These come out best when using a light colored metal pan. If using a dark pan or a glass pan, you may need to shorten the bake time by a few minutes to avoid overbrowning.
For Crust: Combine flour, sugar and corn starch in a medium bowl. Cut in butter until mixture is crumbly. Press into a greased 13 x 9-inch pan.
Bake in a preheated 350°F oven for 15 to 18 minutes or until crust is lightly browned.
For Filling: Beat eggs, corn syrup, peanut butter, vanilla and salt in a medium mixing bowl. Stir in coconut and chocolate chips. Pour over crust. Return to oven.
Bake an additional 20 to 25 minutes, or until mixture is golden. Cool on wire rack and cut into bars.
