🧑‍🍳 Instructions

  1. Prep the trays
    Line two baking trays with parchment or wax paper and set aside.

  2. Make the chocolate base
    In a medium saucepan, combine:

  3. 1½ cups (300 g) granulated sugar
  4. ½ cup (120 mL) milk
  5. ½ cup (113 g) unsalted butter

  6. ¼ cup (25 g) unsweetened cocoa powder
    Place over medium heat, stirring occasionally until it comes to a full boil.

  7. Boil precisely
    Once the mixture reaches a rolling boil, stop stirring and let it boil exactly 60 seconds. Use a timer for precision.

  • Timing is key: Boil the chocolate mixture for exactly 60 seconds—no more, no less—for the best consistency.
  • Work quickly: The mixture sets fast as it cools. Use a cookie scoop to portion evenly and efficiently.
  • Customization ideas: Stir in mix-ins like:
  • 1 tsp instant coffee granules
  • ½ cup (45 g) shredded coconut
  • A handful of roasted peanuts
  • Press M&Ms, sprinkles, or chocolate chips on top while still warm
