Fantasy Fudge for two

In a double boiler or a glass bowl over a pan of simmering water, melt the chocolate chips and condensed milk. Stir occasionally. Meanwhile, add the marshmallow creme to a large bowl on a scale. (Trust me, the neatest way to do this is to use a scale and scoop the creme directly into the bowl you will be mixing the other ingredients in.) When the chocolate is melted, pour it over the marshmallow creme. Fold the mixture together until no white streaks remain. Add the vanilla and blend well. Stir in the pecans or save them for the top, your choice. Scrape the mixture into a loaf pan. Chill the pan in the fridge for several hours, then let it come to room temperature before slicing and serving.
