Homemade Copycat Shamrock Shake

The first time I attempted this recipe, my teenage son walked into the kitchen, took one look at the vibrant green mixture swirling in the blender, and asked if I was conducting a science experiment. We both laughed when I poured it into glasses and he realized it was actually a shake. Now it is a March tradition in our house, the way certain cookies belong to December.

Last year I made these for a St. Patricks Day party and watched grown ups faces light up like little kids. Something about that retro green color just makes people happy, even the ones who swear they do not like sweets.

Ingredients

• Vanilla ice cream: Full fat makes all the difference here for that creamy diner style texture, and do not even think about low fat versions
• Whole milk: You can get away with 2 percent but whole milk gives you that luxurious mouthfeel worth every calorie
• Peppermint extract: Start with half a teaspoon because this stuff is potent, you can always add more but you cannot take it back
• Vanilla extract: Just a quarter teaspoon rounds out the mint so it does not taste like toothpaste
• Green food coloring: Four drops gives you a pastel mint green while six drops delivers that bold shamrock look
• Whipped cream: Essential for the full experience, homemade or store bought both work perfectly
• Maraschino cherries: Totally optional but that pop of red against the green makes it feel like a real shake shop creation

Instructions

Gather everything and measure ahead:

There is nothing worse than getting halfway through and realizing you are out of whipped cream or your peppermint extract has mysteriously vanished.

Blend until perfectly smooth:

Start with less milk than you think you need, about three quarters of a cup, because you can always thin it out but you cannot un thin a runny shake.

Taste before you pour:

Dip a spoon in and check the mint level now, before you serve it, because peppermint extract varies wildly between brands.

Pour into the tallest glasses you have:

Something about a shamrock shake in a short glass just feels wrong, and you want room for all those toppings anyway.

Add the finishing touches:

Whipped cream should go on generously, then that cherry right on top like the crown it is, followed by a confetti of green sprinkles.

Save

My neighbor swears she makes these with coconut milk ice cream and says no one can tell the difference. The kids still request mine every March though, and honestly, I look forward to that first sip all winter long.

Getting The Consistency Right

I learned the hard way that softer ice cream blends more easily than rock hard straight from the freezer stuff. Let your ice cream sit on the counter for five minutes before you start, and you will not end up with chunks or have to blend forever.

Making It Your Own

Sometimes I stir in a tablespoon of chocolate syrup for a thin mint version that my husband actually prefers over the classic. The mint chocolate combination is timeless and makes it feel a little more grown up.

Serving Suggestions

These shakes are thick enough to almost eat with a spoon, which is how my kids like them best. Consider pairing with something savory to balance all that sweetness.

• Keep your glasses in the freezer for twenty minutes before serving for that frosted look
• Extra whipped cream never hurt anyone, especially on special occasions
• Have straws ready because some guests will want to sip while others dive in with a spoon

Save

Whether you are celebrating St. Patricks Day or just need a little minty pick me up, this shake delivers joy in a glass. That first cold sip hits different.
