In a large bowl, whisk the egg whites and vanilla until frothy and light in consistency.
Add the remaining ingredients except for the chocolate. Mix until everything is thoroughly combined.
Allow the mixture to rest in the refrigerator for about 30 minutes, and then mix again to incorporate any condensed milk that went to the bottom of the bowl.
Set oven to 350°F.
Use a small scoop or a spoon to form coconut cookie balls (about two tablespoons worth for each cookie).
Roll the balls to make the coconut compact so the macarons don't fall apart.
Bake the cookies on a sheet tray lined with parchment (or spray and foil) at 350°F for 17 to 20 minutes until golden brown. Allow to cool before taking off of tray.
In the microwave, melt the chocolate chips in 10-second increments, stirring in between cooking, until melted and smooth.
Use a spoon or a piping bag to drizzle lines of chocolate over the coconut macaroons. You can also dunk the bottom or top of the cookies in the chocolate instead.
