In a large pot, combine all ingredients except dough. Slowly heat, stirring frequently, 10 to 12 minutes. Do not allow to come to a boil.
Meanwhile, sprinkle your work surface with a little flour. With a rolling pin, evenly roll out dough. Dip Halloween cookie cutters in flour and cut out shapes from the dough. Bake until light golden brown, about 7 to 10 minutes. Allow to cool and serve with soup.
