Ingredients Equipment Method Notes

Ingredients
  

  • 1 1/2 cups semi-sweet chocolate chips
  • 1 1/2 cups milk chocolate chips
  • 1 can (14 oz) sweetened condensed milk
  • 2.55 oz hot chocolate mix (3 envelopes)
  • 4 tbsp salted butter, cut into pieces
  • 2 tsp pure vanilla extract
  • 4 cups miniature marshmallows, divided
  • 1/2 cup semi-sweet chocolate chips (for drizzle)
  • 2 tsp vegetable oil

Equipment

  • 8x8-inch baking dish
  • parchment paper
  • Microwave-safe bowl
  • spatula
  • measuring cups and spoons
  • Sharp knife

Method
 

  1. Line an 8×8-inch baking dish with parchment paper, leaving an overhang for easy removal. Lightly coat with nonstick spray.
  2. Add semi-sweet chips, milk chocolate chips, sweetened condensed milk, hot chocolate mix, and butter to a microwave-safe bowl. Microwave 1 minute, stir, then microwave in 45-second intervals until melted (2½–3 minutes total).
  3. Stir in vanilla extract until incorporated.
  4. Gently fold 2 cups miniature marshmallows into the chocolate mixture.
  5. Microwave for 20–30 seconds to help the marshmallows soften and distribute.
  6. Spread mixture into the prepared pan.
  7. Sprinkle remaining 2 cups marshmallows over the top and press lightly.
  8. Cover and refrigerate for at least 2 hours, until firm.
  9. Lift fudge out with parchment and transfer to a cutting board.
  10. Melt 1/2 cup semi-sweet chocolate chips with vegetable oil in the microwave for 30 seconds, stirring until smooth.
  11. Drizzle melted chocolate over the marshmallows and let set.
  12. Slice into 25 squares and refrigerate until serving.

Notes

For the cleanest cuts, run a sharp knife under hot water, dry it, and slice while the fudge is cold. This helps achieve smooth, professional edges—perfect for gifting or photography.
