UPDATE: For those of you who think there is too much butter, you really MUST stir it well before serving into each cup, then add the rum and top with whipping cream and freshly ground nutmeg. There is nothing better! The butter really gives it its rich taste. One more thing, use dark rum. Made this for a party I had on Christmas Eve. Everyone raved. I doubled the recipe and added the rum to cups before topping it with this. The whipping cream and freshly ground nutmeg really made it. I think this has become a new traditional winter drink for us.

Very yummy! Perfect after a delicious dinner with friends.

For those of you that have complained about the recipe, let me give you some advice. At no time should there be any butter floating as a glob that you have to "mop" up. You don't have your crock pot hot enough. Start it out on high if you plan on having this drink in a couple of hours. I let it usually simmer for 4-5 hrs and it is an after dinner drink. When the crock is steaming and the buter is glistening, then you have your batch correct. Don't add the rum to the pot if it is too much. Add it to the each mug to taste. If you alter this recipe with splenda or margarine and still rate this poorly, that is your problem. Best of luck to those who take another stab at it. I think you will be happier with the results...
