Ingredients:

  • 3 cups (510g) semi-sweet chocolate chips
  • 3 packets (110g) hot cocoa mix
  • 1/4 cup (25g) unsweetened Dutch-processed cocoa powder
  • 1 can (14 oz / 397g) sweetened condensed milk
  • 1/4 cup (56g) unsalted butter, cubed
  • 1 tsp (5ml) pure vanilla extract
  • 1/4 tsp fine sea salt
  • 1 cup (50g) mini marshmallows

Instructions:

  1. Line an 8x8-inch square baking pan with parchment paper, leaving an inch of overhang on the sides for easy removal.
  2. In a small bowl, sift together the dry hot cocoa mix and the unsweetened cocoa powder until no lumps remain.
  3. In a heavy-bottomed saucepan or large microwave-safe glass bowl, combine the sweetened condensed milk, cubed butter, and chocolate chips.
  4. Heat on low, stirring constantly, until the mixture is glossy and smooth. Remove from heat and allow the residual warmth to finish melting the chocolate.
  5. Stir in the vanilla extract, sea salt, and the sifted cocoa powder mixture until the fudge is glossy and smooth.
  6. Let the mixture sit for about 1 minute so it isn't scorching hot. Fold in half of the mini marshmallows — they will melt slightly, creating white streaks of sweetness.
  7. Transfer the fudge into your prepared pan, smoothing the top with your spatula. The surface should look like polished dark marble.
  8. Press the remaining mini marshmallows into the top of the fudge while it is still warm so they adhere properly.
  9. Chill in the refrigerator for at least 3 hours before lifting the parchment sling and slicing into 36 squares.
