Ingredients You’ll Need

You don’t need a bar cart full of spirits—just a few quality ingredients that really shine:

• Dark Rum: Brings deep, caramel and molasses notes that complement the root beer beautifully. Choose a spiced or aged rum for even more flavor.
• Root Beer: Use your favorite brand! The better the root beer, the better the cocktail. Go for one with real sugar and strong vanilla notes if possible.
• Heavy Cream or Half-and-Half: Adds a rich, smooth texture that transforms the drink into something indulgent and silky.
• Vanilla Extract (Optional): Just a drop can enhance the creaminess and echo the vanilla already in the root beer.
• Ice: Keeps things chilled and refreshing without watering the drink down too fast.
• Whipped Cream (Optional Garnish): Adds a dessert-like touch—totally optional but totally worth it.

• Frozen Version: Blend everything with ice for a root beer rum milkshake vibe.

• Add Ice Cream: Scoop in some vanilla ice cream to make it more like a float—ideal for dessert cocktails.
• Cinnamon Spice: Add a pinch of cinnamon or use spiced rum for a warm twist.
• Different Soda: Swap root beer for cream soda or cola for a new flavor profile.

How to Make Creamy Root Beer Rum Cocktail

This cocktail is as easy as it gets. No shaker, no muddling—just build it right in the glass!

Step 1: Fill the Glass with Ice

Use a tall glass and fill it with ice cubes to keep everything chilled and refreshing.

Step 2: Pour in the Rum

Add your dark rum over the ice. Use more or less depending on how strong you like your drinks.

Step 3: Add the Root Beer

Slowly pour the root beer into the glass. It’ll fizz a bit—let it settle if needed before the next step.

Step 4: Stir in the Cream

Pour the heavy cream or half-and-half over the top, then gently stir to combine. You’ll see a beautiful swirl that makes this drink as lovely to look at as it is to sip.

Step 5: Garnish (Optional)

Top with whipped cream and a sprinkle of nutmeg or cinnamon if you’re feeling fancy. Add a paper straw or cocktail cherry for fun.

Pro Tips for Making the Recipe

• Chill Your Ingredients: Cold root beer and rum will keep the ice from melting too quickly, keeping the drink smooth.
• Layering Looks Beautiful: Pour the cream slowly for a layered effect before stirring.
• Don’t Over-Stir: Mix just enough to blend the cream, but keep that velvety texture.
• Pick the Right Glass: A highball or large rocks glass gives plenty of room for fizz and cream.

How to Serve

This cocktail shines brightest when served immediately. It’s ideal as:

A Dessert Drink

Perfect for rounding out a dinner party or date night with something sweet and sippable.

Party Treat

Serve in mason jars with fun straws for a casual backyard gathering.

Movie Night Pairing

Goes surprisingly well with salty snacks like popcorn or pretzels.

Tip: Want to make a big batch? Mix the rum and root beer ahead of time in a pitcher, then add cream to each glass before serving.

Make Ahead and Storage

Storing Leftovers

Because of the dairy and carbonation, this cocktail doesn’t store well after mixing. It’s best made fresh.

Freezing

Not recommended. The carbonation and cream won’t hold up in the freezer.

Reheating

No need—this is a cold cocktail! Just remake it if needed. It’s quick enough that you won’t mind.

FAQs

Can I use light rum instead of dark rum?
You can, but you’ll miss out on some of the depth and molasses richness that dark rum brings. If light rum is all you have, consider adding a touch of brown sugar or maple syrup to mimic that flavor.

What kind of root beer works best?
Go for a craft or high-quality root beer with real cane sugar and natural flavors. Brands like IBC, Barq’s, or A&W work well, but feel free to experiment.

Is there a dairy-free option?
Absolutely! Swap the cream for a splash of full-fat coconut milk or a barista-style oat milk for a creamy texture without the dairy.

Can I batch this for a party?
Yes! Mix the rum and root beer ahead in a pitcher and chill. Pour into individual glasses over ice, then top each with cream just before serving for the best results.
