05 - Add the wet ingredients to the dry ingredients, mixing until just combined. Fold in shredded coconut.
06 - Scoop tablespoon-sized amounts of dough and roll into balls. If desired, roll each ball in additional sugar for a sparkly finish.
07 - Place dough balls 2 inches apart on prepared baking sheets. Gently flatten each ball with your palm.
