Preheat oven 350˚F.
Mix together the melted butter, condensed milk and stir until totally incorporated.
Mix in the egg, vanilla, stir well.
Add the coconut and flaked sea salt.
Mound by tablespoon or more onto a parchment lined cookie sheet (they will stick to a bare sheet, you must line them).
Bake for 15 minutes or until golden brown, they can take up to 20 minutes.
Let them cool on the sheet for at least 15 minutes and then transfer to a wire rack. You can drizzle them with melted chocolate if that is your thing.
