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 (a heatproof bowl set over a saucepan of simmering water, ensuring the bowl does not touch the water) or by microwaving in short 30-second intervals, stirring thoroughly after each, until perfectly smooth.
03 - Pour the melted dark chocolate onto the prepared parchment-lined baking sheet. Using an offset spatula, uniformly spread the chocolate into a ¼-inch thick rectangle, aiming for an even layer.
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 base to create a marbled visual effect.
05 - Immediately and evenly sprinkle the dried cranberries, diced apricots, chopped pistachios, chopped almonds, freeze-dried berries, and edible rose petals or sprinkles over the still-wet chocolate surface.
06 - Gently press the various toppings into the chocolate to ensure they adhere securely as the bark sets.
07 - Allow the chocolate bark to set completely. This can be achieved by leaving it at room temperature for approximately 1 hour, or by refrigerating it for a quicker 30-minute period until firm.
08 - Once fully set, break the chocolate bark into irregular pieces suitable for serving. It can be enjoyed immediately or packaged for gifting.
