Ninja Slushi Orange Milkshake/Julius Ingredients
To make this delightful frozen treat, you’ll need the following simple ingredients:
- Orange Juice: The star of the show! Freshly squeezed is always best for the most vibrant flavor, but store-bought works too.
- Milk: Any milk will do, including plant-based options like almond milk, soy milk, or oat milk. However, whole milk delivers the richest, creamiest texture.
- Sugar or Sweetener: Adjust the sweetness to your preference. Granulated sugar, agave nectar, honey, or sugar substitutes like stevia or monk fruit are all great choices.
- Vanilla Extract: A touch of vanilla enhances the overall flavor profile and adds a warm, comforting note. Use pure vanilla extract for the best results.

How to Make Ninja Slushi Orange Julius
Detailed measurements and complete instructions can be found in the recipe card at the bottom of this post. Here’s a quick overview of the process:
- Combine: In a separate container, combine the milk, sugar/sweetener, and vanilla extract. Stir well until the sugar or sweetener is completely dissolved. This step ensures a smooth and even flavor throughout the final product.
- Pour: Pour the milk mixture and the orange juice into your Ninja Slushi Machine. Make sure not to overfill the machine.
- Process: Press the milkshake button or the appropriate setting for frozen drinks. Allow the machine to work its magic! The processing time can vary from 15 to 45 minutes, depending on factors like the sugar content and the initial temperature of the liquids.
- Dispense: Once the cycle is complete and the mixture has reached your desired consistency, place a cup under the self-serve spout and gently pull the handle to dispense your creamy, dreamy Orange Julius.



Substitutions and Variations
Want to add your own twist? Here are some delicious variations and substitutions to try:
- Fruity Fun: Experiment with adding other fruits like pineapple, peach, watermelon, or strawberries for a unique flavor combination.
- Sweetener Swap: Instead of granulated sugar, try honey, agave nectar, or maple syrup for a natural touch.
- Extra Creamy: Add a scoop of vanilla ice cream or frozen yogurt for an even richer and more decadent treat.
- Citrus Burst: Enhance the citrus flavor by adding a splash of lemon or lime juice.
- Spice it Up: A pinch of ground ginger or cinnamon can add a warm and comforting spice note.

Frequently Asked Questions and Recipe Pro Tips
- Can I make this without the Ninja Slushi machine?
- Yes, but the texture will be different. A blender with ice can work, but it won’t achieve that signature creamy, frozen slush consistency.
- Does this taste like the classic mall Orange Julius?
- Absolutely! It’s creamy, citrusy, and smooth, with that characteristic sweet vanilla finish that takes you right back to the mall.
- Can I make it dairy-free?
- Yes, simply use your favorite dairy-free or plant-based milk alternative.
- Can I use bottled orange juice?
- Yes, any orange juice you enjoy will work. However, if you opt for sugar-free orange juice, you’ll need to add sugar or a sugar substitute like monk fruit or allulose to ensure the machine processes correctly.
- Can I make this boozy?
- Definitely! Add a splash of vodka, vanilla vodka, rum, or orange liqueur for an adult twist.
- Can I reduce the sugar?
- Yes, adjust the amount of sugar or sweetener to your personal taste preference. You can also substitute with a sugar-free sweetener.
- How long does it take to freeze in the Ninja Slushi?
- The freezing time typically ranges from 15 to 20 minutes, depending on the initial temperature of your ingredients. Starting with chilled ingredients will speed up the process.
- Can I prep the mix ahead of time?
- Yes! You can mix all the ingredients and refrigerate them for a few hours before freezing. This allows the flavors to meld together even further.

I’ve been running this machine since it dropped, so trust me when I say I’ve tested the ratios, fixed the mistakes, and dialed this recipe all the way in. This orange milkshake freezes perfectly, blends silky smooth, and delivers that sweet citrus-vanilla vibe every single time.
Ingredients:
- 3-4 cups orange juice (Use less orange juice for less orange flavor and more (4 cups) for more orange flavor.)

- 1 teaspoon vanilla extract
Equipment:
- Ninja Slushi Frozen Drink Machine
Instructions:
- Combine milk, sugar/sweetener, and vanilla extract before adding to the Ninja Slushi Machine. Stir to ensure the sugar/sweetener completely dissolves.
- Pour the mixture along with the orange juice into your Ninja Slushi. Press the milkshake button.
- Allow the machine to process. Let the machine run for 15-45 minutes, depending on the sugar content and temperature of the liquid.
- Once the cycle is complete, place a cup under the self-serve spout and pull the handle to dispense the milkshake.
