There’s something about a warm, buttery cocktail on a chilly evening that feels like the ultimate little luxury. This hot buttered rum is rich, sweet, warming and full of cozy spices, with a subtle hint of fresh Sumo Citrus that makes it feel a little extra special.
The secret is the homemade spiced butter batter. Softened butter and brown sugar are whipped together with cinnamon, nutmeg, cloves, vanilla and fresh citrus zest to create a fragrant mixture you can keep in the fridge and use whenever the mood strikes. Add a spoonful to a mug with dark rum and boiling water, give it a good stir, and you’ve got yourself a wonderfully comforting winter cocktail.
I love that the citrus doesn’t overpower the classic flavors. Instead, the zest brings a fresh, fragrant note to the buttery spice mixture, while a tiny splash of juice adds just a little brightness. It’s a small twist that makes this version feel special without taking away from what makes hot buttered rum so delicious in the first place.
Even better, the batter makes enough for around 10–12 drinks, so you can prepare it ahead of time for holiday gatherings, a cozy night in, or whenever you want a warming cocktail without starting from scratch.
●Classic and cozy: Dark rum, brown sugar, butter and warming spices make this the kind of cocktail you’ll want to sip slowly on a cold evening.
●A subtle citrus twist: Fresh Sumo Citrus zest adds a fragrant, aromatic note that complements the cinnamon, nutmeg and cloves beautifully.
●Make-ahead friendly: Prepare the butter batter in just a few minutes, then keep it refrigerated so your next cocktail is only a few steps away.
●Simple ingredients: You don’t need fancy cocktail equipment or complicated syrups. A bowl, a mug and a spoon will do the job.
●Perfect for entertaining: Make a batch of batter before guests arrive and let everyone enjoy a freshly mixed hot buttered rum.
Hot buttered rum is a classic warm cocktail made with rum, hot water and a sweetened butter mixture flavored with spices. The butter batter melts into the hot liquid, creating a rich, comforting drink with a lovely buttery finish.
Unlike a chilled cocktail, this one is all about warmth and aroma. Dark rum brings notes of caramel, vanilla and molasses, while brown sugar adds sweetness and the spices give it that familiar winter feel.
My version keeps all those classic flavors but adds Sumo Citrus zest to the butter batter for a fresh, fragrant twist. It’s subtle rather than sharply citrusy, so the drink still tastes unmistakably like hot buttered rum.
●Unsalted butter: Softened butter is essential for creating a smooth, creamy batter that mixes easily with the sugar and spices.
●Light brown sugar: Adds sweetness and a warm caramel flavor that pairs beautifully with dark rum.
●Sumo Citrus zest: Just a teaspoon adds a lovely fragrance without making the batter taste overly citrusy.
●Ground cinnamon: Gives the batter its familiar warming spice.
●Ground nutmeg: Adds a slightly sweet, earthy flavor that works especially well in warm drinks.
●Ground cloves: A small amount brings depth and a classic holiday aroma.
●Vanilla extract: Rounds out the flavors and adds a little extra warmth.
●Salt: A small pinch balances the sweetness and brings all the flavors together.
●Dark rum: Choose a dark rum with rich, caramel-like notes. It stands up beautifully to the buttery, spiced batter.
●Spiced butter batter: One heaping tablespoon is enough to create a rich, flavorful drink
●Boiling water: Hot water melts the batter and brings everything together into a smooth, fragrant cocktail.
●Sumo Citrus juice: Optional, but adds a levely floral sweetness
●Cinnamon stick: Another optional garnish that looks lovely and adds a little extra spice as you sip.
The batter is the part that takes a few minutes of preparation, but it’s well worth making a batch. Once it’s ready, you can store it in the fridge and use it to make individual cocktails whenever you like.
1.Beat the butter and sugar. Add the softened butter and packed light brown sugar to a mixing bowl. Beat until smooth and creamy, scraping down the sides of the bowl as needed.
2.Add the spices and citrus. Mix in the Sumo Citrus zest, cinnamon, nutmeg, cloves, vanilla extract and salt. Continue mixing until everything is evenly incorporated and the batter is fragrant.
3.Store until needed. Transfer the batter to a clean, airtight container and refrigerate for up to 3 weeks, as long as it’s kept properly chilled and handled with clean utensils.
That’s it! Your spiced butter batter is ready to use whenever you’re craving a cozy cocktail.
Once you’ve made the batter, the drink itself couldn’t be easier.
1.Add the batter to a mug. Spoon one heaping tablespoon of the spiced Sumo Citrus butter batter into a heatproof mug.
2.Pour in the rumand citrus juice Add 1½ -2 ounces of dark rum and 1 oz of sumo citrus or mandarin juice.
3.Add the hot water. Carefully pour in 4–5 ounces of boiling water. Stir thoroughly until the butter has melted and the drink looks glossy and fragrant.
4.Garnish and serve. Add a cinnamon stick, if desired. Serve hot and enjoy!
My tip: Give the drink a really good stir before serving. The goal is to incorporate the melted butter into the rum and water rather than leaving a thick layer of butter floating on top.
If you’ve never tried hot buttered rum, imagine the cozy flavors of brown sugar, cinnamon, nutmeg and vanilla, combined with the rich caramel notes of dark rum. The butter gives the drink a silky, rounded mouthfeel, while the hot water makes it wonderfully warming.
The Sumo Citrus is a subtle finishing touch. Its zest adds a bright, fragrant aroma that balances the sweetness and spice without turning the drink into a citrus-forward cocktail. It’s still rich and buttery, just with a little extra freshness.
It’s the kind of drink that’s made for slow sipping, whether you’re curled up on the couch or serving mugs to friends during the holiday season.
●Start with softened butter. If the butter is too cold, it won’t blend smoothly with the sugar. Let it soften at room temperature before mixing.
●Beat the batter until creamy. A smooth batter is easier to spoon into your mug and helps the ingredients combine evenly.
●Use a good dark rum. You don’t need the most expensive bottle, but choose one you enjoy drinking. Its flavor is a big part of the finished cocktail.
●Adjust the water to taste. Start with 4 ounces for a richer drink, or use 5 ounces if you prefer it a little lighter.
●Stir thoroughly. Butter needs a little encouragement to blend with the hot water and rum. Stir until the mixture is fully melted and incorporated.
●Don’t skip the zest. The amount is small, but it gives the batter a lovely fragrance. If you’re making this for someone who prefers a more traditional flavor, you can leave the citrus out.
Absolutely! The citrus is a little twist on the classic recipe, not an essential ingredient. Simply leave out the Sumo Citrus zest and juice if you’d prefer a more traditional spiced butter batter. The drink will still be delicious.
Yes. If Sumo Citrus isn’t available, use the finely grated zest of another sweet orange. Keep the quantity the same so the citrus doesn’t overpower the spices.
Dark rum is my first choice because its richer flavor works so well with the butter and brown sugar. However, you can use another rum you enjoy. Just keep in mind that a lighter rum may produce a less robust flavor.
You can use a slightly smaller spoonful of batter or add a little more hot water to suit your taste. The batter itself is designed to be sweet, so adjusting the amount in each mug is the easiest way to customize your drink.
One of the best things about this hot buttered rum recipe is that you can prepare the batter well before you need it.
●Refrigerator: Store the spiced butter batter in a clean, airtight container in the refrigerator for up to 3 weeks. Always use a clean spoon when scooping it out.
●Before serving: If the batter has become firm in the fridge, let the portion you’re using soften slightly so it’s easier to measure and incorporate.
●For entertaining: Make the batter a day ahead if you can. It gives you one less thing to prepare when you’re hosting, and all you need to do is add rum and hot water when it’s time to serve.
I recommend making the cocktail fresh in each mug rather than mixing the entire batch in advance. That way, everyone can enjoy it hot.
Use one heaping tablespoon of batter for each cocktail, along with 1½ ounces of dark rum and 4–5 ounces of boiling water.
This recipe makes enough batter for approximately 10–12 drinks, depending on how generously you scoop each tablespoon.
Yes! The batter is ideal for preparing ahead. Store it in an airtight container in the refrigerator for up to 3 weeks.
No. Sumo Citrus adds a lovely fragrance and a subtle fresh note, but you can substitute another sweet orange or leave the citrus out entirely.
You can reduce the amount of rum or add a little more hot water to make a lighter drink. Adjust the proportions to suit your taste.
Definitely. Prepare the butter batter in advance and set out the rum, hot water and mugs when you’re ready to serve. Each drink can be assembled individually in just a couple of minutes.
Serve hot buttered rum in a heatproof mug with a cinnamon stick and a little curl of citrus peel. I love keeping the garnish simple so the warm, golden-brown color of the drink can shine.
It’s lovely for a chilly evening at home, a holiday get-together, or a festive dinner party when you want to serve something a little different from the usual chilled cocktails. You could even package the butter batter in a small airtight jar as part of a seasonal hosting gift, with instructions for mixing a drink.
However you serve it, the best part is that you can make the batter ahead and enjoy a cozy cocktail whenever the occasion calls for it.
This hot buttered rum is proof that a classic doesn’t need much changing to feel special. Rich butter, brown sugar, dark rum and warming spices do most of the work, while a little Sumo Citrus zest adds a fragrant twist that makes every sip feel extra cozy.
Make the batter ahead, keep it in the fridge, and you’ll be ready for those chilly evenings when you want something warm, comforting and just a little indulgent. Cheers!
