Rinse the blueberries under cool water and gently pat them dry with a paper towel. Make sure they are completely dry.
In a microwave-safe bowl, combine the chocolate chips and coconut oil. Microwave in 20-30-second increments, stirring after each, until smooth and fully melted. Alternatively, melt the chocolate using a double boiler on the stove.
Incorporate the dry blueberries into the melted chocolate and stir gently for even coating.
With a spoon or fork, transfer small clusters of chocolate-covered blueberries to a parchment-lined baking sheet.
Place the baking sheet in the refrigerator for about 30 minutes, or until the chocolate has set.
Once the chocolate is firm, enjoy the chocolate-covered blueberries or store them in an airtight container in the refrigerator.
