Ninja Slushie Wendy’s Frosty Recipe
Ninja Slushie Wendy’s Frosty Recipe is one of the easiest and tastiest frozen treats I’ve ever made at home.
I grew up loving a Wendy’s Frosty and I had no idea making a Frosty at home could be this easy. Now I have the Ninja Slush Machine to make frozen drinks at home.
I’ve used the slushie to make milkshakes lots of times and they come out really good. I was curious if maybe I could use it to make a Wendy Frosty so the consistency would be more like a soft serve.
This whole process was so easy and used only three ingredients. Simply mix all three ingredients with a whisk until they’re well combined. Then add to the machine and it does all the work.
Summer afternoons are perfect for this creamy treat. Those hot days when you want something cold and sweet but don’t want to drive to the store.
A Wendy’s Frosty Recipe is that thick, creamy chocolate drink that’s somewhere between a milkshake and ice cream. The Ninja Slushie turns this recipe into a smooth and creamy texture that tastes just like the real thing.
Today, I’m sharing my full Ninja Slushie Wendy’s Frosty Recipe, so you can try it at home.

Why You’ll LOVE This Recipe
You’re going to love this recipe because it’s quick, fun, and only needs three ingredients you can grab from any store.
No special powders, no long cooking process, just chocolate milk, condensed milk, and whipped cream.
The Ninja Slushie takes care of the texture so you don’t have to worry about ice chunks or runny drinks.
It also tastes almost identical to the real Wendy’s Frosty. You get that chocolate flavor that’s not too sweet, the creamy body that feels like soft serve, and the satisfaction of making it at home.
You’ll save money, skip the drive-thru, and enjoy it anytime you want.
Ninja Slushie Wendy’s Frosty Ingredients
- 4 cups chocolate milk – This is the base of the Frosty. I like using whole chocolate milk because it gives the richest flavor, but you can also use 2% or almond milk for a lighter version. If you want a deeper chocolate taste, mix in a little cocoa powder.
- 7 oz sweetened condensed milk – This thick and sweet milk is what makes the Frosty creamy and smooth. It also adds sweetness, so you don’t need extra sugar. If you don’t have it, you can swap with evaporated milk plus sugar, but the texture won’t be quite the same.
- 4 oz whipped cream – This makes the Frosty light and fluffy. You can use homemade whipped cream or even the kind from a can. For a dairy-free option, coconut whipped cream works too.
How To Make Ninja Slushie Wendy’s Frosty
Step 1 | Pour Chocolate Milk
Take your mixing bowl and pour 4 cups of chocolate milk into it. Use a measuring cup to get the exact amount.

Step 2 | Add Sweetened Condensed Milk
Next, add 7 oz of sweetened condensed milk to the chocolate milk. Open the can and measure out exactly 7 oz. You can save the rest in the fridge for another batch later.

Step 3 | Add Whipped Cream
Add 4 oz of whipped cream to the mixture. If you’re using a container of whipped cream, measure it out carefully. Fresh whipped cream works best, but store-bought is fine too.

Step 4 | Mix Ingredients
Now comes the fun part – whisking everything together. Use a whisk or large spoon to mix all three ingredients until they look smooth and well combined. This should take about 2-3 minutes of mixing. Make sure there are no lumps of whipped cream left.

Step 5 | Pour Into Ninja Slushi Maker
Pour the mixture into your Ninja Slushi maker. Fill it up to the fill line but don’t overfill it. The machine needs some space to work properly.

Step 6 | Select Milkshake Setting
Select the “Milkshake” setting on your Ninja Slushi maker. This setting is perfect for getting that Frosty texture. Let the machine run for the full cycle. This usually takes about 15-20 minutes.

Step 7 | Serve and Enjoy
Your homemade Wendy’s Frosty is ready to serve. Use an ice cream scoop or large spoon to serve it in glasses or bowls. Enjoy right away while it’s at the perfect temperature.

Helpful Tips for Perfect Texture
- Use Cold Ingredients: Use cold ingredients for faster results — chill your chocolate milk and other ingredients in the fridge before mixing.
- Mix Well Before Chilling: Make sure all your ingredients are well mixed before putting them in the machine.
- Keep Equipment Clean: Clean your Ninja Slushi maker before and after use for the best taste.
- Adjust If Too Thick: If it’s too thick, add a splash more chocolate milk.
- Adjust If Too Thin: If it’s too thin, add a bit more whipped cream.
- Keep Machine Running: Don’t turn off the machine until you’ve served all the Frosty to avoid a foamy texture.
- Serve Quickly: Serve within 30 minutes of the machine finishing for the best texture.
Best Pairings for Wendy’s Frosty
This Frosty works with many simple snacks. I love it with a warm cookie.
The mix of hot and cold makes a nice contrast. It is also great with fries or a plain burger for a classic combo, but you can pair it with fresh fruit for a lighter note.
For a fun treat, serve the Frosty with a few small cookies on the side and a tall straw.
Kids like it with sprinkles. You can also add a small shot of espresso for a grown-up twist.
Use small scoops of ice cream on top to make a float. The Frosty is rich, so small sides work best.
Storage and Make-Ahead Process
This Frosty is best served fresh right from the Ninja Slushie because that’s when it’s soft and creamy. But you can store extras too.
Pour leftovers into an airtight container and freeze. When you’re ready to enjoy it again, let it sit at room temperature for about 10–15 minutes. It will soften and be ready to scoop.
Try not to keep it in the freezer for more than 2–3 days, because the texture can turn icy after that.
If it looks grainy or has freezer burn, it’s better to make a fresh batch. Since it only takes a few minutes, I usually make it right when I want one.
Ninja Slushie Wendy’s Frosty Recipe FAQs
1. Can I make this without a Ninja Slushie?
Yes, you can. Blend the mixture in a regular blender, then freeze it for about 2 hours, stirring every 30 minutes to keep it creamy. It won’t be as smooth as the Ninja Slushie version, but it still works.
2. Can I use regular milk instead of chocolate milk?
You can use regular milk, but you’ll need to add cocoa powder and sugar to get the chocolate flavor. Chocolate milk is easier since it’s already flavored.
3. Why does my Frosty come out runny?
Usually, it means the mixture wasn’t cold enough. Make sure the milk and cream are chilled before mixing. Also, the Ninja Slushie needs time to fully process the drink.
4. Can I add other flavors to this recipe?
Sure, you can add other flavors to this recipe for fun twists. For vanilla, mix in a teaspoon of vanilla extract before whisking. Or for mint, add a drop of mint extract and maybe green food color. Peanut butter fans can stir in a spoonful of smooth peanut butter. I tried strawberry by using strawberry milk instead of chocolate – it comes out pink and fruity.
5. Why is my Frosty too hard after freezing?
If you freeze the Frosty fully, it will become hard like ice cream. To fix this, let it sit at room temperature for 10–20 minutes, then stir or blend to soften. You can also scoop it into the Ninja Slushie maker and run the milkshake setting briefly to return it to soft serve style.
