Quick Answer: How to Make a Ninja Slushi Oreo Milkshake
Combine whole milk, vanilla ice cream, and crushed Oreos directly in the Ninja Slushi vessel. Set the machine to the Milkshake preset and let it churn for about 5 to 7 minutes until thick, smooth, and perfectly blended. Serve immediately with whipped cream and extra cookie crumbles.
The Chemistry of Ninja Slushi Oreo Milkshake
The key to this creamy shake is all about temperature control and balance. The combination of milk and heavy cream gives the shake body, while granulated sugar boosts sweetness and smoothness. The Oreo cookies bring not only their iconic chocolately crunch but a hit of nostalgic flavor. When you pour this mixture into the Ninja Slushi machine and select the milkshake preset, the machine’s simple cooking mode keeps everything chilled while blending to a perfect consistency. No ice needed- just pure creamy goodness.

How to Make a Milkshake in the Ninja Slushi Machine
Making a milkshake in the Ninja Slushi is mostly hands-off. Start by whisking the milk, heavy cream, granulated sugar, and vanilla extract in a mixing bowl until the sugar fully dissolves. Regular granulated sugar works best here, since larger granules can leave the shake grainy. Pour the base into your Ninja Slushi, press the milkshake button, and let it chill and churn for 30 to 45 minutes. Stick with the preset rather than running it longer, because over-churning can make the texture icy. Once it’s thick and creamy, pour it into 6 glasses, top each one with crushed Oreo crumbs, and stir them in. Adding the cookies at the end keeps them from sinking or clogging your straw, so grab some thick shake straws and enjoy!
Recipe Troubleshooting
If your shake ends up too runny or thin, it’s usually because you didn’t churn long enough or because the cream and milk are out of balance.
Oreo cookies that sink straight to the bottom or clog up your straw. To avoid this, you can stir in extra crushed cookies just before serving, or use thick shake straws.
Some users over-churn and get an icy, grainy texture, so stick with the preset settings for best results. Another reason your texture is grainy is if the sugar wasn’t fully dissolved. Make sure you aren’t using a large-granule sugar like organic sugar, and whisk before pouring it into the machine.
Make sure your machine is cleaned correctly to ensure an even texture every time.
Some people think the texture is too inconsistent, especially if cookies are added too early or are too chunky- stir them in at the end for better distribution.
If you feel the Oreo flavor isn’t strong enough, try using Oreo crumbs instead of large chunks for more flavor per sip.
If your shake is too sweet, reduce the sugar by 2-3 tablespoons and taste-test.

Serving Suggestions
It’s no surprise that TikTok Oreo shake trends are going viral this year, and this recipe fits right in.

Whether you’re prepping a viral milkshake, planning a Fourth of July frozen treat, or need something cool on a hot day, this shake fits the bill. Expect to see it pop up more in the Ninja Slushi summer recipes rotation as people look for creamy cold drinks.
Serve in tall, chilled glasses for a diner-style feel. Top with whipped cream, a drizzle of chocolate sauce, and extra crushed Oreos. Want to go the extra mile? Rim the glass with chocolate and dip it in crushed cookies for an Instagram-worthy presentation. This shake pairs beautifully with burgers, fries, or a summer BBQ spread. Hosting a party? Serve it in mason jars with custom labels, or add colorful paper straws for a fun touch.
Beyond burgers and fries, this shake is perfect alongside brownies, chocolate chip cookies, or even as a decadent breakfast shake (no judgment!). It’s also a great dessert option for birthdays or movie nights. Use mason jars for a rustic look or mini glass bottles for parties.

Storage Tips
This shake is best enjoyed fresh, but can be refrigerated or frozen for up to 4 hours. Store in a covered pitcher or airtight jar, and give it a good stir before serving. You may have to thaw it out if you’ve left it in the freezer for too long.
Freezer– If you want to save the shake for later, freeze it in ice cube trays and re-blend (in a blender) with a splash of milk for a slushier version later.
Making Ahead– Mix the base ingredients ahead of time and keep chilled in the fridge. You can pour into your drink maker and churn when ready to serve. For parties, pre-crush your Oreo cookies and store them in a sealed container for last-minute mix-ins.
