This homemade ninja slushi vanilla milkshake recipe uses only a few simple ingredients, but the final drink tastes almost like something you’d get from a restaurant.
I’ve made plenty of slushie drinks using my Ninja Slushi machine, and the results are always better than anything I can get from a store.
Summer means cool drinks become part of my daily life, and while you’ve probably had plenty of shakes before, this slushie has a creamy smooth texture you can make easily at home thanks to the Ninja Slushi machine.
It makes the vanilla milkshake slushie creamy and smooth every time, and the process is super easy. After a long, tiring summer day, sometimes I just feel lazy, but this quick slushie is perfect to take care of that thirst fast.
It’s simple, fun, and great to share with friends or family. Today, I’m sharing my copycat ninja slushi vanilla milkshake recipe.

Why You’ll Love This Recipe
You’ll love this ninja slushi vanilla milkshake recipe because it takes just five minutes to make. I use only four simple ingredients that you probably have in your kitchen right now.
The ninja slushi machine does all the mixing and makes the perfect creamy texture every time. No more running to expensive coffee shops when you want a good milkshake.
Ninja Slushi Vanilla Milkshake Ingredients
- 3 cups whole milk – Whole milk is used because it makes the milkshake creamy and rich. The fat in whole milk gives the best texture. 2% milk can be used as an alternative, but the taste won’t be as creamy. Skim milk should be avoided because it makes the milkshake too thin.
- 1.5 cups heavy whipping cream – This ingredient makes the milkshake thick and smooth like the ones from restaurants. Half-and-half can substitute, but the milkshake will be thinner. Light cream should not be used because it won’t give the right texture.
- 2 tablespoons sugar – Regular white sugar works best for this recipe. It dissolves easily and doesn’t change the color of the milkshake. Honey can be used instead, but only 1 tablespoon since honey is sweeter. Brown sugar will make the milkshake taste different, so stick with white sugar.
- 2 tablespoons vanilla extract – Pure vanilla extract gives the best flavor. Artificial vanilla shouldn’t be used because it tastes fake. If only artificial vanilla is available, use just 1 tablespoon instead of 2. Vanilla bean paste can also be used for extra flavor, but it costs more money.
Recommended Equipment
- Ninja Slushi machine – Makes the perfect creamy texture
- Large measuring cup (at least 4 cups) – For mixing all ingredients
- Long spoon or spatula – To stir ingredients together
- Tall glasses – Best size for serving milkshakes
- Straws – Makes drinking thick milkshakes easier
How To Make Ninja Slushi Vanilla Milkshake
Step 1 | Add the Whole Milk
In a measuring cup pour 3 cups of cold whole milk. Milk is kept in the back of the fridge where it stays coldest. Cold ingredients make better slushies because the machine works better with cold liquids.

Step 2 | Add Heavy Whipping Cream
Add 1.5 cups of heavy whipping cream to the same measuring cup with the milk. Pour it slowly so it doesn’t splash. The cream will mix with the milk naturally, but it will be stirred more in the next step.

Step 3 | Add Sugar
Now add 2 tablespoons of sugar to the milk and cream mixture. Use a regular measuring spoon, not a big serving spoon. Make sure to level off the sugar so too much is not added.

Step 4 | Add Vanilla Extract
Pour in 2 tablespoons of vanilla extract. This is what makes the milkshake taste amazing. Don’t skip this step because vanilla extract is what makes this recipe special.

Step 5 | Stir the Mixture
Take a spoon or spatula and stir everything together. Mix well so the sugar starts to dissolve. Stir for about 30 seconds to make sure everything combines nicely. The sugar should disappear into the liquid.

Step 6 | Pour Mixture into Ninja Slushi Machine
Open the ninja slushi machine and pour the mixture inside. Be careful not to overfill it. Most ninja slushi machines have a fill line, so don’t go past that mark. If there is leftover mixture, save it in the fridge for the next batch.

Step 7 | Secure the Lid and Turn On
Put the lid back on the machine and make sure it clicks into place. Press the power button to turn on the ninja slushi machine. The machine will start up and get ready to work.
Step 8 | Select the Milkshake Setting
Look for the ‘Milkshake’ option on the machine’s control panel. Each ninja slushi machine is a little different, but most have this setting. Press the milkshake button and let the machine do its work. This usually takes about 2-3 minutes.

Step 9 | Prepare to Serve
When the machine stops, the vanilla milkshake is ready. Open the lid carefully because sometimes there’s a little steam. Get glasses ready for serving. Use the dispenser button or lever to pour the milkshake into glasses. Fill each glass about 3/4 full and serve.

Recipe Perfection Tips
- Chill your glass in the fridge for 10 minutes before pouring the milkshake. It keeps the drink cold longer.
- Taste the mixture before pouring it into the machine. Add a bit more sugar if you like it sweeter.
- Clean the Ninja Slushi machine right after use to keep it working perfectly.
- For a thicker shake, add an extra ¼ cup of heavy cream.
What to Serve with Milkshake Slushie
This ninja vanilla milkshake slushie goes great with simple snacks that balance the sweet and cold.
I like to pair it with salty fries or potato chips – the crunch and salt cut through the creaminess nice.
For a meal, serve it next to a burger or grilled cheese sandwich; it’s like a diner treat at home. If you want light, fresh fruit like strawberries or bananas dip well, or cut them up and float on top.
Cookies are perfect too – chocolate chip or oatmeal ones dunk in the slushie for extra fun.
For dessert time, match it with pie or cake; the vanilla flavor fits any.
To serve, pour into glasses or cups right after making, add that green straw, and maybe a sprinkle of nutmeg on top for looks.
How To Store Leftover Properly
Milkshakes are best fresh, but if you have leftovers, you can keep them in the fridge for up to 24 hours.
Store in an airtight jar or bottle. When you’re ready to drink it again, give it a quick stir or blend.
For longer storage, freeze it in a sealed container for up to a month. Let it thaw in the fridge for a few hours before drinking.
If it becomes too icy, just give it a quick spin in the Ninja Slushi machine to bring back that smooth texture.
If it smells sour or has a strange taste, it’s best to throw it away.
Ninja Slushi Vanilla Milkshake Recipe FAQs
1. Can I make this without a Ninja Slushi machine?
Yes, you can use a blender instead, but the texture might not be as smooth. Add a handful of ice cubes to help get that slushie feel.
2. Why does my slushie melt fast?
Slushies melt quick because they’re icy. Serve in cold glasses to slow it. I chill my glasses in the freezer first. Drink soon after making. If it melts, stir and sip as a shake. Warm room makes it faster, so keep cool.
3. How can I make it less sweet?
Simply reduce the sugar or skip it entirely if your vanilla extract is already sweetened. You can also add more milk to balance the flavor.
4. Can I add other flavors?
Absolutely. Chocolate syrup, caramel sauce, or even a spoon of peanut butter blend in beautifully with vanilla. Just adjust sweetness to taste.
5. Can I double this ninja slushi vanilla milkshake recipe for a party?
You can definitely double this recipe, but check your ninja slushi machine’s capacity first. Most machines can handle double recipes, but you might need to make it in two batches for best results.
6. Is this recipe kid-friendly?
Yes. It’s perfect for kids since it’s sweet, smooth, and made from simple ingredients. Just keep portion sizes reasonable because of the sugar content.
