Ingredients

  • 12 ounces semi-sweet chocolate chips
  • 1 16-ounce tub chocolate frosting*
  • 3/4 cup chopped walnuts
  • 1/8 teaspoon salt optional

Instructions

  1. Spray an 8-inch square baking dish with cooking spray and set aside.
  2. Place the chocolate chips in a large microwave-safe bowl and heat in 30-second intervals, stirring well after each interval, until smooth. (Sometimes they don’t melt well-just keep stirring and eventually they’ll get smooth.)
  3. Remove the lid and foil top from the tub of frosting and heat until pourable, about 20 to 30 seconds.
  4. Pour the frosting over the melted chips, then add the walnuts and the salt (if using). Quickly stir to combine, then pour into the prepared baking dish and smooth the top.
  5. Refrigerate for 2 hours, or until set. Remove from the fridge and let sit at room temperature for 15 to 20 minutes (if you don’t let it sit the fudge can be a little crumbly when you slice it).
  6. Slice and serve.

Recipe Notes

  • Uneaten fudge can be stored in an airtight container, layered with wax paper, in the fridge for up to 1 week.
  • It can also be stored in the freezer (again in an airtight container) for about two months.
  • *I used Duncan Hines creamy chocolate frosting.
