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:
- Line an 8x8 inch baking pan with parchment paper or foil, leaving an overhang on two sides for easy removal.
- In a heavy-bottomed saucepan, combine the granulated sugar, milk, butter, and salt.
- Cook over medium heat, stirring constantly, until the sugar dissolves and the mixture comes to a rolling boil.
- 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.
- Take the saucepan off the heat.
- Immediately add the chocolate chips and stir until melted and smooth.
- Quickly stir in the marshmallow fluff and vanilla extract until just combined. Be careful not to overmix.
- Pour the fudge mixture into the prepared pan and spread evenly.
- Refrigerate for at least 2 hours, or until firm.
- Once firm, lift the fudge out of the pan using the parchment paper overhang. Cut into 16 squares and serve.
