The Ultimate Boozy RumChata Root Beer Float

By Jason Griffith

There is something inherently nostalgic about a root beer float. It’s the quintessential American treat—fizzy, creamy, and undeniably satisfying. But as much as I love the classic version I had as a kid, my adult palate occasionally craves something with a bit more depth. Enter the RumChata Root Beer Float.

By swapping a bit of that childhood nostalgia for the smooth, cinnamon-spiced notes of RumChata, you transform a simple soda shop staple into a sophisticated dessert cocktail. It’s thick, it’s fizzy, and it’s become my absolute favorite way to cap off a backyard BBQ or a cozy night in.

Why I Love This Recipe

If you’ve followed my work here at ChefManiac, you know I’m a sucker for “dessert-inspired vibes.” In fact, this float reminds me a lot of The Slippery Drank, another one of my go-to sweet sippers.

What makes the RumChata version stand out is the RumChata itself. For the uninitiated, RumChata is a cream liqueur made with premium Caribbean rum, real dairy cream, cinnamon, and vanilla. When it hits the spicy, herbal notes of a high-quality root beer, magic happens. The creaminess of the liqueur mimics the melting ice cream, while the cinnamon adds a “warmth” that elevates the whole experience. Plus, it only takes three main ingredients and about two minutes to make.

Ingredients You’ll Need

To get that perfect ratio of fizz to cream, you’ll need:

• 2 oz RumChata: This is the star of the show. Keep your bottle chilled if possible!
• 1 cup Root Beer: Choose a high-quality, craft root beer for the best flavor profile. Make sure it is thoroughly chilled to prevent the ice cream from melting too fast.
• 2 scoops Vanilla Ice Cream: A classic, rich bean vanilla works best here.
• Whipped Cream (Optional): For that “pro-bartender” look.
• Maraschino Cherry: The classic finishing touch.

Swaps and Notes

• The Root Beer: If you want a deeper flavor, try a sarsaparilla. If you’re watching calories, a diet root beer works surprisingly well here because the RumChata provides plenty of richness.
• The Ice Cream: While vanilla is king, cinnamon or salted caramel ice cream can take this to a whole new level of decadence.
• Dairy-Free Option: You can use a dairy-free vanilla bean frozen dessert and a splash of spiced rum with coconut milk if you are avoiding dairy, though the authentic RumChata does contain real cream.

Step-by-Step Instructions

1. Prep the Glass: For the best experience, place a tall glass or a beer mug in the freezer for 10 minutes before starting. A frosted glass keeps the float colder for longer.
2. Scoop the Ice Cream: Add 2 generous scoops of vanilla ice cream to your chilled glass.
3. The RumChata Pour: Slowly pour the 2 oz of RumChata directly over the ice cream. This allows the liqueur to coat the scoops, creating a creamy barrier.
4. Add the Fizz: Gently pour in the chilled root beer. Tilt the glass slightly as you pour—just like pouring a beer—to control the head of foam. RumChata can sometimes cause root beer to foam up more than usual, so go slow!
5. Garnish and Serve: Top with a swirl of whipped cream and a cherry. Drop in a straw and serve immediately.

Tips for Success

• Avoid the “Curdle”: Because RumChata contains dairy and root beer is acidic, there is a slight chance of separation if the root beer is warm. Always use ice-cold root beer to keep the mixture smooth and incorporated.
• The Order Matters: Always put the ice cream in first. If you pour the liquids first and then drop the ice cream in, you’ll end up with a “soda volcano” all over your counter.
• Don’t Stir Too Much: Let the natural melting process combine the flavors. If you stir too vigorously, you’ll lose all the carbonation.

Serving Suggestions and Pairings

This boozy float is the ultimate party closer. If you’re hosting a game day or a casual get-together, I love serving these alongside salty, savory appetizers to balance the sweetness.

Start your party with a savory spread like this beer cheese dip or a big tray of these totchos. The saltiness of the tater tot nachos provides the perfect foil for the creamy, spiced sweetness of the float.

Storage and Leftover Tips

As with any carbonated beverage or frozen treat, this does not store well. Once the root beer is poured and the ice cream is scooped, it’s a “drink it or lose it” situation! If you find yourself with leftover RumChata, simply keep it in a cool, dark place (it does not require refrigeration after opening, though I prefer mine cold).
