Line a baking sheet or a pan with parchment paper. Using a sharp knife, finely chop the chocolate.
Place chocolate and coconut oil in a microwave-safe bowl. Heat chocolate in 30-second intervals, stirring between each, until melted and smooth.
Spread chocolate into an even layer on the prepared pan. Evenly distribute the nuts, seeds, and dried fruit on the melted chocolate.
Refrigerate for 30 minutes or let it cool at room temperature or until hardened.
Once completely set, remove the parchment paper and break the bark into pieces.
