01 - Line a baking sheet with parchment paper to prevent sticking and ensure easy removal.
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. Use an offset spatula to spread evenly into a rectangle approximately 1/4 inch thick.
04 - In separate microwave-safe bowls, melt white chocolate chips and colorful candy melts. Microwave each in 20-second intervals, stirring between intervals, until smooth and pourable.
05 - Drop spoonfuls of melted white chocolate and 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 a marbled, swirled pattern.
06 - Immediately sprinkle mini candy-coated chocolates, candy eyes, and Halloween sprinkles evenly over the warm bark surface while chocolate remains melted to ensure toppings adhere properly.
07 - Allow bark to cool and set at room temperature for approximately 30 minutes, or refrigerate for 10-15 minutes until completely firm and chocolate is no longer glossy.
08 - Once fully set, break the bark into irregular, rustic-sized pieces by hand. Serve immediately or store in an airtight container.
