Place the pitted dates into the bowl of a large food processor fitted with an "S" blade, then process until they form a sticky ball. Use a spatula to break up the date mixture a bit, then add in the sunflower seed butter, shredded coconut, and salt if using. Process again until a sticky batter is created.
Scoop the dough by tablespoons and roll them into balls. Arrange them on a flat plate or baking sheet lined with parchment paper. Roll the balls in extra shredded coconut, if you want to, then place them in the fridge or freezer to firm up a bit. These balls will keep well in an airtight container in the fridge for up to a month, or in the freezer for up to 6 months.
