Marshmallow Swirl Fudge is a delightful, creamy treat combining rich semi-sweet chocolate with soft swirls of mini marshmallows. This easy-to-make dessert is perfect for satisfying your sweet tooth with its chewy texture and beautiful marble effect, ideal for sharing or gifting.


Ingredients

Scale

Main Ingredients

  • 3 cups semi-sweet chocolate chips
  • 1 (14 oz) can sweetened condensed milk
  • 2 tbsp unsalted butter
  • 1 tsp vanilla extract
  • 1/8 tsp salt
  • 1 1/4 cups mini marshmallows


Instructions

  1. Prep Your Pan: Line an 8×8-inch square baking pan with parchment paper, leaving a little overhang on the sides to allow easy removal of the fudge later.
  2. Melt Chocolate, Milk, Butter, and Salt: In a medium saucepan over low heat, combine the semi-sweet chocolate chips, sweetened condensed milk, unsalted butter, and salt. Stir constantly until the mixture is fully melted, smooth, and well combined without overheating.
  3. Add Vanilla: Remove the pan from heat and stir in the vanilla extract until fully incorporated, enhancing the fudge’s flavor.
  4. Fold in Marshmallows: Quickly add the mini marshmallows and gently fold them into the chocolate mixture using a spatula. Fold just enough to create swirls without completely melting the marshmallows.
  5. Transfer to Pan and Swirl: Pour the fudge mixture into the prepared baking pan. Use your spatula to gently swirl the top so some marshmallows peek through, creating a beautiful pattern.
  6. Chill and Set: Let the pan cool at room temperature for 10 minutes before transferring it to the refrigerator. Chill for at least 2 hours or until the fudge is fully set and firm.
  7. Slice and Serve: Once set, use the parchment paper overhang to lift the fudge out of the pan. Slice into 16 squares using a buttered knife for clean cuts, then serve.

Notes

  • Don’t overheat the chocolate as it may seize; stir constantly over low heat.
  • Add marshmallows last to prevent them from completely melting, preserving the swirl effect.
  • Use parchment paper in the pan to easily remove the fudge and cut it cleanly.
  • A buttered knife helps in making cleaner cuts without sticking.
  • Store fudge in an airtight container in the fridge to keep it soft and fresh.
  • Swap semi-sweet chocolate chips with dark or milk chocolate for flavor variation.
  • Use marshmallow fluff if mini marshmallows are unavailable.
  • Add crushed peppermint, chopped nuts, or peanut butter chips for added texture and flavor.
  • For a dairy-free version, use vegan condensed milk and vegan chocolate chips.
  • Make the fudge up to 5 days in advance; it also freezes well for up to 3 months.
