Equipment

  • Kitchen Scale (optional)
  • 8x8 Baking Pan
  • Candy Thermometer (optional)

Ingredients

  • cup evaporated milk 151 grams (about ½ can)
  • 1 cup granulated sugar 200 grams
  • ¼ teaspoon kosher salt
  • ¾ cup semisweet chocolate chips 128 grams, Ghirardelli recommended
  • ¾ cup dark chocolate chips 128 grams, Ghirardelli recommended
  • ¼ cup unsalted butter 57 grams (½ stick)
  • 4 ounces marshmallow fluff 113 grams (about ½ jar)
  • 1 teaspoon pure vanilla extract 4 grams

Instructions

  • This recipe moves fast so have all of your ingredients measured and ready to go before you get started!
  • Line an 8x8-inch baking pan with parchment paper and spray well with nonstick spray. Set aside (close by).
  • In a medium saucepan (2-quart size) set over medium heat, heat the evaporated milk, sugar, and salt together until boiling (stirring constantly). Let boil over medium heat, still stirring constantly, for 5 minutes. Don’t remove from heat before the 5 minutes are up or the fudge will not firm up later during chilling.

Notes

  • Prepare and measure all of your ingredients before starting; this recipe goes fast!
  • Use high-quality chocolate, such as Ghirardelli; do NOT use any chocolate chips labeled "baking chips" as they will not melt properly.
  • To prevent the sugar mixture from burning, use a heavy-bottomed pot, such as a Dutch oven. 
  • Once boiling, stir the sugar mixture constantly!
  • Use a candy thermometer to check the temperature of the sugar; it should be 234-236°F.
  • If the mixture is cooked above 236°F, your fudge may turn out crumbly. 
  • Let the fudge cool to room temperature before cutting to prevent cracking. 
Storage: Store marshmallow fluff fudge in an airtight container at room temperature or in the refrigerator for up to 1 week. Freeze for up to 2 months.
