Preheat your oven to 350°F (175°C).
Spread pumpkin seeds on a baking sheet and roast for 10-15 minutes.
Let pumpkin seeds cool for a few minutes after roasting.
In a microwave-safe bowl, combine chocolate chips and coconut oil.
Melt the chocolate mixture in the microwave in 30-second intervals, stirring each time.
Once melted, remove the bowl from the microwave and stir in the sea salt and optional cinnamon.
Add the roasted pumpkin seeds to the chocolate mixture and stir until well coated.
Transfer the chocolate-covered seeds to a parchment-lined baking sheet.
Refrigerate the seeds for about 30 minutes until the chocolate hardens.
Break apart any clusters and store the seeds in an airtight container.
