Ingredients

Scale

Chocolate Base

  • 2 cups semi-sweet chocolate chips
  • 1 can (14 oz) sweetened condensed milk
  • 2 tbsp unsalted butter (melted)
  • 1 tsp vanilla extract
  • ¼ tsp salt

Marshmallow Swirl

  • 1 cup marshmallow fluff (or marshmallow cream)

Instructions

  1. Prepare the chocolate mixture: In a microwave-safe bowl, combine the semi-sweet chocolate chips, sweetened condensed milk, and melted unsalted butter. Microwave in 30-second intervals, stirring well between each, until the chocolate is fully melted and the mixture is smooth and creamy.
  2. Add flavorings: Stir in the vanilla extract and salt thoroughly to enhance the chocolate’s rich flavor.
  3. Pour into pan: Pour the chocolate mixture evenly into a lined or greased square baking dish, smoothing the surface with a spatula.
  4. Swirl the marshmallow fluff: Dollop spoonfuls of marshmallow fluff over the chocolate surface. Using a knife, gently drag through the fudge mixture to create thick and visible marshmallow ribbons, being careful not to overmix.
  5. Chill and set: Refrigerate the fudge for at least 2 hours or until fully set and firm enough to cut.
  6. Optional toppings: For extra flair, sprinkle crushed graham crackers on top before chilling, or lightly torch the surface after swirling marshmallows to toast them and add a caramelized flavor.
  7. Serve: Once set, cut into clean squares and enjoy your decadent marshmallow swirl fudge.

Notes

  • Use marshmallow fluff instead of mini marshmallows to maintain creamy, distinct swirls rather than melting completely into the fudge.
  • Do not overmix the marshmallow swirl; this keeps the ribbons thick and defined.
  • Allow the fudge to chill fully for at least 2 hours for clean-cut squares.
  • To create a s’mores inspired fudge, add crushed graham crackers on top before chilling.
  • For toasted marshmallow flavor, lightly torch the marshmallow swirl after swirling but before chilling.
