This Marshmallow Swirl Fudge is a rich, creamy chocolate treat swirled with soft mini marshmallows for a delightful chewy contrast.

Ingredients

Scale

Fudge Base

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

Flavoring

  • 1 tsp vanilla extract

Add-ins

  • 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 easily lift the fudge out once set.
  2. Melt Chocolate, Milk, Butter, and Salt: In a medium saucepan over low heat, combine chocolate chips, sweetened condensed milk, unsalted butter, and salt. Stir constantly to melt everything evenly until smooth and fully combined.
  3. Add Vanilla: Remove the saucepan from heat and stir in vanilla extract thoroughly to incorporate the flavor evenly.
  4. Fold in Marshmallows: Quickly add mini marshmallows and gently fold them into the chocolate mixture with a spatula, just enough to swirl them in without fully melting.
  5. Transfer to Pan and Swirl: Pour the fudge mixture into the prepared baking pan and use a spatula to gently swirl the marshmallows on top so some peek through for a pretty, textured look.
  6. Chill and Set: Let the pan cool at room temperature for 10 minutes, then transfer it to the refrigerator for at least 2 hours until the fudge is completely set and firm.
  7. Slice and Serve: Once set, lift the fudge out of the pan using the parchment paper overhang and slice into 16 squares using a buttered knife for clean cuts.

Notes

  • Use parchment paper with an overhang to easily lift fudge from the pan.
  • Stir slowly and constantly while melting chocolate to prevent scorching.
  • Fold marshmallows gently to retain their shape and texture within the fudge.
  • Let fudge chill long enough to firm up completely before slicing for clean pieces.
  • Store fudge in an airtight container in the fridge for up to 1 week.
