Preheat oven to 325°F (165°C) and line a baking sheet with parchment paper.
Mix shredded coconut, sweetened condensed milk, vanilla, and salt in a bowl.
In a separate bowl, beat egg whites and sugar until stiff peaks form.
Gently fold egg whites into the coconut mixture until combined.
Scoop small mounds onto the prepared baking sheet, spacing slightly apart.
Bake 16–20 minutes until edges turn golden brown.
Cool completely on the tray before removing.
Dip bottoms in melted chocolate or drizzle on top if desired and let set.
