Cream together the sugars and the butter (I use my KitchenAid mixer for this part) until creamy.
Add spices and pumpkin butter until well combined.
Put magical mixture in a glass bowl or jar and put in the fridge until almost firm.
In your favorite mug add:
2 tbsp (or more, if you have a big mug) of the mix
3oz Sailor Jerry's spiced rum (or more, if you're a big lush — I mean, have a big mug)
Then top with boiling water, stir WELL until completely mixed, and add a dollop of fresh whipped cream and maybe add sprinkles or a drizzle of maple syrup.
