This Marshmallow Swirl Fudge recipe combines decadent semi-sweet chocolate with sweetened condensed milk and a smooth swirl of marshmallow fluff to create a rich, creamy, and irresistible treat. Perfect for chocolate lovers craving a fudgy texture with gooey marshmallow highlights, this no-bake dessert is simple to prepare and ideal for any occasion.

  • Total Time: 2 hours 15 minutes
  • Yield: 16 servings

Ingredients

Fudge Base

  • 2 cups (12 oz) semi-sweet chocolate chips
  • 1 can (14 oz) sweetened condensed milk
  • 2 tablespoons unsalted butter, melted
  • 1 teaspoon pure vanilla extract
  • ¼ teaspoon salt

Swirl

  • 1 cup marshmallow fluff (or marshmallow cream)

Instructions

  1. Prepare the pan: Line an 8×8-inch baking dish with parchment paper, ensuring some paper hangs over the edges. This will help you easily lift the fudge out once set.
  2. Melt the base ingredients: In a medium saucepan over low heat, combine the chocolate chips, sweetened condensed milk, and melted butter. Stir constantly for 3-5 minutes until the mixture is smooth and fully melted. Remove from heat and stir in the vanilla extract and salt to enhance flavor and balance sweetness.
  3. Pour and spread the fudge: Transfer the smooth chocolate mixture into the lined baking dish. Use a spatula to spread it evenly, creating a uniform layer.
  4. Add marshmallow swirls: Drop spoonfuls of marshmallow fluff onto the warm fudge. Use a knife to gently swirl the marshmallow into the chocolate mixture, creating beautiful swirled patterns without overmixing.
  5. Chill and set: Place the fudge in the refrigerator for at least 2 hours, allowing it to firm up. Once set, use the parchment paper overhangs to lift the fudge from the pan and cut into 16 squares.

Notes

  • Use parchment paper for easy removal and cleaner cuts.
  • Swirling the marshmallow gently creates an attractive marbled effect; avoid overmixing.
  • Store fudge in an airtight container in the refrigerator for up to 1 week.
  • Allow fudge to come to room temperature slightly before serving for best texture.
  • You can substitute semi-sweet chocolate chips with milk chocolate for a sweeter fudge.
