I fell in love with rum cream on our first trip to Jamaica. Unfortunately, Sangsters (the Jamaican brand) isn't sold in the US so after going online and trying many recipes, tweaking this, removing that, I found what is the closest in flavor to the Sangster's brand. It makes an excellent gift as most people aren't familiar with it.
Mix all ingredients in a blender and run on a low setting for a minute, just long enough to blend.
Refrigerate for an hour for flavors to blend. Serve over ice, in coffee, over ice cream, or in any way one would use Irish cream. It has the same texture but not the bite of whiskey. Keeps for 2 weeks in the fridge, I'm told. It never stays around long enough at our house!
