• peppermint extract or 2 fresh mint leaves
• 1-2 drops Green food coloring
• Maraschino Cherries
• Whipped Cream

INGREDIENT NOTES

Vanilla ice cream: Full-fat vanilla ice cream gives you the richest, creamiest result. Don’t use light ice cream or frozen yogurt — the lower fat content makes the shake icy and thin rather than creamy. McDonald’s uses a vanilla soft-serve base, so the closer you can get to a dense, creamy vanilla, the closer your shake will taste to the original.

Milk: Whole milk keeps it thick. The less fat in your milk, the thinner your shake. If you want it extra thick, reduce the milk to ⅓ cup and add more ice cream. If it’s too thick for your blender to process, add a splash more milk and blend again.

Peppermint extract: This is the key ingredient and it’s easy to overdo. Start with ¼ teaspoon — you can always add more, but you can’t take it out. Peppermint extract is intensely concentrated, which is why such a small amount does so much work. If you prefer a milder mint flavor, start with ⅛ teaspoon and taste before adding more.

A note on fresh mint: Two fresh mint leaves will not give you a minty shake — they’ll give you a shake with a whisper of mint that most people won’t even notice. Fresh mint is great as a garnish on top, but peppermint extract is what produces the McDonald’s-level mint flavor this shake is known for.

Green food coloring: 1–2 drops of standard liquid food coloring gives you a pale, soft green. For the bright, vibrant McDonald’s green, use 3–4 drops of liquid food coloring or a very small amount of green gel food coloring. Gel food coloring is more concentrated and gives you a truer color with less product.

How do you make these amazing shamrock shakes?

This is genuinely one of the easiest things you can make — all five ingredients go into a blender and you’re done in under five minutes. But there are a couple of small things that make the difference between a good shake and a great one.

Start with the milk and ice cream in the blender. Putting the liquid in first helps the blender pull the ice cream down without jamming. Add the peppermint extract — ¼ teaspoon to start — and your green food coloring. Put the lid on, blend on high until completely smooth, and then stop and taste it. This is the moment where you decide if you need more mint or more color. A little more extract, another drop of coloring, a quick blend to incorporate — then you’re done.

Pour it into a glass, pile on the whipped cream, and add the cherry on top. Serve immediately. Milkshakes separate and thin out as they sit, so this is a make-it-and-drink-it situation.

TIPS

Taste before you pour. The mint level is completely adjustable before it leaves the blender. Taste, adjust, blend for another five seconds. This is the one step that separates a shake you love from one that’s either too bland or overwhelmingly minty.

Liquid in first. Always add the milk before the ice cream when blending shakes. It gives the blender something to work with immediately and prevents the ice cream from just sitting on the blades and jamming.

Don’t overblend. Once it’s smooth, stop. Overblending warms the shake and makes it thin. Smooth is the goal — creamy and cold, not frothy.

For a thicker shake: Reduce milk to ⅓ cup and increase ice cream slightly. The ratio is everything.

For brighter green: Use gel food coloring instead of liquid. A tiny amount on the tip of a toothpick is enough to produce a vivid color without affecting flavor.

Garnish right before serving. Whipped cream deflates quickly. Add it to the glass right before it goes to the table, not while you’re still blending the next one.
