Ingredients:

  • 3 cups (510g) semi-sweet chocolate chips
  • 14 oz (397g) sweetened condensed milk
  • 1/4 cup (56g) unsalted butter, cut into small cubes
  • 1 tsp (5ml) pure vanilla extract
  • 1/4 tsp (1.5g) fine sea salt

Instructions:

  1. Line an 8x8 inch square baking pan with parchment paper, leaving an overhang on the sides for easy removal.
  2. In a large microwave-safe glass bowl, combine the semi-sweet chocolate chips, sweetened condensed milk, and cubed unsalted butter.
  3. Microwave the mixture on high for 1 minute, then stir vigorously. If necessary, continue heating in 30-second bursts until the mixture is glossy and nearly smooth.
  4. Remove the bowl from the heat and immediately fold in the vanilla extract and fine sea salt until fully emulsified.
  5. If using optional mix-ins like walnuts or crushed candy canes, fold them into the mixture now before it begins to set.
  6. Pour the fudge mixture into the prepared pan and smooth the surface with an offset spatula.
  7. Allow the fudge to rest at room temperature for 30 minutes, then transfer to the refrigerator for at least 2 hours until firm.
  8. Use the parchment paper sling to lift the fudge from the pan. Slice into 1-inch squares using a warm, sharp knife.
