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. Heat in 30-second intervals, stirring thoroughly after each interval, until completely smooth and fully melted.
03 - Pour the melted semisweet chocolate onto the prepared baking sheet. Use a spatula to spread it evenly into a rectangular layer approximately 1/4 inch thick.
04 - In separate microwave-safe bowls, melt the white chocolate chips and colorful candy melts. Heat each in 20-second intervals, stirring between intervals, until smooth and fully melted.
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 swirling motion to create a marbled effect.
06 - Immediately scatter the candy-coated chocolates, candy eyes, and Halloween sprinkles over the warm chocolate. Press gently to ensure they adhere to the surface.
07 - Allow the bark to set at room temperature for approximately 30 minutes, or refrigerate for 10 to 15 minutes until completely firm and solid.
08 - Once fully set, break the bark into irregular, bite-sized pieces using your hands or a knife. Serve immediately or store in an airtight container.
