  • 1 teaspoon vanilla extract

Equipment

  • 9x13 inch baking pan
  • parchment paper
  • large saucepan
  • wooden spoon or heatproof spatula

Method
 

Preparation
  1. Line a 9x13 inch pan with parchment paper, leaving an overhang on the sides for easy removal.
  2. Combine sugar and milk in a large saucepan over medium heat, stirring until the sugar dissolves.
Cooking
  1. Bring the mixture to a rolling boil and continue boiling for 5 minutes without stirring.
  2. Remove the saucepan from heat and quickly stir in peanut butter, marshmallow fluff, butter, and vanilla extract until completely smooth and combined.
Finishing
  1. Pour the hot fudge into the prepared pan, spreading it evenly.
  2. Allow the fudge to cool completely at room temperature or in the refrigerator until firm, then cut into squares and serve.

Notes

For best results, use a heavy-bottomed saucepan to prevent scorching. Do not stir the mixture once it begins to boil to ensure proper crystallization and texture.
