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 and Swirl

  • 1 tsp vanilla extract
  • 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 help remove the fudge easily once set.
  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 everything is fully melted and the mixture is smooth.
  3. Add Vanilla: Remove the saucepan from the heat and stir in the vanilla extract until it is fully incorporated into the melted chocolate mixture.
  4. Fold in Marshmallows: Quickly add the mini marshmallows and fold them gently into the mixture with your spatula. This folding should be just enough to swirl the marshmallows through the fudge without melting them completely.
  5. Transfer to Pan and Swirl: Pour the fudge mixture into the prepared baking pan. Use your spatula to gently swirl the top of the fudge so some marshmallows peek through the surface, creating a pretty pattern.
  6. Chill and Set: Allow the fudge to cool at room temperature for about 10 minutes, then transfer the pan to the refrigerator. Chill for at least 2 hours or until the fudge is fully set and firm.
  7. Slice and Serve: Once the fudge is set, lift it out of the pan using the parchment paper overhang. Using a buttered knife, slice the fudge into 16 equal squares and serve.

Notes

  • Be sure to stir the chocolate mixture constantly while melting to prevent burning.
  • For cleaner slices, wipe the knife between cutting each piece.
  • Store leftover fudge in an airtight container in the refrigerator for up to 1 week.
  • You can substitute semi-sweet chocolate chips with dark or milk chocolate depending on your preference.
  • If mini marshmallows are not available, chop larger marshmallows into small pieces to use.
