Root Beer Float Recipe: Few things bring childhood memories rushing back like a frosty, foamy root beer float.
This classic American treat blends the creamy richness of vanilla ice cream with the fizzy kick of root beer for a sweet and satisfying combo that’s perfect any time of year.
Whether you’re hosting a party, cooling off in summer, or just craving something nostalgic, this guide will walk you through exactly how to make the perfect root beer float.
What is a Root Beer Float?
A root beer float is a simple dessert drink made by combining scoops of vanilla ice cream with chilled root beer. When poured together, the carbonation in the soda reacts with the fat in the ice cream, creating a thick, creamy foam that overflows the glass with frothy goodness.
Also known as a “black cow”, the root beer float isn’t just a drink—it’s a whole experience. You sip a little, scoop a bit, slurp the foam, and repeat. It hits multiple textures and temperatures in every mouthful.
History of the Root Beer Float
The root beer float has a pretty cool backstory. It was invented in 1893 by Frank J. Wisner, a Colorado mining baron. Inspired by the snowy peaks of Cow Mountain, Wisner thought the white-capped mountains looked like ice cream floating in soda. So he did what any food-loving genius would do—he mixed vanilla ice cream with root beer and gave it to the local kids. The rest is fizzy history.
Over the decades, root beer floats became a staple at diners, soda fountains, and summer picnics. They’ve stood the test of time for one reason—they’re ridiculously good.

Ingredients You’ll Need
You only need two core ingredients to make a classic root beer float, but a few extras can really elevate it.
Essential Ingredients:
- Vanilla ice cream – 2 large scoops per glass
- Root beer – About 1 cup (cold and fizzy)
Optional Toppings:
- Whipped cream
- Maraschino cherry
- Chocolate syrup
- Crushed nuts
- Sprinkles
Ice Cream Selection Tips
Choosing the right vanilla ice cream is key. Here are a few pointers:
- Premium vanilla – Look for ice cream with real vanilla beans for rich flavor.
- Avoid light or low-fat – They tend to melt too fast and don’t give a creamy foam.
- Try custard-style – French vanilla or frozen custard gives that extra luxe mouthfeel.
Choosing the Right Root Beer
Not all root beers are created equal. Look for:
- High-quality craft brands – Brands like IBC, Boylan’s, or Barq’s offer bold, spicy flavors.
- Cold and fresh – Chill your root beer before using for maximum foam.
- Avoid diet sodas – They can taste flat and lack that classic sweetness.
Equipment You’ll Need
No fancy gear needed, but here’s what helps:
- Tall glasses – Preferably frosted
- Ice cream scoop
- Long spoon – For stirring and scooping
- Paper towels – In case it gets messy (it will!)
Preparation Tips Before You Start
To get the best experience:
- Freeze your glasses – It helps slow the melting.
- Work quickly – The foam builds fast once the root beer hits the ice cream.
- Set up your toppings – Have them ready before pouring.
Trust us, a little prep makes a big difference.
Step-by-Step Guide to Making the Perfect Root Beer Float
Let’s dive into the most important part: the step-by-step guide to building the perfect root beer float.
Step 1: Chill Your Glasses
Pop your tall soda glasses into the freezer for at least 15-20 minutes. This keeps the ice cream from melting too quickly and makes everything extra frosty.
Step 2: Add Ice Cream
Take your scoop and drop 2 generous scoops of vanilla ice cream into the bottom of the glass. Don’t press them down—just let them sit like soft clouds, waiting for a fizzy bath.
Step 3: Pour the Root Beer Slowly
Tilt the glass slightly and pour the cold root beer slowly down the side. This reduces the risk of overflow and helps preserve the bubbles. Pour until the glass is about 3/4 full.
Step 4: Let It Foam
Watch the magic happen! The carbonation reacts with the ice cream fat, creating that signature foam. Give it a moment to settle, then top off with a little more root beer if needed.
Step 5: Add Toppings (Optional)
Here’s where you can have fun. Add a swirl of whipped cream, a bright red cherry on top, or even a drizzle of chocolate syrup. Make it yours.
Step 6: Serve and Enjoy
Stick a straw and a spoon into the glass and serve immediately. Sip, scoop, and smile.
Common Mistakes to Avoid
Even though a root beer float is simple to make, a few common slip-ups can mess with the experience. Here’s what to watch out for:
- Pouring too fast – This causes the foam to overflow quickly and may leave you with a sticky mess. Always pour slowly and at an angle.
- Using warm root beer – Warm soda flattens the fizz and melts the ice cream faster. Chill it well ahead of time.
- Overfilling the glass – Leave room for foam. It’s better to top off than to clean up a spill.
- Poor quality ice cream – Go for rich, creamy varieties. Cheap or icy ice cream can make the float taste flat.
- Using a small glass – Always go for a tall one. The float needs space to breathe, foam, and swirl.
Avoid these and your float will be nothing short of flawless.
Tips for Making the Creamiest Root Beer Float
Want to level up your float? These tips will give you that dreamy, creamy consistency:
- Use frozen scoops – Let your ice cream sit in the freezer for a few extra minutes before scooping. This helps maintain its form when the soda hits.
- Add root beer in stages – Pour half, wait for the foam to settle, then top it off. This gives a balanced mix of creaminess and carbonation.
- Try a splash of cream – A tablespoon of heavy cream added just before serving creates a velvety texture.
- Layer your ingredients – Some people add ice cream, then a little root beer, then more ice cream, and finish with root beer. It’s like a fizzy parfait.
- Stir gently – Give a light swirl with a spoon if you want a float that drinks more like a shake.
Variations of Root Beer Floats
The original is unbeatable—but that doesn’t mean you can’t get creative! Here are some fun twists to try:
Classic Twist
- Swap vanilla ice cream for chocolate or coffee ice cream.

FAQs about Root Beer Float Recipe
1. Can I make a root beer float with non-dairy ice cream?
Absolutely! Try almond, oat, or coconut milk-based ice creams. They pair wonderfully with root beer, especially when frozen well beforehand.
2. Why does the float foam so much?
It’s a reaction between the carbonation in the soda and the fats in the ice cream. Pouring slowly helps manage it.
3. Is it okay to make floats in advance?
Not really. They’re best made fresh, as the ice cream melts quickly and the soda loses its fizz. But you can prep ingredients ahead.
4. Can I use diet root beer?
You can, but expect less foam and sweetness. Diet sodas have different carbonation profiles that don’t react the same way.
5. What’s the best ice cream flavor besides vanilla?
Chocolate is a popular choice, but caramel swirl, coffee, or even mint chocolate chip can make fun alternatives.
