Made the Cookies and Cream Shake in the Ninja Slushi on a rainy Friday and it turned into a whole movie night. Whole milk, heavy cream, vanilla syrup, and crushed chocolate sandwich cookies on the MILKSHAKE preset, and it comes out thick with real cookie chunks instead of that fake speckled stuff. My son picked out every visible cookie piece with his spoon first, then drank the rest. Crush the cookies by hand and leave some bigger chunks. Powder-fine cookies just turn the whole shake gray, but real pieces give you something to actually chew.

Tips
- Pour your liquid base at room temperature into the Slushi bowl, then let the machine churn for 20-60 minutes depending on your kitchen temperature and desired thickness.
- Crush your chocolate sandwich cookies into varied sizes, from fine crumbs to small chunks, so you get texture differences throughout the shake.
- Add the crushed cookies about halfway through the churn cycle so they stay mixed in without settling to the bottom.
Variations
- Swap vanilla syrup for chocolate syrup and use half the crushed cookies for a less sweet, more cookie-forward version.
- Add 2 tablespoons of peanut butter to your liquid base to turn it into a cookies and cream peanut butter shake.
- Use chocolate chip cookies instead of sandwich cookies for a different flavor profile and crunchier texture.
FAQ
- Can I use less heavy cream to make it lighter?
- Yes, replace some heavy cream with more whole milk (use up to 3 parts milk to 1 part cream) and it will still churn into slush, just a bit less creamy.
- Why is my shake not getting slushy after an hour?
- Check that your Slushi bowl is properly seated in the machine and the base liquid is cold from the fridge, not room temperature, which takes longer to freeze.
- What if I don't have vanilla syrup on hand?
- You can use 2-3 tablespoons of vanilla extract mixed into your milk and cream, or skip it and add extra crushed cookies for sweetness instead.
- How long can I keep the finished shake in the machine?
- It's best served right away from the tap while it's slushy, but you can keep it in the Slushi bowl for up to 30 minutes before it starts to separate.
