Equipment

  • 8x8 inch square baking dish
  • parchment paper
  • large, heavy-bottomed saucepan
  • butter knife or skewer
  • cutting board

Ingredients
  

Fudge Base

  • 14 ounce sweetened condensed milk
  • 12 ounces semi-sweet chocolate chips good quality makes a difference!
  • 1/2 cup unsalted butter
  • 1 teaspoon vanilla extract
  • Pinch salt

Marshmallow Swirl

  • 7 ounces marshmallow creme or 2 cups mini marshmallows, melted

Instructions
 

Preparation

  • Line an 8x8 inch baking dish with parchment paper, allowing an overhang to easily remove the fudge later.

Cooking

  • In a large saucepan over medium-low heat, melt the sweetened condensed milk, chocolate chips, and butter, stirring until smooth and glossy.
  • Remove from heat, then stir in the vanilla extract and salt until well combined.
  • Pour the chocolate mixture evenly into the prepared baking dish.
  • Drop spoonfuls of marshmallow creme over the hot fudge, or drizzle with melted mini marshmallows if using.
  • Gently swirl the marshmallow into the chocolate fudge with a knife or skewer, aiming for distinct ribbons rather than overmixing.

Finishing

  • Refrigerate the fudge for at least 2-3 hours until it is completely firm.
  • Lift the fudge from the pan using the parchment paper, then cut into 1-inch squares and serve.

Notes

For best results, use good quality chocolate chips as they significantly impact the fudge's flavor and texture. Ensure the marshmallow and chocolate are warm enough to swirl easily without fully combining. These fudge delights can be stored in an airtight container at room temperature for up to a week, or refrigerated for longer freshness.
