Arrange pecans in a single layer of a shallow baking pan. Bake 8-10 minutes or until lightly toasted. Stir halfway through baking.
Line the bottom and sides of a 9"x 13"x 2" baking pan with aluminum foil, leaving an overhang on two short sides. Grease the foil.
Whisk together the flour, confectioners' sugar, and cocoa. Add the cold butter, and combine with a pastry blender* until the mixture resembles coarse meal. Press the mixture into the bottom and about 3/4-inch up the sides of the prepared pan.**
Bake the crust for 15 minutes. Remove from the oven and immediately sprinkle chocolate chips evenly over crust. Allow to cool on a wire rack at least 30 minutes.
Place the eggs in a large mixing bowl, and beat lightly. Add the brown sugar, corn syrup, and melted butter. Whisk together until smooth. Stir in the coconut and pecans. Pour evenly over the partially baked crust.
Bake 28-34 minutes, or until the edges are golden and the filling has set. Cool completely on a wire rack. Then, refrigerate for an hour.
Using the foil overhang, lift the bars from the pan and place on a cutting board. Use a sharp knife to cut into bars.

Notes
*You can also mix crust ingredients in a food processor, but I prefer mixing this way.
**Shortbread crusts like this one can be a bit tricky. The mixture will not hold together on its own, but it should hold together when pinched. Be sure your ingredient measurements are accurate, and press the crust firmly into the bottom of the pan.
