Pour the melted dark chocolate onto the prepared baking sheet, spreading it evenly.
Sprinkle mixed nuts over the dark chocolate layer.
Melt the white chocolate chips and drizzle over the dark chocolate.
Add colorful sprinkles and dried fruits on top.
Use a toothpick to swirl the chocolates together.
Sprinkle sea salt over the top.
