In a large bowl combine the butter and sugar with a rubber spatula. Add the eggs, egg yolk, and vanilla and stir until combined. Stir in the salt and flours. The mixture will be a thick dough-like batter. Stir in 3/4 of the coconut and chocolate chunks.
Spread the batter into the prepared pan. Sprinkle with the remaining coconut and chocolate chunks, pressing into the batter slightly. Bake for about 40 minutes, or until set but still gooey.
Allow to cool before cutting into bars using a big sharp knife or a big plastic knife. For cleaner cuts, wipe the blade under hot running water between cuts.
