A tall glass of Ninja Slushie Butterbeer is the perfect drinks for hot days, movie nights, and for friends who enjoy a fun, fizzy treat.

As a big Harry Potter lover, I always dreamed of whipping up Butterbeer right in my kitchen. But getting that smooth, icy feel was tough for me.

Then I got my Ninja Slushi machine, and it changed everything. I’ve made many yummy drinks with it, and it never lets me down.

There’s no need to work hard; you just pour in the ingredients, press the button, and wait as the machine does all the hard work.

Today I want to share my best Ninja Slushie Butterbeer Recipe with you. This recipe tastes just like the one from the theme park.

Your family will love it. Best of all, anyone can make it at home.

Why you should try this Recipe

You should try this Ninja Slushie Butterbeer Recipe because it is easy, fast, and fun.

I make it when I want a special drink but do not want a lot of mess. The Ninja Slushie machine makes a smooth slush fast.

You do not need many tools or strange ingredients. Most of the items you can buy at a grocery store.

You can make a kid-friendly version or add a splash of rum for grown-ups. I like that you can make a small batch or many servings with the same steps.

You also get to be creative with the toppings. Try extra butterscotch, cookie crumbs, or a sprinkle of cinnamon.

This drink is worth trying because it tastes like the park drink but costs a lot less. You control the flavor and sweetness. You can make it lighter or richer.

Ninja Slushie Butterbeer Recipe Ingredients

Main Ingredients:

2 bottles (12 oz each) IBC Cream Soda – This is the best cream soda for this recipe. It has a rich vanilla flavor that’s not too artificial. If you can’t find IBC, use any good quality cream soda, but avoid A&W as it can taste too sour.
1 bottle (12 oz) Old Keg Premium Butterscotch Beer (non-alcoholic) – This gives the real butterscotch taste. You can find it at Costco or most grocery stores. If you can’t find this brand, any butterscotch soda works.
2 tablespoons butterscotch syrup – Use any brand you like. This adds extra butterscotch flavor. You can substitute with caramel syrup if needed.

For the Whipped Cream Topping:

1 cup heavy whipping cream – Must be cold for best results. Don’t use light cream as it won’t whip properly.
1 tablespoon powdered sugar – This sweetens the cream without making it grainy. Regular sugar works too but powdered is better.
1 tablespoon butterscotch syrup – Same as above, adds butterscotch flavor to the topping.
Pinch of salt – This brings out all the flavors. Don’t skip this small but important ingredient.

Recommended Equipment

Ninja Slushi machine (any model works) – Turns soda into perfect slushie texture
Large mixing bowl – For making butterscotch whipped cream
Hand mixer or immersion blender – Whips cream into fluffy peaks
Measuring cups and spoons – Gets the right amounts of ingredients
Tall glasses for serving – Shows off the slushy texture with room for toppings
Ice cream scoop (optional, for serving) – Makes scooping thick slushie easier

How To Make Ninja Slushie Butterbeer

Step 1 | Prepare Your Sodas

Open one bottle of IBC cream soda and one bottle of butterscotch beer. Mix them together in a large measuring cup. Add 2 tablespoons of butterscotch syrup and stir well. This mixture gives you the perfect balance of cream soda and butterscotch flavor.

Step 2 | Add to Ninja Slushie Machine

Pour the soda mixture into your Ninja Slushie machine. Make sure not to overfill it and follow your machine’s fill line. Close the lid tightly.

Step 3 | Start the Slushie Process

Turn on your Ninja Slushie machine. Select Slush button. The machine will mix and freeze your drink to the perfect slushy texture.

Step 4 | Make the Whipped Cream

While your Butterbeer is freezing, make the topping. Pour cold heavy cream into a bowl. Add powdered sugar, butterscotch syrup, and a pinch of salt. Use a hand mixer to whip until you get soft peaks. Don’t over-whip or you’ll make butter.

Step 5 | Check Your Butterbeer

After 15 minutes, check if your Butterbeer is ready. It should look like a thick slushie. If it’s too liquid, run the machine for a few more minutes. If it’s too thick, add a little more soda.

Step 6 | Serve and Enjoy

Scoop the frozen Butterbeer into glasses. Top each glass with a big spoon of butterscotch whipped cream. Serve right away with thick straws. The drink will start to melt quickly, so enjoy it fast.

Tips for Success

Chill the sodas first: Keep the cream soda and butterscotch beer in the fridge before making the slushie. Cold liquids freeze faster and maintain the drink’s fizz.
Use fresh bottles: Old soda can lose its bubbles, so new bottles give the best fizz and flavor.
Skip real butter: Avoid adding actual butter—it hardens in the cold and creates lumps. Syrup provides a smooth, sweet taste without issues.
Whip cream cold: Heavy cream should be kept in the fridge until ready to whip. Room-temperature cream will not fluff properly.
Clean the machine quickly: Rinse the Ninja Slushie machine immediately after use to prevent sticky buildup.

Ninja Slushie Butterbeer Serving Ideas

This frozen butterbeer pairs well with simple, comforting treats. I like to serve it with soft cookies, popcorn, or a warm brownie. The cold, creamy slush balances sweet baked goods.

For a party, set up a small snack tray with shortbread cookies, mini donuts, and chocolate-covered pretzels.

For serving, use tall glasses that show off the beautiful slushy texture.

Add thick straws so people can easily drink it. Put the butterscotch whipped cream on top right before serving.

You can also drizzle extra butterscotch syrup on the whipped cream for a fancy look.

Make This Recipe Ahead of Time

You can mix your cream soda and butterscotch syrup in a pitcher and chill it in the fridge for up to a day. Whip up your flavored cream topping and keep it covered until you’re ready to serve.

However, I don’t recommend making the actual slushie ahead of time. When you want to enjoy the drink, just pour the cold mix into your Ninja Slushie machine and let it run.

The fast-freeze cycle gives you fresh slush in minutes.

Ninja Slushie Butterbeer Recipe FAQs

1. Can I make this recipe without a Ninja Slushi machine?

Yes, you can make a version without the Ninja Slushi machine, but it won’t be exactly the same. Put your soda mixture in the freezer for about 2 hours. Every 30 minutes, take it out and stir it with a fork to break up ice crystals. You can also use a regular blender with ice, but add the ice slowly so you don’t water down the flavor.

2. Why does my butterbeer taste too sweet?

If your butterbeer is too sweet, try adding a small pinch of salt to balance the flavors. You can also use less butterscotch syrup next time.

Some cream sodas are sweeter than others, so you might need to adjust based on the brand you use.

3. Can I make this recipe with alcohol for adults?

Yes, you can add alcohol to make an adult version. Try adding 1-2 ounces of butterscotch schnapps or rum to each serving. Add the alcohol after the slushie is made, not before putting it in the machine.

Vanilla vodka also works well. Remember that alcohol doesn’t freeze the same way, so your slushie might be a little thinner.

4. Why can’t I use homemade butterscotch sauce in the slush?

This is important! Homemade butterscotch sauce usually has real butter. When you put it into the super-cold Ninja machine, the butter fat turns solid. It makes the slush grainy and separates.

Store-bought butterscotch syrup (like ice cream topping) doesn’t have butter, or uses different ingredients, so it works fine. Stick to syrup for the slush mix and the whipped cream topping.
