Buttered rum eggnog is a rich and creamy holiday drink that brings together the sweetness of eggnog with the warm, comforting flavor of buttered rum. With its smooth texture and a hint of spice, it’s the perfect treat to cozy up with on a chilly evening. This drink feels like a hug in a glass, balancing the creamy dairy with a little kick that makes it special.
I love making buttered rum eggnog when friends come over because it’s easy to sip and always gets everyone in a festive mood. Adding a sprinkle of cinnamon or nutmeg on top gives it that extra touch of warmth I enjoy. If you’re like me, you’ll find it hard to stop after just one glass!
My favorite way to serve this eggnog is in a festive mug or glass, garnished with a cinnamon stick for stirring. It’s the kind of drink that makes holiday gatherings feel extra cozy and cheerful, perfect for sharing stories and laughter. If you haven’t tried buttered rum eggnog yet, it’s definitely worth making a special night even better.
Key Ingredients & Substitutions
Eggs: They give eggnog its classic creamy texture. Using fresh eggs is best. If you prefer to avoid raw eggs, you can use pasteurized eggs or cook the mixture gently while whisking.
Butter & Brown Sugar: These create the buttery, caramel-like flavor in the rum mix. Unsalted butter keeps the taste balanced. For a dairy-free option, try coconut oil, though the flavor will change.
Rum: Dark rum adds warmth and depth. Spiced rum is also great if you want more holiday spice. For a non-alcoholic version, use rum extract or vanilla extract instead.
Milk & Heavy Cream: Whole milk and cream make the eggnog rich and smooth. You can substitute with almond milk or oat milk for a lighter or dairy-free option, but the texture may differ.
Spices: Cinnamon and nutmeg are essential for that festive flavor. Freshly grated nutmeg tastes best. You can add a pinch of cloves or allspice for a twist.
How Can I Safely Use Raw Eggs in Eggnog?
Raw eggs add richness but can worry some people. Here’s how to make it safer and tasty:
- Use pasteurized eggs if possible; they’re heated gently to kill bacteria but stay raw.
- If pasteurized aren’t available, you can gently heat your egg yolks with sugar and milk mixture in a saucepan over low heat, stirring constantly, until it reaches 160°F (71°C). This heats the eggs enough to be safe without cooking them.
- Whip the egg whites separately and fold them in for a fluffy texture.
- Keep the eggnog refrigerated and consume within 1-2 days.
Taking these steps keeps the eggnog safe while keeping that smooth, rich mouthfeel that makes this drink special.
Equipment You’ll Need
- Small saucepan – I prefer it because it helps melt the butter and spices evenly without burning.
- Mixing bowls – You’ll need one for whisking egg yolks and one for beating egg whites, making prep easier.
- Whisk or hand mixer – A whisk is great for gentle mixing; a mixer can speed up beating the egg whites.
- Measuring cups and spoons – Precise measurements help get the perfect balance of flavors.
- Fine mesh strainer (optional) – If you want extra smooth eggnog, strain it before serving.
- Glass mugs or glasses – For serving, I like festive mugs that make it feel special.
Flavor Variations & Add-Ins
- Use spiced rum or add a dash of ginger for more holiday warmth.
- Top with whipped cream and a sprinkle of cinnamon or nutmeg for extra richness.
- Try vanilla or caramel liqueur instead of rum for a different flavor twist.
- Add a splash of orange liqueur, like Grand Marnier, for citrusy brightness.

This recipe takes about 15 minutes to prepare and mix, plus at least 1 hour chilling time in the refrigerator. Chilling helps the flavors blend perfectly for that rich and smooth holiday drink.
Step-by-Step Instructions:
1. Make the Buttered Rum Mixture:
In a small saucepan over low heat, combine the softened butter, brown sugar, ground cinnamon, and nutmeg. Stir constantly until the butter melts and everything is smooth and fragrant, about 3 to 5 minutes. Remove from heat and let it cool down a bit.
2. Mix Egg Yolks and Sugar:
In a large bowl, whisk together the egg yolks and half of the granulated sugar (about 1/6 cup) until the mixture thickens and turns pale yellow. This will take a few minutes.
3. Add Milk, Cream, Vanilla, and Buttered Rum:
Slowly whisk in the milk, heavy cream, vanilla extract, and the cooled buttered rum mixture until everything is well combined.
4. Stir in the Rum:
Add the dark rum and give it a good stir.
5. Whip Egg Whites:
In a clean bowl, beat the egg whites with a pinch of salt until soft peaks form. Gradually add the remaining sugar and continue beating until stiff peaks form.
6. Combine Whipped Egg Whites and Eggnog Mix:
Gently fold the fluffy egg whites into the eggnog mixture until smooth and creamy. This adds a light, airy texture.
7. Chill and Serve:
Cover and refrigerate the eggnog for at least 1 hour to let the flavors meld. When ready to enjoy, pour into glasses, sprinkle freshly grated nutmeg on top, and add a cinnamon stick if you like.
8. Cheers!

Can I Use Frozen Eggs for This Eggnog?

Yes! You can prepare the eggnog up to 24 hours in advance. Just keep it well covered in the fridge and give it a good stir before serving. This actually helps the flavors meld beautifully.
How Should I Store Leftover Eggnog?
Store any leftovers in an airtight container in the refrigerator for up to 2 days. Shake or stir gently before serving again, as separation may occur.
