This boozy take on the drink of Harry Potter will give you a taste for life as if it were in J.K Rowling's world, but with an adult twist! The butterscotch syrup and cream soda are seasoned with spiced rum to make this alcoholic warm drink really stick its landing on your palate.
In a crock-pot, combine all ingredients except the rum and cook in slow heat for 3 or 3 and ½ hours.
Turn off the heat and stir in the rum.
Transfer to serving glasses and top with whipped cream.
You can remove the rum for a kid-friendly version of the drink. Also, if you want a more salty version, you can opt to use salted butter.
