Thoroughly rinse the fresh cranberries under cold running water. If using frozen cranberries, use them directly from the freezer.
In a medium saucepan, mix together the cranberries, sugar, water, vanilla extract, and ground cinnamon. Turn the heat to medium and bring to a gentle boil, stirring occasionally.
Once boiling, reduce the heat to low and simmer for 10-15 minutes, or until the cranberries burst and the sauce thickens. Remove from heat and let cool for a few minutes.
Transfer the cranberry sauce to a mixing bowl and allow it to cool to room temperature before refrigerating for at least 1 hour.
In a microwave-safe bowl, combine the dark chocolate chips and coconut oil. Heat in 30-second increments, stirring in between, until fully melted.
Once the cranberry sauce is chilled, use a small cookie scoop or tablespoon to portion out small mounds and arrange them on a parchment-lined baking sheet.
Dip each mound of cranberry sauce into the melted chocolate, ensuring it's fully coated. Allow excess chocolate to drip off before placing back on the sheet.
While the chocolate is still warm, sprinkle a pinch of flaky sea salt on top of each chocolate-dipped cranberry bite.
Transfer the baking sheet to the refrigerator for about 30 minutes, or until the chocolate is fully set.
