Let’s talk about a classic treat with a frozen twist: the Vanilla Root Beer Float Slushie.
Imagine all the creamy, nostalgic flavors of a root beer float—but icy, thick, and super refreshing.

Flat root beer is actually perfect here, so don’t worry if your bottle lost its fizz! Ready in minutes, and it tastes just like the best part of summer.
Why I Love This Recipe
This recipe brings back so many memories. I grew up loving root beer floats, and making it into a slushie just makes it even more fun and satisfying. Here’s what I love about it:
- So easy: Three ingredients, one blender, that’s it!
- Super creamy and cold: The slushie texture takes it to a whole new level.
- Real vanilla flavor: A splash of vanilla brings out all the classic float vibes.
- You can add ice cream or not: It’s great both ways.
- Nostalgic, but with a twist: It’s like sipping on a classic float and a snow cone at the same time.
Every time I make one, it’s a throwback to sitting outside in the sun, float in hand, ice cream melting just a little bit into the soda. So simple and so good!

Why This Recipe Works (Quick Science)
- Flat root beer blends up smooth and icy—no crazy fizz to mess up your blender!

Common Mistakes
- Using bubbly soda: The blender will overflow—make sure it’s flat!
- Adding too much ice: Can water it down and make it less creamy.
- Skipping the vanilla: It really takes it from “root beer slushie” to “root beer float slushie.”
- Not chilling your ingredients: Warm root beer melts the ice too quickly.
What to Serve With
- Burger and fries
- Hot pretzels
- Salty popcorn
- Grilled cheese or deli sandwiches
- Chocolate chip cookies
Pro Tips
- Chill your root beer and ice cream: Cold ingredients make the thickest slush.
- Use good vanilla: Real extract gives the best float flavor.
- Add ice cream last: For the creamiest result, blend it in at the end or use it as a topper.
- Serve right away: The texture is best when it’s just blended!
- Try with different sodas: Works with cream soda or cola, too.
Tools You’ll Need
- Blender
- Measuring cups and spoons
- Ice cream scoop (if using ice cream)
- Glasses for serving
- Spoon or spatula
Substitutions & Variations

Make Ahead Tips
- Flat and chill your root beer ahead of time.
