Place an oven rack in the center of the oven. Preheat the oven to 375 degrees F. Line 3 baking sheets with parchment paper or silicone liners. Set aside.
In a large bowl, mix together the sugar, coconut, melted butter, flour, vanilla, and salt.
Using a 1/2-ounce cookie scoop or a tablespoon, scoop 6 balls of dough, 3 to 4 inches apart, on each baking sheet. Lightly flatten the tops of the dough. Cook until golden, 8 to 10 minutes. Allow the cookies to cool on the parchment paper, about 15 minutes.
Place the chocolate in a bowl and place over a pan of barely simmering water. Stir until the chocolate has melted. Using a fork, drizzle the tops of the cookies with the melted chocolate. Freeze the cookies until the chocolate has set, about 5 minutes. Remove the cookies from the freezer and store in an airtight container at room temperature.
Cook's Note: If the cookies have baked into one another, use a knife or metal spatula to separate the cookies then allow to cool.
