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
  • 1 tsp vanilla extract

Swirl

  • 1 1/4 cups mini marshmallows

Instructions

  1. Prep Your Pan: Line an 8×8-inch square baking pan with parchment paper, leaving a slight overhang on the sides to easily lift out 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 continuously until the chocolate chips and butter have fully melted and the mixture is smooth.
  3. Add Vanilla: Remove the saucepan from heat and stir in the vanilla extract until fully incorporated, ensuring a uniform flavor throughout the fudge.
  4. Fold in Marshmallows: Quickly fold the mini marshmallows into the warm fudge mixture using a spatula. Gently fold just enough to swirl the marshmallows without allowing them to melt completely, preserving their distinct texture.
  5. Transfer to Pan and Swirl: Pour the fudge mixture into the prepared pan. Use a spatula to swirl the marshmallows on top so that some peek through the surface for an attractive, marbled effect.
  6. Chill and Set: Let the pan cool at room temperature for 10 minutes to slightly firm up, then place it in the refrigerator for at least 2 hours until the fudge is fully set and firm to the touch.
  7. Slice and Serve: Once set, lift the fudge out of the pan using the parchment paper overhang. Use a buttered knife to slice the fudge into 16 equal squares, ready to enjoy or gift.

Notes

  • Use parchment paper with overhang for easy removal of fudge from pan.
  • Do not overfold marshmallows to keep some texture and visual appeal.
  • Store fudge in an airtight container in the refrigerator for up to two weeks.
  • Bring fudge to room temperature before serving for a softer bite, if desired.
  • Butter your knife before slicing to get clean, smooth edges on fudge squares.
