor, and green food coloring gives it that characteristic hue.

With just two simple steps, you’ll learn how to make a milkshake that’s creamy and full of flavor.

Let’s Give It a Whirl!

This copycat McDonald’s Shamrock Shake recipe is ready in just five minutes.

1. Add all your ingredients to a blender and puree until smooth.
2. Pour into glasses and top with whipped cream. Adding sprinkles or a maraschino cherry can make it extra festive.

Tips & Tricks

• Green color: If you want a darker shade of green, you’ll need a few more drops of food coloring. You can also try a gel food color, which is more concentrated. You typically only need 2-3 drops of food gel for every 10 drops of food coloring.
• Mint extract: Plain mint extract uses spearmint, which is much milder than peppermint. Peppermint extract contains significantly more menthol, which gives it a more intense flavor. Either extract will work in a shamrock shake, although plain mint is traditional. Just keep in mind that if you use peppermint extract, you will get a stronger punch of mint flavor. Think peppermint candy canes versus Thin Mints. As a result, you may want to use a little less.
• Adjusting consistency: Play around with the ratio of ice cream to milk to make your shake exactly how thick you like it. Start off with the amounts given in the recipe. Then add more ice cream if you want it to be thicker or more milk to thin it out.

Adjustments & Substitutions

Can I add alcohol to a shamrock shake?

If you want to make your shamrock shake with alcohol, spike away! Crème de menthe would be a great substitute for the mint extract, but you may need to double or triple the amount to get that strong minty flavor. You could also experiment with mint and whipped cream vodkas if you’d like.

Can I make it vegan or dairy-free?

It is possible to make this a vegan and dairy-free shake recipe. However, to keep the flavor and consistency the same, be careful with your substitutions. Oat or soy milk ice cream will have a similar creamy texture. Coconut milk ice cream will work too, but it might be slightly grainy.

For a milk substitute, you’ll want to choose something with a neutral flavor and thicker consistency. Again, oat and soy milks are probably your best options. If you want to use coconut milk, full fat canned will work best. Rice milk is very neutral, but it’s thinner so you’ll need less.

You can leave off the whipped topping or use a non-dairy substitute. Most stores carry spray whipped cream made from almond or coconut milk, or you can find homemade recipes online.

Would this be good with a different flavor of ice cream?

You can definitely experiment with different ice cream flavors. Regular chocolate, mint chocolate chip, or even pistachio might be good ones to try.

• 3 cups (396 g) vanilla ice cream
• 1½ cups (360 ml) whole milk
• ½ teaspoon mint extract
• 6 drops green food coloring
• Whipped cream, for topping

Instructions 

• Place the ice cream, milk, mint extract, and green food coloring in a blender. Puree until smooth.

Notes

• Green color: If you want a darker shade of green, you’ll need a few more drops of food coloring. You can also try a gel food color, which is more concentrated. You typically only need 2-3 drops of food gel for every 10 drops of food coloring.
• Mint extract: Plain mint extract uses spearmint, which is much milder than peppermint. Peppermint extract contains significantly more menthol, which gives it a more intense flavor. Traditional shamrock shakes use plain mint extract, but either will work. Just keep in mind that if you use peppermint extract, you will get a stronger punch of mint flavor.
• Adjusting consistency: Play around with the ratio of ice cream to milk to make your shake exactly how thick you like it. Add more ice cream if it needs to be thicker or more milk to thin it out.
• Adding alcohol: Feel free to make this a spiked milkshake! Crème de menthe would be a great substitute for the mint extract, but you may need to double or triple the amount to get that strong minty flavor. You could also experiment with mint and whipped cream vodkas if you’d like.
• Vegan and dairy-free versions: Oat or soy milk make great substitutes for the milk; if you use coconut milk, be sure to go for the full-fat canned version. If you use rice milk, use less since it is thinner. Oat and soy based ice creams will also work well; if you use coconut milk ice cream, the milkshake may have a grainier texture.
• Different flavors of ice cream: You could totally experiment with different ice cream flavors. Regular chocolate, mint chocolate chip, or even pistachio might be good ones to try.
