This luxurious, velvety drink is just the thing to sip on a cool night — and using a slow cooker makes it especially easy to pull together. Heat the cream and butter first, slowly so that the mixture doesn't break. Then whisk in dark brown sugar, followed by spiced rum, salt, and a Moroccan spice mix. The end result is a richly flavored batch of drinks perfect for entertaining. You can either serve the Buttered Rum right away, or keep it in the slow cooker on WARM, covered, for a few hours.
