Ingredients
 

Main Ingredients

  • 2.5 cup granulated sugar
  • 0.5 cup unsweetened cocoa powder natural or Dutch-process
  • 1 cup heavy cream
  • 1 tbsp light corn syrup helps prevent crystallization
  • 6 tbsp unsalted butter cut into pieces
  • 0.25 tsp fine sea salt
  • 2 tsp pure vanilla extract
  • 4 oz bittersweet chocolate, chopped or chocolate chips
  • 0.5 cup chopped walnuts optional

Instructions

Preparation Steps

  • Line an 8-inch square pan with parchment, leaving overhang. Lightly butter the parchment.
  • Whisk sugar, cocoa, cream, corn syrup, and salt in a medium heavy saucepan.
  • Warm over medium heat, stirring until sugar dissolves and mixture looks smooth.
  • Clip on a candy thermometer. Cook without stirring until 236°F, soft-ball stage.
  • Remove from heat. Add butter and vanilla on top but do not stir. Cool to 120°F.
  • Add chopped chocolate. Beat with a wooden spoon until thick and slightly matte.
  • Fold in walnuts if using. Work quickly before the fudge firms up.
  • Scrape into the pan and smooth the top. Let set at room temperature until firm.
  • Lift out using parchment. Cut into small squares with a sharp knife.

Notes

Try swirling 2 tablespoons warmed peanut butter over the top before setting, or add 1 teaspoon espresso powder with the cocoa for a mocha twist. Store fudge tightly covered at cool room temperature for up to 1 week, or freeze up to 2 months.
