If you grew up sipping Orange Julius at the mall, get ready, because my Ninja Slushi version tastes just like you remember, but colder, creamier, and way easier to make at home. 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.
