01 - Line a baking sheet with parchment paper to prevent sticking and ensure easy removal of the finished bark.
02 - Place semisweet chocolate chips in a microwave-safe bowl. Microwave in 30-second intervals, stirring thoroughly after each interval, until completely smooth and glossy.
03 - Pour the melted semisweet chocolate onto the prepared baking sheet. Spread evenly with a spatula to form a rectangle approximately 1/4 inch thick.
04 - In separate microwave-safe bowls, melt white chocolate chips and assorted candy melts. Microwave each in 20-second intervals, stirring between intervals, until smooth.
05 - Drop spoonfuls of melted white chocolate and colorful candy melts randomly over the dark chocolate base. Drag a toothpick or skewer through the chocolates in swirling motions to create a marbled effect.
06 - While the chocolate is still warm and soft, immediately scatter candy-coated chocolates, candy eyes, and Halloween sprinkles evenly over the surface.
07 - Allow the bark to set at room temperature until firm, approximately 20-30 minutes. For faster setting, refrigerate for 10-15 minutes.
08 - Once completely set and firm, break the bark into irregular, rustic-sized pieces. Arrange on a serving platter or store in an airtight container.
