Ingredients in Homemade Root Beer Floats

Root Beer – Of course, we can’t make a root beer float without a bottle of root beer! To make two floats you’ll want to have about 16 ounces of soda. Feel free to use your favorite brand of root beer. I think each has its own special flavor, and you can sometimes find small-batch root beer from local brewers that are super tasty.

Vanilla Ice Cream – The classic flavor for ice cream floats is vanilla. It really enhances the spicy sweetness of root beer to create a delicious creamy drink. You should try a root beer float with homemade vanilla bean ice cream, or easy no-churn vanilla ice cream. You can pick up a carton of your favorite ice cream at the store too.

Garnishes – These are optional, but I like to top all of my ice cream desserts with whipped cream and maraschino cherries! I put this combo on floats, sundaes, and milkshakes too.

How to Make a Root Beer Float

  1. Place two glass beer mugs in the freezer and let them sit for at least 20 minutes so that they are cold and frosty.
  2. Remove the mugs from the freezer and fill them each with 3 scoops of vanilla ice cream.
  3. Top each mug with about 8 ounces of root beer, taking care not to overfill the glasses.
  4. Pipe or dollop whipped cream on top of the floats.
  5. Then add a maraschino cherry garnish.
  6. Serve immediately, and with a straw.

Tips for Making the Best Root Beer Float

Use quality ingredients – When making floats at home, you’ll want to make sure you are using high-quality ingredients for the best outcome. Use homemade or high-quality ice cream, and be sure to use a root beer that you enjoy drinking.

Chill out – It’s very important to start with chilled ingredients. Keep the root beer in the fridge, and the mugs and ice cream in the freezer until you are ready to make the floats.

Lighten it up – Diet root beer can be used if you want to reduce the calories in your dessert.

Pour slowly – This is the trick to making a float! Adding soda to ice cream too quickly will cause your float to foam up too much. Take your time, and pour slowly.

Make Extra – Feel free to make more than two root beer floats! Pick up a 2-liter so that you have enough to satisfy a crowd. Root beer floats are fun at kids’ parties, or as a dessert to share with your family.

History of the Root Beer Float

The credit for creating the Root Beer Float is given to the owner of a brewing company in the Colorado mountains, Frank J. Wisner.

Frank is said to have been inspired by nature and designed the root beer float to feel like snow-covered mountains.

This happened back in 1893, which means that we have been enjoying root beer floats in America for almost 130 years!

Fun Float Variations

Chocolate Root Beer Float – Use scoops of chocolate ice cream in your float instead of vanilla for an extra decadent treat. A drizzle of chocolate syrup is a must too.

Frozen Root Beer Float – For a slushy treat that kids will love, combine root beer, ice cream, and ice cubes in a blender and pulse until icy.

Hard Root Beer Float – For adults only, pick up a few bottles of alcoholic root beer and make some super creamy cocktails.

What Is the Best Root Beer for Root Beer Floats?

You truly can use any type of root beer to make a float, but I suggest choosing one that has lots of rich, spicy flavor.

Commonly available brands include A&W Rootbeer, Barq’s, and Mug.

Look for six packs of bottled root beer too. These are a bit more expensive but typically super delicious. IBC, Dad’s, Sprecher, and Stewart’s are all good choices.

Easy Traditional Root Beer Float

Yield: 2 Servings
Prep Time: 5 minutes
Chilling/Freezing Time: 20 minutes
Total Time: 25 minutes

An easy recipe for a delicious Root Beer Float features a frosty mug of root beer mingled with scoops of creamy vanilla ice cream.


  • 6 scoops vanilla ice cream
  • 16 oz root beer
  • ¼ cup whipped cream topping
  • 2 maraschino cherries


  1. Place two beer mugs or milkshake glasses in the freezer for 20 minutes. 
  2. Place 3 scoops of vanilla ice cream in each mug. 
  3. Top each mug with 8 oz of root beer, making sure that the mug does not overflow. 
  4. Pipe or dollop whipped cream topping on top of the root beer float. 
  5. Garnish with a maraschino cherry. 
  6. Serve immediately.


  • Keep the ice cream in the freezer until just before ready to scoop. The root beer will melt the ice cream quickly. 
  • Make sure the root beer is chilled before using. Cold ingredients will help prevent the ice cream from melting too quickly. 
  • Technically, all you need for a root beer float is vanilla ice cream and root beer. You don’t have to top your root beer float with whipped cream and a cherry, but I think it’s a fun way to take your root beer float to the next level!
  • I used two 16 oz beer mugs, which was the perfect size to fit 2-3 scoops of ice cream and 8 oz of root beer. Depending on the size of your glasses, you may need to adjust the amount of root beer and ice cream in each glass. 
  • I personally like to add the ice cream first and then pour the root beer on top of the ice cream. This way, you will know when to stop pouring the root beer and there is less mess. However, you could pour the root beer first and top with scoops of ice cream if you prefer.
