Bourbon Root Beer Float Recipe (The Perfect Summer Cocktail!)

This is a perfect dessert-like cocktail and I never met a bourbon, or ice cream for that matter, that I didn’t like. Booze and ice cream are always perfect together. Comfort at its finest! After I scooped the ice cream into my mug, I poured the bourbon and the root beer over top. Then I decided that there wasn’t enough pizzaz so I added the drizzle of hot fudge. I did this with a little sandwich bag. I scooped the hot fudge in the bag with a spoon and snipped the corner off. Then I just applied pressure and squeezed the hot fudge over the bourbon root beer float. I even added a cherry… Can you blame me? And then of course, I blew bubbles with a straw. We all still have a little kid inside of us, right?

Why Bourbon Makes Everything Better (Trust Me!)

Bourbon brings a sophisticated warmth to this float that plain root beer just can’t achieve on its own. The vanilla and caramel notes in bourbon actually complement the spiced vanilla flavors of root beer beautifully, creating a more complex dessert drink than you’d expect. A good mid-range bourbon works perfectly here—you don’t need anything top-shelf, but you also want something you’d actually enjoy drinking straight. The alcohol content mellows slightly when mixed with cold ice cream and root beer, so you get the flavor benefit without an overwhelming kick. It’s comfort food meets grown-up indulgence, and honestly, once you try it this way, regular root beer floats start to feel a little plain by comparison.

The Best Root Beer for Cocktails

Not all root beers are created equal when you’re mixing them into cocktails—some are too sweet, others too syrupy, and many just disappear into the background. You’ll want a root beer with bold, complex spice notes that can hold its own against the bourbon without turning your drink into liquid candy. Brands like Barq’s have that slightly spicier edge, while craft options like Virgil’s or Stewart’s give you more authentic sassafras flavor that doesn’t get totally overpowered by the alcohol. The key is tasting a few options straight before you commit to a bottle—the one you love on its own will be the one that makes your float genuinely delicious rather than cloyingly sweet.

Ice Cream vs. Gelato: What Works Best

For a bourbon root beer float, regular vanilla ice cream is your best bet because it melts slightly faster and creates that creamy, drinkable consistency as the bourbon and root beer warm it up. Gelato, while luxurious, is denser and won’t blend as smoothly with the liquid components—you’ll end up with chunks rather than a cohesive float. The higher fat content in gelato also overpowers the delicate bourbon and root beer flavors, whereas classic ice cream acts as a neutral canvas that lets those tastes shine. Stick with good-quality vanilla ice cream, and you’ll get that perfect balance of scoops you can actually sip through a straw without fighting for every spoonful.

Bourbon Alternatives That Still Taste Amazing

If you’re not a bourbon drinker or want to switch things up, rye whiskey brings a spicier kick that pairs beautifully with root beer’s vanilla and sassafras notes. For something smoother, try Irish whiskey, which adds a subtle sweetness without overpowering the float. You could even experiment with whiskey blends or go in a completely different direction with spiced rum, which echoes the warm spice profile of root beer itself. The key is choosing something with enough character to stand up to the ice cream and root beer without getting lost in the mix—skip the cheap stuff and stick with mid-range spirits that actually taste good on their own.

Make It a Crowd-Pleaser: Serving Tips

This bourbon root beer float is surprisingly easy to scale up for a party—just set out a bourbon bottle, quality root beer, and soft ice cream so guests can build their own. The beauty of this drink is that non-drinkers can skip the bourbon entirely and still have an amazing dessert, making it inclusive for mixed groups. Keep your ice cream slightly softened (about 5-10 minutes out of the freezer) so it scoops easily and creates that perfect melty-around-the-edges texture when the cold root beer hits it. If you’re serving multiple floats, prep a hot fudge drizzle station with a squeeze bottle for that extra indulgence—it’s the kind of detail that makes people feel special without requiring much effort from you.

Storage Tips for Your Root Beer Float Bar

The best part about setting up a root beer float bar is that most components actually store beautifully for weeks. Keep your bourbon in a cool, dark cabinet away from direct sunlight, and your root beer will stay fresh in the fridge or pantry (check the expiration date on the bottle). Ice cream should obviously stay frozen, but here’s the pro tip: keep a few different flavors on hand so guests can mix and match—vanilla is classic, but don’t sleep on salted caramel or cookie dough. Store your hot fudge sauce in an airtight container at room temperature or in the fridge, and it’ll be ready to drizzle whenever the craving hits. Just make sure you have plenty of clean mugs, spoons, and straws on hand so everything feels effortless when your guests arrive.

Other Summer Cocktail Float Recipes

If you love this bourbon root beer float, you’ve got to try swapping in different spirits and flavors for your next gathering. Whiskey pairs beautifully with ginger ale and vanilla ice cream, while rum and cola is a classic combination that never disappoints. Don’t sleep on brandy with cream soda either—it’s sophisticated and surprisingly delicious. The beauty of float cocktails is that once you master the basic technique, you can experiment endlessly with whatever bourbon, liqueur, or spirit you have on hand mixed with your favorite soda and ice cream flavor.

Frequently Asked Questions About Bourbon Floats

The most common question I get is whether the bourbon will curdle the ice cream—spoiler alert, it won’t! The alcohol content is too low to affect the ice cream, and you’re essentially making a boozy milkshake as it melts. Another thing people ask is whether to use premium bourbon or something more budget-friendly, and honestly, a mid-range bourbon works beautifully here since the root beer and ice cream flavors are doing most of the heavy lifting. If you’re wondering about the ratio, I typically use 2 ounces of bourbon to a 12-ounce bottle of root beer, but feel free to adjust based on how strong you like your drinks. And yes, the hot fudge drizzle is totally optional—but why would you skip it?
