01 - Line a baking sheet with parchment paper and set aside.
02 - In a medium bowl, combine the chopped Medjool dates, roughly chopped pistachios, and crisp rice cereal. Toss until evenly distributed.
03 - In a heatproof bowl set over a saucepan of simmering water, melt the dark chocolate and coconut oil together, stirring until smooth. Alternatively, microwave in 30-second bursts, stirring between each interval, until fully melted and glossy.
04 - Pour the melted chocolate over the date-pistachio-cereal mixture and stir thoroughly, ensuring every piece is completely coated.
05 - Using a tablespoon or small cookie scoop, drop spoonfuls of the coated mixture onto the prepared baking sheet, spacing them about 1 inch apart.
06 - Sprinkle each cluster with additional chopped pistachios and a light pinch of flaky sea salt.
07 - Refrigerate the clusters for at least 30 minutes, or until the chocolate is firm and fully set.
08 - Transfer to an airtight container and store in the refrigerator for up to 1 week.
