Cook VERY slowly (bring to a boil, then turn down heat, never let it boil fast) in heavy saucepan for AT LEAST 2 hours uncovered, stirring once in a while, until mixture forms a firm ball in cold water.

When done, add 1 jar of marshmallow cream and 1 cup Peanut Butter.

Beat Until Well Mixed Then Pour In Buttered 8X10 Pan.
