If you’ve ever wanted to make a McFlurry at home that actually tastes like the real deal, I got you, friend. This Ninja Slushi McFlurry hits hard. It’s thick, creamy, and packed with mix-ins that won’t sink to the bottom. I’ve been testing frozen drinks and desserts in this machine since day one, so trust me when I say this recipe works every single time. No runny mess, no icy texture, just that perfect spoonable McFlurry magic, right from your kitchen.

How to Make Ninja Slushi McFlurries
Detailed measurements and full instructions can be found in the recipe card at the bottom of this post.
- In a large mixing pitcher or bowl, whisk together the milk, granulated sugar or sweetener, and vanilla to break up any clumps. Whisk until fully combined.
- Pour the mixture into your Ninja Slushi. Press milkshake for the Ninja Slushi.
- Allow the machine to process.
- Consider a large glass for serving because it will turn out really thick and creamy. Once the cycle is complete, place a cup under the self-serve spout and pull the handle to dispense about half of the McFlurry. Sprinkle in half of the Oreos for that serving, and stir. Continue to fill up the milkshake. Add the remaining Oreos and stir.

Troubleshooting Tips if You Have Problems with the Machine
- Check your liquid ratio: If it’s too thick, your machine’s gonna fight you. Add 1–2 tablespoons of milk or water, give it another go, and let it work its magic.
- Make sure everything’s cold: That base needs to be chilled-chilled. If it went in lukewarm, pop it in the fridge or freezer for a bit before trying again.
- Check for ice build-up: If it’s freezing weird or looks uneven, it might’ve gotten too cold in one spot. Let it sit for a minute, give it a gentle stir, and restart.
- Double-check the setup: Make sure everything’s locked in, the lid, paddle, all of it. If something’s off-kilter, the machine won’t run right.

What if I don’t have the Ninja Slushi?
You can still make a version using a blender or food processor, but it won’t have that same soft-serve texture the machine creates. You will have to add ice to the blender to thicken up the drink. From there you may have to adjust the sweetness because the ice may dilute it some.
