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 Mix-In

  • 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 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 constantly until the mixture is fully melted and smooth, ensuring the chocolate doesn’t burn.
  3. Add Vanilla: Remove the pan from the heat and stir in the vanilla extract until fully combined to enhance the flavor depth.
  4. Fold in Marshmallows: Quickly add the mini marshmallows and gently fold them into the fudge mixture using a spatula, just enough to create a swirl effect without melting them completely.
  5. Transfer to Pan and Swirl: Pour the fudge mixture into the prepared baking pan. Use the spatula to swirl the top so some marshmallows peek through, giving the fudge a decorative 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, or until the fudge is fully set and firm.
  7. Slice and Serve: Once set, lift the fudge out of the pan using the parchment paper overhang. Slice into 16 squares with a buttered knife for clean cuts and serve.

Notes

  • Make sure to stir constantly while melting the chocolate mixture to avoid scorching or burning.
  • For extra flair, you can sprinkle a handful of additional mini marshmallows on top before chilling.
  • Store fudge in an airtight container in the refrigerator for up to 1 week.
  • Use a buttered knife to slice the fudge cleanly without sticking.
  • Allow fudge to come to room temperature for a few minutes before serving for the best texture.
