Ingredients
  

For the Chocolate Fudge Base:

  • 2 cups 12 oz semi-sweet chocolate chips - provides the rich chocolate foundation
  • 1 can 14 oz sweetened condensed milk creates the perfect fudgy texture
  • 2 tablespoons unsalted butter melted - adds richness and smooth mouthfeel
  • 1 teaspoon pure vanilla extract - enhances the chocolate flavor
  • ¼ teaspoon salt - balances the sweetness

For the Marshmallow Swirl:

  • 1 cup marshmallow fluff or marshmallow cream - creates those gorgeous, gooey swirls

Instructions
 

  • Line an 8×8-inch baking dish with parchment paper, leaving some paper hanging over the edges to help you remove the fudge later.
  • In a medium saucepan over low heat, melt the chocolate chips, sweetened condensed milk, and butter together. Stir constantly until smooth. This takes about 3-5 minutes. Once melted, remove from heat and stir in the vanilla extract and salt.
  • Pour the chocolate mixture into your lined baking dish and spread it evenly with a spatula.
  • Drop spoonfuls of marshmallow fluff on top of the warm chocolate. Use a knife to gently swirl the marshmallow into the chocolate. Don't mix too much - you want to see the swirls.
  • Refrigerate for at least 2 hours until firm. Once set, lift the fudge out using the parchment paper, cut into squares, and enjoy!
