Combine the coconut milk, agave and salt in a large saucepan with high sides (use a saucepan that is larger than you think you will need to keep the mixture from boiling over). Bring to a boil over high heat. Adjust the temperature to keep the mixture boiling but not boiling over and let boil for 30 minutes or until the mixture has reduced to about 1 ¾ cups and is a light amber color. You can check by pouring the mixture into a heatproof measuring cup, if it has not reduced enough, just boil a little longer. Let cool and refrigerate for about half an hour.
Line two baking sheets with parchment or waxed paper.
Combine the cooled coconut milk mixture with the gluten free graham style cracker crumbs in a large mixing bowl and stir. Stir in the chocolate chips. Pour the coconut flakes into a bowl or dinner plate.
For each cookie drop about 1 tablespoon of the cookie mixture into the coconut flakes and roll into a ball – a small ice cream scoop (#60) works well for measuring the dough. Place the cookie on the prepared pans and repeat with the remaining mixture.
Put cookies in the refrigerator until hardened, about half an hour.
