There’s something magical about December in Australia. Half of us are melting in the heat, the other half are in denial and still putting the oven on for a full roast dinner, and all of us — every single one — are craving something festive and cold.
Enter my new obsession: the Ninja Slushie Eggnog Milkshake.
If you’ve been hunting for the perfect Christmas Ninja Slushie recipe, something that tastes like the holidays without feeling heavy or sugar-loaded, this is the recipe that will save you. It’s nostalgic, creamy, lightly spiced… and thanks to the Ninja, it becomes a frosty, sippable holiday drink that absolutely hits the spot on a warm December evening.
And the best part?
It only takes a couple of minutes to mix together, and the Ninja Slushie Maker does all the hard work while you pretend you’re organising the Christmas wrapping cupboard (we both know you’re not).
Why This Is the BEST Christmas Ninja Slushie Recipe
I’ve tried plenty of holiday slushie drink recipes over the years — frozen hot chocolate, candy cane frappes, gingerbread smoothies — but nothing beats eggnog as a slushie base.
Eggnog already brings:
– the creaminess
– the cinnamon/nutmeg warmth
– that classic Christmas flavour everyone recognises
And when you pour it into the Ninja Slushie Maker?
It transforms into a light, icy, ridiculously drinkable Christmas milkshake-slush hybrid.
It’s festive without being heavy.
It tastes indulgent without the post-dessert regret.
And honestly? It’s become my go-to whenever someone drops by during December and I need a treat that looks more impressive than the effort involved.
What You’ll Need
Just a handful of simple ingredients you probably already have during the holidays:
– 1 cup eggnog (store-bought or homemade — both work beautifully)
– 1½ cups full-cream milk (don’t skimp, it helps with texture)
– ¼ tsp ground nutmeg
– Optional: whipped cream, cinnamon sugar, crushed gingerbread, or a sprinkle of extra nutmeg
These ingredients are classic for any holiday slushie recipe, and the flavour payoff is huge.
1. Mix Everything Together
In a large measuring jug with a spout (trust me, it’ll make your life easier), whisk or stir together:
– eggnog
– milk
– nutmeg
A quick mix is enough.
Little tip:
Cold ingredients freeze faster in the Ninja, so pop them in the fridge for 20 minutes beforehand if you can.
2. Pour Into the Ninja Slushie Maker
Open the pouring hatch on your slushie maker and gently pour the mixture in.
Close the hatch, power on the machine, and select:
MILKSHAKE – START
Your Ninja will now start doing its little Christmas miracle.
3. Let the Ninja Churn and Freeze
This is where the magic happens. You’ll see the mixture begin to thicken, swirl, and slowly turn into that gorgeous icy milkshake texture.
The Ninja will beep loudly when the milkshake is ready — that’s your cue.
But here’s a pro tip for all my fellow texture-lovers:
Want it thicker? Hit the UP arrow to increase the freeze level.
One or two notches makes it extra cold and extra creamy.
4. Serve and Garnish
Once the Ninja Slushie Maker tells you it’s ready, pull the lever and watch the festive goodness flow into your glass.
Top with whipped cream and a dusting of nutmeg — it looks insanely pretty and tastes even better.
For extra Christmas sparkle, try:
– crushed gingerbread crumbs
– a drizzle of caramel
– a cinnamon stick
– mini marshmallows
– a gingerbread man perched on the rim
Pinterest will have nothing on you.
There are a million Christmas drink recipes out there, but this one checks every box for busy Aussie households:
Cold, refreshing and festive
Fast to prepare
Kid-friendly option (just skip alcoholic eggnog versions)
Perfect for entertaining
Ideal for “bring a dessert” moments
Ninja Slushie Maker friendly
Plus, it’s a total crowd-pleaser. People will ask for the recipe.
People will want seconds.
People will assume you put effort in.
You didn’t. We love that.
If your slushie is too runny:
Increase the freeze level and churn another 1–2 minutes.
If your slushie is too thick:
Add 2–3 tablespoons of milk and churn briefly.
If it never freezes properly:
Your eggnog may have been too warm — chill everything next time for best results.
If you want it sweeter:
Add a teaspoon of vanilla syrup or condensed milk.
If you want it more “Christmassy”:
Add an extra pinch of cinnamon or nutmeg.
This slushie is best served fresh, but you can prep the mixture in advance.
– Mix all ingredients in a jug
– Chill until needed
– Pour into the Ninja when guests arrive
The Ninja will always give you that perfect fresh Christmas slushie texture.
– Ninja Slushie Maker — the star of my December kitchen
– 4-cup Pyrex jug — makes whisking + pouring clean and easy
– Tall milkshake glasses — because presentation counts
– Reusable paper straws — cute, festive, and great for photos
Approximately 3 cups, depending on your freeze level — enough for 2–3 festive servings.
If you need to serve a crowd, simply double or triple the base mixture and freeze in batches.
