Reasons You’ll Love This Recipe
You will love this recipe because it’s so easy to make. I can make it in under 10 minutes from start to finish. The Ninja machine does all the hard work for you.
It tastes just like those expensive shakes from restaurants but costs much less.
This recipe uses simple ingredients you probably have at home already. You don’t need to go to special stores or buy expensive things. I always have milk and Cool Whip in my fridge.
Ninja Slushie Shamrock Shake Ingredients
- Milk (1.5 cups): Whole milk gives the best creamy taste, but 2% or almond milk also works. Whole milk makes the shake richer and thicker, while plant milk may turn out a bit thinner.
- Condensed Milk (1/4 cup): Sweetened condensed milk adds thickness and sweetness. If not available, mix 2 tablespoons of sugar with 2 tablespoons of heavy cream as a substitute.
- Cool Whip (1 cup): Adds a fluffy texture. Any whipped topping works, or fresh whipped cream can be used.
- Peppermint Extract (1 teaspoon): Provides the mint flavor that makes the shake taste like a shamrock shake. Start with a smaller amount and add more as needed. Too much can taste like toothpaste.
- Green Food Coloring (1/2 teaspoon): Creates the classic green color. Use liquid or gel coloring, starting with a few drops until the desired shade is reached.
- Whipped Cream: Perfect for topping the finished shake. Spray whipped cream or fresh whipped cream both work well.
- Cherry: A red cherry on top makes the shake look festive and adds a sweet finish. Fresh or jarred cherries can be used.
Recommended Equipment
- Ninja Kitchen Slushie machine – The main tool that makes your shake smooth and creamy
- Large pitcher for mixing – To combine all ingredients before putting them in the machine
- Measuring cups and spoons – To get the right amount of each ingredient
- Tall glasses for serving – Perfect size glasses to hold your finished shake
- Long spoons for stirring – To mix ingredients well and for drinking the shake
- Ice cream scoop (helpful but not needed) – Makes it easier to scoop out Cool Whip
How To Make Ninja Slushie Shamrock Shake
Step 1 | Add the Cold Milk
Pour 1.5 cups of cold milk into your pitcher. Cold milk works better than room-temperature milk.
Next, add 1/4 cup of condensed milk to the pitcher. Pour it slowly so it blends well with the milk.

Step 2 | Add the Cool Whip
Now add 1 cup of Cool Whip to your pitcher. Scoop it out gently and add it to the milk mixture. Don’t worry if it looks lumpy at first – we will mix it all together.

Step 3 | Add Peppermint Extract
Measure 1 teaspoon of peppermint extract and pour it into the pitcher. This is what makes it taste like a real shamrock shake. The smell will be amazing!

Step 4 | Add Food Coloring
Add the green food coloring next. Start with 3–4 drops and see what color you get. You want a nice light green color like spring grass. Add more drops until you get the perfect green color you like.

Step 5 | Mix the Ingredients
Take a big spoon and mix everything together really well. Stir for about 2 minutes until the color looks the same all over and you don’t see any white streaks. The mixture should be smooth and pretty green.

Step 6 | Pour into Ninja Slushie Machine
Pour your green mixture into the Ninja Kitchen Slushie machine. Make sure you pour slowly so nothing spills. Fill it up to the right line – don’t put too much or it might overflow.

Step 7 | Blend the Shake
Look for the “Milkshake” button on your Ninja machine and press it. The machine will start working and mixing everything up. You will hear it working – this is normal and good!

tep 8 | Wait for Slushy Texture
Wait for the machine to finish. It usually takes about 2–3 minutes to get the perfect slushy texture. Don’t open it while it’s working. Let the machine do its job.

Step 9 | Pour the Shake
When the machine stops, your Ninja Slushie Shamrock Shake is ready! Pour your finished shake into tall glasses. Fill them about 3/4 full so you have room for toppings.

Step 10 | Add Toppings and Serve
Add whipped cream on top of each glass. You can make it as high as you want. Put a red cherry right on top of the whipped cream. Serve and enjoy.

Tips for Perfect Shamrock Shake Recipe
- Use Cold Ingredients: Always use cold ingredients before putting them in the machine – this saves time and improves texture.
- Minimum Liquid Needed: You need at least 16 oz of liquid for the machine to work properly.
- Peppermint Extract: Start with less peppermint extract and add more if needed – it’s very strong.
- Clean Immediately: Clean the machine right after using it while it’s still easy to wash.
- Adjust Thickness: You can adjust the temperature setting if you want thicker or thinner shakes.
- Prepare Cherries: Dry your cherries with paper towels before putting them on the whipped cream.
Serving Ideas for Ninja Slushie Shamrock Shake
Serve this Ninja Slushie Shamrock Shake in a tall clear glass so the green color shows. I like to add a big swirl of whipped cream and a cherry.
You can also drizzle a little chocolate syrup inside the glass before pouring the shake – it looks and tastes nice.
For a crunchy touch, add crushed cookies or a small cookie on the rim. A sprig of fresh mint on top gives a fresh look and tiny fresh mint aroma with each sip.
If you serve two or more shakes, use matching glasses and add a paper straw for a simple, pretty touch.
Kids and adults both enjoy a small sandwich cookie on the side to dip into the shake.
For an extra creamy finish, add a scoop of vanilla ice cream on top of the shake.
Make-ahead and Storage Tips
This shake is best fresh, but you can prepare parts ahead. Mix the milk, condensed milk, and peppermint extract in a pitcher and keep it in the fridge up to 24 hours.
Add Cool Whip and whisk right before putting in the Ninja SLUSHi to keep the texture light. If you pre-mix with Cool Whip, the drink can lose some airiness, so stir gently to keep it smooth.
The machine will keep your shake at the perfect temperature for up to 12 hours, so you don’t have to worry about it.
If the shake smells sour, has off flavors, or the whipped topping separates and looks grainy, throw it away. Also toss if the milk smells bad or there is any mold.
Ninja Slushie Shamrock Shake Recipe FAQs
1. Can I make this recipe without a Ninja Slushie machine?
Yes, you can use a regular blender but the texture won’t be exactly the same. Use a high-speed blender and blend everything until it’s smooth and creamy. You might need to stop and scrape down the sides a few times.
2. How do I make it less minty?
Start with just 1/2 teaspoon of peppermint extract instead of a full teaspoon. You can always add more but you can’t take it out once it’s mixed in.
3. Can I add booze for adults?
Yes, add a shot of Irish cream or vodka to make it grown-up. Mix in after the machine or before. I tried it for a party – smooth and fun. Don’t give to kids.
4. How do I get the perfect green color?
I usually start with 1/2 teaspoon of green food coloring and stir well. Add more drops if you want it brighter, but even a little gives it that fun St. Patrick’s Day look.
5. Why is my shake too thin?
If the shake turns out thin, it usually means the milk was too warm or there was too much liquid. I make sure the milk is cold and the Cool Whip is firm to get a thicker shake.
