Ingredients

  • 6 ounces (170 grams) unsweetened chocolate, from a high-quality chocolate bar, hand broken into pieces
  • 4 ½ cups 18 ounces or 510 grams) confectioners' sugar, sifted if necessary
  • 1 ½ cups (3 sticks or 12 ounces or 340 grams) cold unsalted butter
  • 6 Tablespoons (3 ounces or 85 grams) cold whole milk
  • 1 Tablespoon pure vanilla extract
  • ¼ teaspoon kosher salt

Equipment

  • A food processor

Instructions
 

  • Prep the chocolate for the frosting. In a food processor, pulse the chocolate for a few seconds at a time until chopped into ½- to 1-inch pieces.
  • Melt the chocolate. Transfer the chocolate to the top of a double boiler or to a heatproof bowl set over a medium, heavy-bottomed saucepan filled with a few inches of simmering water (be sure the bottom of the bowl does not touch the water).
    Cook over medium heat, using a heatproof rubber spatula to stir the mixture and scrape the sides of the bowl occasionally, until the chocolate has melted, about 10 minutes.
    Set the top of the double boiler or the bowl on a wire rack and let the chocolate cool while you prep the other ingredients.
  • Prep the rest of the ingredients. In the food processor, combine the confectioners’ sugar, butter, milk, vanilla, and salt.
  • Add the chocolate, then process all the ingredients to make the frosting. Pour in the melted chocolate and pulse briefly to combine, then process until the frosting is creamy, smooth, and light brown in color, about 5 minutes. Scrape down the bottom and sides of the bowl with a rubber spatula, then process for an additional 30 seconds.
  • Use immediately. Use an offset spatula to cover your favorite cake recipe with the chocolate fudge frosting.
    The chocolate fudge frosting will keep under a cake dome at room temperature for up to 1 day. After that, refrigerate any cake with frosting in an airtight container for up to 2 more days.
