Butter Rum Sauce is a buttery caramel-like-sauce that has a lovely flavor from the dark rum. Don’t worry it doesn’t taste like a cocktail as the liquor will boil out during cooking. It is made with 5 simple ingredients – butter, brown sugar, sugar, cream, and dark rum.
It is perfect drizzled over apple spice cake, apple crostata, brownies, apple nachos, bread pudding, pancakes or just ice cream! And if I’m being honest I have been spotted eating it by the spoonful (it’s REALLY good!).
Ingredients & Supplies
You don’t need much to make this butter rum sauce recipe, just 5 ingredients:
- saucepan
- 1 stick of butter (preferably salted)
- brown sugar
- granulated sugar
- heavy whipping cream
- dark rum
Dark Rum
When you buy dark rum (or look through your liquor cabinet), you want to make sure you get “dark rum”. It will literally be darker in color, like a caramel color. Definitely do not use the clear rum, it will not have the right flavors for this recipe. Dark rum is aged and the molasses flavors are enhanced.
If dark rum is not something you would normally keep in the house or would use for cocktails, you can absolutely buy an airplane sized bottle of dark rum! They are usually kept up by the registers at the liquor store.
Rum Extract
If you prefer to not use alcohol you can absolutely sub 1 teaspoon rum extract for the dark rum.
How to Make Butter Rum Sauce
There is not much to making this Butter Rum Sauce. Just add all the ingredients to a saucepan over medium heat. Let it all melt together and then let it simmer for about 2-3 minutes.

Remove it from the heat and let it cool. It will thicken more as it cools.
If you like a stronger rum/alcohol flavor you can wait and add the rum in the last 30 second of simmering the sauce. But, be careful that it doesn’t boil up on you!
Storing
Store your cooled butter rum sauce in the fridge in an airtight container for up to 2 weeks. I like to store mine in a mason jar with a lid.
Reheating
To reheat the sauce just portion out how much you want to use into a saucepan and place over low heat for about 5 minutes (less if you only have 1 or two portions), stirring occasionally, until it is the right consistency for drizzling!
