Add the desiccated coconut to a medium bowl.
Add the coconut milk.
Mix until moist and packable.
Open each Medjool date along one side and remove the pit if necessary.
Divide the coconut mixture between the 15 dates.
Press the filling firmly into each date.
If necessary, refrigerate the stuffed dates for about 10 minutes so they're easier to dip.
Melt the dark chocolate gently until completely smooth.
Dip each stuffed date into the chocolate.
Turn until fully coated.
Lift with a fork and allow excess chocolate to drip away.
Place on parchment.
Sprinkle with additional coconut while the chocolate is still wet, if desired.
Refrigerate for approximately 15 minutes, until the coating is firm.
Serve chilled or let stand briefly for a softer center.
