Ninja Slushi Spiked Eggnog Ingredients
- Eggnog
- Alcohol/Liquor: The best one to use is going to depend on your vibe! Dark rum or bourbon work great because they both blend smoothly, freeze nicely, and won’t overpower the creamy base, just enhance it. Brandy, cognac, and whiskey also pair wonderfully with eggnog.
- Cinnamon and Nutmeg
Can I Make This With a Regular Blender
Yes, but you will need to add a lot of ice to get that thick texture, which may cause you to adjust the ratio of sugar/sweetener and/or eggnog. You will have to adjust to taste and what works for you.
How to Fix Error Messages Related to Alcohol
If you’ve ever tried whipping up a margarita, piña colada, or any frozen cocktail in your Ninja Slushi machine and ended up staring at an error message, or worse, a sad, watery mess. Trust me, I’ve been there. I went through all the trial and error so you don’t have to. Here’s the real reason it happens (and how to fix it).
- Alcohol and Freezing Don’t Mix Well – Alcohol doesn’t freeze like water, so if your drink is too strong, the machine can’t do its job. Too much liquor = no slush. The machine will either skip the shave or refuse to dispense altogether.
- Your Ratios Are Off – The Ninja Slushi needs balance. You’ve got to have the right mix of alcohol and water-based liquid. Too little liquid, and you’ll be scraping ice chunks. Too much, and it’ll pour out like a cocktail instead of a slushie.
- Thick Mixers Can Mess Things Up – Heavy juices, creamy ingredients, or thick syrups can slow the machine down and make your texture clumpy or uneven. Go lighter with those or mix them in after blending.
- Don’t Overfill It – There’s a reason the machine has fill lines, y’all. If you go over that max line, it’s going to struggle to freeze and dispense properly. Keep it in range for the perfect slush every time.
How to Make Error Free in the Ninja Slushi Machine
If your drink’s too boozy, the Ninja Slushi machine is gonna let you know. You’ll see the temperature lights start flashing one by one from the bottom up, the preset buttons blinking like crazy, and then it’ll start beeping at you every minute for 15 minutes. That’s your cue to cool it on the alcohol and add a splash of something lighter like water or sparkling water to balance things out.
- Keep It at 1–1.5 oz Alcohol per Serving – Anything more, and your drink won’t freeze up right.
- Add a Little Extra Liquid – Water, juice, or mixer helps it blend smooth and thick instead of icy or runny.
- Start with Cold Ingredients – Pre-chilled liquids help the mix freeze faster and stay slushy longer.
- Go Easy on Thick Syrups or Creamy Stuff – If you use them, thin them out with water or juice so the machine doesn’t struggle.
- Respect the Fill Line (64 oz Max) – Overfilling just throws everything off. Stay in that sweet spot for the perfect pour every time.

Dark or spiced rum is the classic choice and blends beautifully with the creamy eggnog flavor. Bourbon adds a warm, oaky note, and brandy gives it a smooth, traditional finish. You can even mix them if you like a stronger, layered flavor.
