Straight from the Fluff website, can't screw up this fudge recipe!

• Ready In: 12 mins
• Serves: 49
• Yields: 49 1" square pieces

Ingredients

• 2 1⁄2 cups sugar
• 1⁄4 cup butter or 1⁄4 cup margarine
• 1 (5 1/3ounce) can evaporated milk
• 1 (7 1/2ounce) jar marshmallow cream
• 3⁄4 teaspoon salt
• 9  ounces peanut butter

Directions

1. Grease a 9 inch square pan & set it aside. (I use an 8x8 tin & don't grease & it works fine).
2. In a large sauce pan combine the first 5 ingredients. Stir over low heat until blended.
3. Over medium heat, bring to a full rolling boil being careful not to mistake escaping air bubbles for boiling. Boil slowly, stirring constantly for 5 minutes. (once it starts to boil I turn the timer on for 5 minutes & turn the heat to about 6 or 7 on the burner.).
4. Remove from heat, stir in peanut butter untill blended.
5. Turn into greased pan & cool.
