01 - Line a standard baking sheet with parchment paper, ensuring it covers the entire surface to prevent sticking.
02 - Gently melt the chopped dark chocolate using a double boiler method, or by microwaving in 30-second increments, stirring thoroughly after each interval, until completely smooth and free of lumps.
03 - Pour the melted dark chocolate onto the prepared baking sheet. Using an offset spatula, carefully spread the chocolate into a uniform ¼-inch thick rectangle.
04 - If utilizing white chocolate, melt it using the same method as the dark chocolate. Drizzle the melted white chocolate artistically over the dark chocolate layer to create an elegant marbled effect.
05 - Immediately and evenly sprinkle the dried cranberries, chopped apricots, pistachios, almonds, optional freeze-dried berries, and edible rose petals or sprinkles over the still-wet chocolate surface.
06 - Gently press the assorted toppings into the chocolate layer to ensure they firmly adhere once the bark sets.
07 - Allow the chocolate bark to set undisturbed at room temperature for approximately 1 hour, or accelerate the process by refrigerating for 30 minutes, until the chocolate is completely firm.
08 - Once fully set, carefully break the chocolate bark into irregular, bite-sized pieces. Serve immediately, or store for later enjoyment or gifting.
