This Marshmallow Swirl Fudge is a luscious and creamy treat that combines semi-sweet chocolate with sweetened condensed milk and fluffy mini marshmallows. The marshmallows are gently folded in at the end, creating beautiful swirls and a delightful chewy texture. Perfect for chocolate lovers looking to make a classic, easy-to-prep fudge that sets firmly in the fridge and slices beautifully into rich, smooth squares.

Ingredients

Scale

Chocolate Mixture

  • 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 for easy removal of 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 and gently to prevent the chocolate from seizing and ensure a smooth, fully melted mixture.
  3. Add Vanilla: Remove the saucepan from the heat and stir in the vanilla extract until completely incorporated.
  4. Fold in Marshmallows: Quickly add the mini marshmallows and fold them in gently with a spatula. Be careful to swirl them just enough so they remain partially intact and do not melt completely.
  5. Transfer to Pan and Swirl: Pour the fudge mixture into the prepared baking pan. Use the spatula to gently swirl the top, allowing marshmallow pieces to peek through for a visually appealing swirl effect.
  6. Chill and Set: Let the pan cool at room temperature for about 10 minutes, then place it in the refrigerator to chill for at least 2 hours until fully set and firm.
  7. Slice and Serve: Once the fudge is set, lift it out of the pan using the parchment paper overhang. Cut into 16 equal squares using a buttered knife to create clean edges and serve.

Notes

  • Do not overheat the chocolate mixture to prevent it from seizing; always cook on low heat and stir constantly.
  • Add marshmallows last and fold gently to keep their shape and create beautiful swirls.
  • Use parchment paper in the pan for easy removal and smoother cutting.
  • A buttered knife cuts the fudge cleaner, preventing stickiness.
  • Store fudge in an airtight container in the fridge for up to 7 days or freeze for up to 3 months layered with parchment paper.
  • Substitutions: Swap semi-sweet chips for milk or dark chocolate, use marshmallow fluff if mini marshmallows are unavailable, or add crushed peppermint or nuts for extra texture.
  • For a dairy-free option, use vegan condensed milk and vegan chocolate chips.
