Line a small baking sheet or plate with parchment paper to prevent sticking.
In a heat-proof glass bowl, combine the dark chocolate chips and coconut oil.
Microwave the chocolate mixture in 30-second intervals, stirring thoroughly between each session until the mixture is completely homogenous and fluid.
Fold the sunflower seeds into the melted chocolate using a spatula until every seed is thoroughly coated.
Using a tablespoon, scoop the mixture into 12 distinct mounds onto the prepared parchment paper.
Garnish the top of each bite with a small pinch of flaky sea salt while the chocolate is still wet.
Transfer the baking sheet to the refrigerator and chill for 30 minutes, or until the bites are fully set and firm to the touch.
