Homemade Copycat Shamrock Shake

The first time I attempted these at home, I accidentally dumped way too much peppermint extract and ended up with something that tasted like toothpaste. My husband tried to be polite about it, but we both ended up laughing and starting over. Now I measure carefully, and that tiny bit of vanilla makes all the difference between medicinal and magical.

Last summer my daughter begged for these during a heatwave, and I realized they are not just for St. Patricks Day at all. We made them green for a pool party and blue for a 4th of July gathering. Now they are our go to treat whenever the temperature climbs above eighty and we need something cold and sweet.

Ingredients

• Vanilla ice cream: Full fat really does give you that restaurant style creaminess, but do not let it soften too much before blending or you will end up with soup instead of a shake.
• Whole milk: The 2% works fine if that is what you have, but the extra fat in whole milk helps everything come together into that perfectly smooth consistency.
• Peppermint extract: This stuff is potent so start with half a teaspoon and work your way up, because once it is in there you cannot take it back.
• Vanilla extract: It might seem unnecessary since you are using vanilla ice cream, but that little extra layer rounds out the mint and keeps it from tasting one note.
• Green food coloring: Four drops gives you a soft mint green while six drops gets you that bright vivid color from the drive thru.
• Toppings: Whipped cream, maraschino cherries and green sprinkles are optional but honestly they make the whole experience feel like a special occasion.

Instructions

Gather everything and prep your glasses:

Get your blender ready and pull out those tall glasses from the freezer if you have been chilling them, because everything stays colder longer when you serve it in pre chilled glass.

Blend your base:

Dump in the ice cream, milk, both extracts and food coloring then blend on high until it looks like something you would actually want to drink, adding a splash more milk if it is too thick for your straw.

Taste and adjust:

Give it a quick test and add another drop or two of peppermint if you want more mint flavor, or another drop of coloring if it is not quite green enough.

Pour and finish:

Pour into your waiting glasses and go wild with the whipped cream and toppings because that is half the fun, then serve immediately before the melting begins.

My niece asked for these at her birthday party instead of cake, and watching all those kids walking around with bright green mustaches was worth every minute of prep time. Sometimes the simplest treats create the best memories.

Getting That Perfect Texture

I have learned that the ice cream should be firm but not rock hard when you start. If it is too frozen, the blender has to work overtime and you might get warm spots. Too soft and you lose that thick shake consistency that makes these so satisfying to drink through a straw.

Color Without Compromise

The food coloring debate is real in our house, but honestly four drops per shake is minimal. If it bothers you, try the spinach method or just embrace that these are an occasional treat. Life is too short to stress about four drops of green food coloring during a holiday celebration.

Make It Your Way

Once you have the basic ratio down, you can really play around with variations. My sister adds a splash of Irish cream for adult versions, and my dad mixes in chocolate syrup because he cannot resist the combination.

• Try coconut milk and coconut ice cream for a tropical twist
• Blend in a frozen banana for extra thickness and natural sweetness
• Top with crushed mint candies instead of sprinkles for texture

There is something about that bright green color that just makes people happy, even when it is not March. Keep this one in your back pocket for anytime you need to turn a regular afternoon into something worth celebrating.
