Grandma's Peanut Butter Fudge

Butter a 9x13 inch baking dish and set aside. Butter a 3 quart saucepan.

Place buttered saucepan over medium heat and combine sugar evaporated milk and 1 cup butter within. Heat to between 234 and 240 degrees F (112 to 116 degrees C) or until a small amount of syrup dropped into cold water forms a soft ball that flattens when removed from the water and placed on a flat surface.

Remove from heat and stir in peanut butter and marshmallow creme. Beat vigorously until smooth. Pour quickly into prepared baking dish. Let cool completely before cutting into squares.
