Achieve unbelievably rich, smooth Marshmallow Swirl Fudge using just three main ingredients and a quick stovetop melt. This decadent recipe yields a perfect 8×8 block.

  • Total Time: 35 minutes
  • Yield: 4 servings

Ingredients

  • Semi-sweet chocolate chips: 3 cups (18 oz)
  • Sweetened condensed milk: 1 (14 oz) can
  • Unsalted butter: 4 tablespoons
  • vanilla powder: 1 teaspoon
  • Salt: 1/4 teaspoon
  • Marshmallow crème (or Fluff): 1 (7 oz) jar

Instructions

  1. Step 1: Line an 8×8 inch baking pan with parchment paper, leaving an overhang on the sides for easy removal, then lightly grease the paper.
  2. Step 2: In a heavy-bottomed saucepan over low to medium-low heat, combine the chocolate chips, sweetened condensed milk, and butter. Stir continuously until the mixture is completely melted and smooth. Do not allow the mixture to boil.
  3. Step 3: Remove the pan from the heat immediately. Stir in the vanilla bean paste and salt until fully incorporated. Pour about 3/4 of the fudge mixture into the prepared pan and spread evenly.
  4. Step 4: Drop spoonfuls of the marshmallow crème evenly over the fudge base in the pan. Use a butter knife or a skewer to gently swirl the marshmallow crème into the chocolate mixture without over-mixing; you want distinct ribbons of white.
  5. Step 5: Cover the pan loosely and chill the fudge in the refrigerator for at least 3 to 4 hours, or until completely set. Once set, lift the fudge out using the parchment paper handles and cut into small squares.

Notes

  • Store this fudge in an airtight container in the refrigerator for up to two weeks, or wrap individual pieces tightly for freezing up to two months, thawing overnight before enjoying.
  • Since this fudge does not benefit from true reheating, achieve the perfect soft consistency by resting chilled pieces at room temperature for 10 to 15 minutes before serving.
  • Pair these rich, swirled squares with a strong cup of espresso or crumble them lightly over vanilla ice cream for a delightful textural contrast.
  • When swirling the marshmallow crème, use quick, gentle movements and avoid overworking the mixture; you want defined ribbons of white marshmallow rather than a uniform pale color.
