Hot Buttered Rum Slow Cooker Recipe

This is the ultimate guide to creating the perfect slow-cooked hot buttered rum. Imagine a slow cooker quietly bubbling away, filling your kitchen with the scent of butter, cinnamon, nutmeg, and brown sugar while you go about your evening. By the time you’re ready for a cup, you’ll have a smooth, spiced, and luxurious drink that feels like pure comfort in a mug.

Ingredient List

Here’s what you’ll need to make a batch of 6-8 servings:

• 1 cup unsalted butter – Softened for easier mixing; the butter is the heart of the drink.
• 1 cup packed brown sugar – Light or dark brown sugar works, depending on how rich and caramel-like you want it.
• 2 teaspoons ground cinnamon – Adds warmth and depth.
• 1 teaspoon ground nutmeg – Sweet, nutty, and aromatic.
• 1/2 teaspoon ground cloves – Optional but gives that classic holiday spice aroma.
• 1/2 teaspoon salt – Balances sweetness and enhances flavors.
• 4 cups water – The base for the slow cooker mixture; can substitute with apple cider for extra flavor.
• 2 cups dark rum – The star of the show; adjust according to taste and strength preference.
• Optional garnishes: Whipped cream, cinnamon sticks, or a sprinkle of nutmeg for serving.

Instruction Guide

Here’s how to turn these ingredients into a magical batch of hot buttered rum:

1. Prepare The Butter-sugar-spice Mix

   • In a medium bowl, cream together the softened butter and brown sugar.
   • Add the cinnamon, nutmeg, cloves (if using), and salt. Mix until smooth.
   • This is your “butter batter”, and it’s essentially the flavor engine of your drink.

2. Transfer To The Slow Cooker

   • Pour 4 cups of water into your slow cooker.
   • Drop in the butter-sugar-spice mixture.
   • Stir until it begins to dissolve slightly.

3. Slow-cook The Mixture

   • Cover and cook on low for 2-3 hours, stirring occasionally.
   • This gentle heat allows the butter and sugar to fully meld with the spices, creating a silky, aromatic base.

4. Add The Rum

   • Once the base is fully blended and aromatic, pour in the rum.
   • Stir gently and keep the slow cooker on warm until ready to serve.

5. Serve

   • Ladle into mugs and top with optional whipped cream, a sprinkle of nutmeg, or a cinnamon stick.
   • Sit back, sip slowly, and let the cozy vibes take over.

Ingredient Swaps

Sometimes, you might not have every ingredient on hand-or maybe you want to try a twist:

• Butter alternatives: Coconut oil or vegan butter works if you want a dairy-free version.
• Sugar options: Maple sugar or coconut sugar can add a slightly different flavor profile.
• Milk or cream addition: Replace part of the water with cream or milk for a richer, creamier texture.
• Spice variations: Cardamom, allspice, or ginger can create a unique seasonal flair.
• Alcohol swaps: Spiced rum, bourbon, or even brandy can be used instead of dark rum for different flavor notes.

Helpful Tips

To get the best hot buttered rum possible, here are some practical tips:

• Softened butter is key – If the butter is too hard, it won’t blend properly with the sugar.
• Taste as you go – The sweetness and spice levels are adjustable; don’t be afraid to tweak to your preference.
• Keep the slow cooker on warm – Avoid cooking too long after adding the rum, or the alcohol may evaporate.
• Stir occasionally – Even on low heat, stirring ensures the flavors combine evenly.
• Batch-making – This recipe doubles easily for parties, and the base can even be prepared ahead and frozen for later.

Customization Ideas

Make this hot buttered rum uniquely yours:

• Holiday twist: Add a few cranberries or a splash of orange zest to infuse a festive flavor.
• Coffee addition: Replace half of the water with brewed coffee for a caffeinated kick.
• Vanilla touch: A teaspoon of pure vanilla extract adds warmth and depth.
• Smoky version: Use a dark, smoky rum or add a tiny pinch of smoked sea salt for complexity.
• Chocolate indulgence: Stir in a spoonful of cocoa powder or chocolate syrup for a mocha-style drink.
