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 melted.
03 - Pour the melted semisweet chocolate onto the prepared baking sheet. Use a spatula to spread it evenly into a rectangle approximately 1/4 inch thick.
04 - In separate microwave-safe bowls, melt the white chocolate chips and colored 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 colored candy melts randomly over the semisweet chocolate base. Drag a toothpick or skewer through the chocolates in swirling motions to create a marbled pattern.
06 - While the chocolate is still warm and soft, immediately scatter the candy-coated chocolates, candy eyes, and Halloween sprinkles evenly across the surface. Press gently to ensure they adhere.
07 - Allow the bark to cool completely at room temperature until firm, approximately 15-20 minutes. For faster setting, refrigerate for 10-15 minutes.
08 - Once fully set and firm, break the bark into irregular, bite-sized pieces using your hands or a knife. Serve immediately or store for later enjoyment.
