1. In a large mixing bowl, mix together sugar free vanilla pudding mix, nonfat milk, half and half, sweetener, ground cinnamon, dash of nutmeg , and rum extract.
2. Mix these very well with a wire whisk for at least 2 minutes. If this is too thick, add more milk if you like it thinner and more sweetener if you want it sweeter. Chill for 1 hours. Serve, of course, with a grating of fresh nutmeg dusted over each icy, creamy mug of holiday heaven.
