The buttered rum cocktail, as the name implies, is made with a lot of spiced butter and rum. Like a spiced cookie right out of the oven, the warm cocktail is sweetened with brown sugar and orange juice. Rich and decadent, this sinful drink is sure to keep you warm during the cold Winter months. For all of your holiday parties, make a large batch in a crockpot and let guests serve themselves. Watch the video to see how it's whipped up.
