Ingredients:

  • 2 cups (400g) granulated sugar
  • 1 cup (240ml) whole milk
  • ½ cup (115g) unsalted butter, cut into cubes
  • ¼ teaspoon salt
  • 12 ounces (340g) semi-sweet chocolate chips
  • 7 ounces (200g) marshmallow fluff (about 1 jar)
  • 1 teaspoon vanilla extract

Instructions:

  1. Line an 8x8 inch baking pan with parchment paper or foil, leaving an overhang on two sides for easy removal.
  2. In a heavy-bottomed saucepan, combine the granulated sugar, milk, butter, and salt.
  3. Cook over medium heat, stirring constantly, until the sugar dissolves and the mixture comes to a rolling boil.
  4. Attach a candy thermometer to the side of the pan. Continue cooking, stirring occasionally, until the mixture reaches 235°F (113°C) – soft-ball stage.
  5. Take the saucepan off the heat.
  6. Immediately add the chocolate chips and stir until melted and smooth.
  7. Quickly stir in the marshmallow fluff and vanilla extract until just combined. Be careful not to overmix.
  8. Pour the fudge mixture into the prepared pan and spread evenly.
  9. Refrigerate for at least 2 hours, or until firm.
  10. Once firm, lift the fudge out of the pan using the parchment paper overhang. Cut into 16 squares and serve.
