I love making boozy root beer floats because they bring together two of my favorite things: creamy vanilla ice cream and fizzy root beer with a little grown-up twist. It’s a fun treat that feels special but is super simple to put together. I can’t wait for you to try it and enjoy that perfect mix of sweet and spicy!
Most of the ingredients are probably already in your kitchen or easy to find at the store. The spiced rum is the only one you might need to pick up if you don’t have it on hand. When you go to the supermarket, look for a bottle labeled "spiced rum"—it adds a warm, flavorful kick that makes this float extra tasty. The rest, like vanilla ice cream and root beer, are pretty common and easy to grab.
Ingredients For Boozy Root Beer Floats Recipe
Vanilla ice cream: Creamy and sweet, this is the base of the float that makes it smooth and delicious.
Root beer: A fizzy, sweet soda with a unique flavor that pairs perfectly with vanilla ice cream.
Spiced rum: Adds a warm, spicy flavor that gives the float its boozy twist.
Whipped cream: Optional, but it adds a light, fluffy topping that makes the float look and taste extra special.
Maraschino cherries: Also optional, these bright red cherries add a pop of color and a sweet finish on top.
Technique Tip for This Recipe
One of the fun parts of making these boozy root beer floats is adding the root beer over the vanilla ice cream. Pouring the soda slowly is a little trick that helps keep your float from bubbling over and making a mess. Here’s how you can do it:
- Hold your glass at a slight angle, about halfway tilted.
- Pour the root beer gently down the side of the glass instead of straight in the middle.
- Once the glass is about three-quarters full, slowly bring it back upright and finish pouring.
Doing this helps the root beer mix with the ice cream without creating too many bubbles or foam. If you pour too fast or straight down, the soda fizzes up quickly and can spill over the sides, which is messy and wastes some of your drink. Taking your time with this step makes the float look nicer and taste better because the flavors blend smoothly.
When I first made floats, I was so excited that I poured the root beer too fast and ended up with sticky soda all over the counter. Now, I always remind myself to tilt the glass and pour slowly—it’s a small step that makes a big difference. Also, if you want to get creative, try using a straw to stir gently after adding the spiced rum so everything mixes just right without losing the fizz.
This little pouring trick is a simple way to keep your boozy root beer floats looking perfect and tasting just right every time.
Suggested Side Dishes
Alternative Ingredients
vanilla ice cream - Substitute with coconut milk ice cream: Coconut milk ice cream provides a creamy texture and a subtle coconut flavor that complements the root beer.
root beer - Substitute with ginger beer: Ginger beer offers a spicy kick and a similar effervescence, making it a great alternative to root beer.
spiced rum - Substitute with bourbon: Bourbon has a rich, caramel-like flavor that pairs well with the sweetness of the ice cream and the spice of the ginger beer.
whipped cream - Substitute with coconut whipped cream: Coconut whipped cream is a dairy-free alternative that adds a light, tropical note to the float.
maraschino cherries - Substitute with fresh cherries: Fresh cherries provide a natural sweetness and a more robust flavor compared to maraschino cherries.

How to Store or Freeze Your Floats
- To keep your vanilla ice cream in prime condition, store it in the coldest part of your freezer. This ensures it remains creamy and scoopable for your next dessert adventure.
- If you have leftover root beer, seal it tightly in its original bottle or transfer it to an airtight container. This will help maintain its fizzy goodness for future beverages.
- For the spiced rum, store it in a cool, dark place. This preserves its rich flavors and ensures it's ready to add a kick to your next cocktail.
- If you want to prepare the boozy root beer floats ahead of time, scoop the vanilla ice cream into individual glasses and place them in the freezer. This way, they’re ready to go when you are.
- Avoid freezing the root beer and spiced rum together with the ice cream. The carbonation in the root beer can cause it to expand and potentially create a mess.
- If you have leftover assembled boozy root beer floats, it's best to enjoy them fresh. However, if you must store them, cover the glasses with plastic wrap and place them in the freezer. Be aware that the texture might change upon thawing.
- For the optional whipped cream, store it in the refrigerator in an airtight container. If it's homemade, it will last for about 2-3 days.
- Keep the maraschino cherries in their original jar, tightly sealed, and store them in the refrigerator. They can last for several months, ready to top off your next dessert or cocktail.
How to Reheat Leftovers
- First, separate the vanilla ice cream from the liquid components if possible. This will help maintain the integrity of the ice cream when reheating.
- Pour the root beer and spiced rum mixture into a saucepan. Heat gently over low heat until it reaches a warm but not boiling temperature. Stir occasionally to ensure even heating.
- While the liquid is warming, place the vanilla ice cream in a microwave-safe bowl. Microwave on low power in 10-second intervals until it softens slightly but doesn't melt completely.
- Once the liquid is warmed, pour it back over the softened vanilla ice cream in a glass.
- If you prefer a more integrated texture, you can blend the warmed liquid and softened vanilla ice cream together using a blender for a few seconds.
- Top with whipped cream and a maraschino cherry if desired, and enjoy your reheated boozy root beer float!
