Preheat the oven to 350°F. Line 2 large baking sheets with a silicone baking mat or parchment paper.
In a medium size mixing bowl, mix together the coconut, flour and salt.
Add the sweetened condensed milk, beaten egg white and vanilla. Mix well. The mixture will be stiff.
Use a 1 ½-2 tablespoon cookie or ice cream scoop to divide the cookie dough leaving at least 2 inches apart on the baking pan. Bake for 16-18 minutes or until golden. (You can also drop using a tablespoon.)
Remove from the oven and let stand on the pan for 1-2 minutes, then gently press a candy kiss into the center.
Remove immediatley to a wire rack to cool completely.
