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 fluid.
03 - Pour the melted semisweet chocolate onto the prepared baking sheet. Use an offset spatula to spread evenly into a rectangle approximately 1/4 inch thick.
04 - In separate microwave-safe bowls, melt the white chocolate chips and assorted candy melts. Microwave each in 20-second intervals, stirring between intervals, until completely smooth.
05 - Drop spoonfuls of the melted white chocolate and colorful candy melts randomly over the dark chocolate base. Drag a toothpick or skewer through the chocolates in a figure-eight or circular motion to create decorative swirls and a marbled effect.
06 - While the chocolate remains warm and sticky, immediately scatter mini candy-coated chocolates, candy eyes, and Halloween sprinkles evenly across the surface. Press gently to ensure adherence.
07 - Allow the bark to cool completely at room temperature until firm, approximately 20 to 30 minutes. For faster setting, refrigerate for 10 to 15 minutes.
08 - Once fully set and firm, break the bark into irregular, rustic-sized pieces by hand or use a sharp knife to cut clean sections.
