Preheat oven to 350ยบ. Generously butter a 9 x 13 in baking dish and set aside.
In the bowl of a stand mixer [or other large mixing bowl, if using a hand mixer], cream the butter briefly, and then mix in the sugars until fluffy.
Beat in the eggs and vanilla.
Pour the coconut into the mixing bowl [it gets mixed in with the flour mixture]
In a medium bowl, whisk together the dry ingredients - the flour, salt and baking powder.
With the mixer on low, blend in the coconut and dry ingredients.
Turn the mixer up just a bit and mix in the chocolate chips and nuts.
Spread the dough evenly in the prepared pan, and bake for about 35 minutes, turning halfway through baking time. A toothpick inserted near the center will come out with no more than a few moist crumbs when they are done.
Cool completely and cut into bars. Will keep tightly sealed at room temperature for about a week.
