In a medium-sized bowl, combine the butter, brown sugar, cinnamon, nutmeg, cloves, vanilla extract, and salt.
Beat the mixture until smooth and creamy. Make sure that all the spices are well incorporated.
Add the softened vegan ice cream and whisk until fully combined.
Transfer the butter base to an airtight container and store in the freezer for up to a month. The recipe makes about 12 servings.

Top with vegan whipped cream and garnish with a sprinkle of cinnamon or nutmeg, and a cinnamon stick if desired.
Notes
Refrigerator: If you have an unfinished mug of hot buttered rum, you can refrigerate it for up to a day in an airtight container or covered in the original mug. Reheat in the microwave before enjoying.
Freezer: The butter base can be stored in the freezer for up to a month. For easy cocktails in the future, you can freeze it into 1-tablespoon portions in an ice cube tray, then you’ll know you need exactly 2 cubes to make a mug of this hot buttered rum recipe.
