1. Preheat oven to 350°. Bake pecans in a single layer in a shallow pan 8 to 10 minutes or until lightly toasted and fragrant, stirring halfway through.
2. Line bottom and sides of a 13- x 9-inch pan with heavy-duty aluminum foil, allowing 2 to 3 inches to extend over sides. Lightly grease foil.
3. Pulse flour and next 3 ingredients in a food processor 5 to 6 times or until mixture resembles coarse meal. Press mixture on bottom and 3/4 inch up sides of prepared pan.
4. Bake crust at 350° for 15 minutes. Remove from oven, and sprinkle chocolate morsels over crust. Cool completely on a wire rack (about 30 minutes).
5. Whisk together brown sugar and next 3 ingredients until smooth; whisk in bourbon. Stir in coconut and toasted pecans, and spoon into prepared crust.
6. Bake at 350° for 25 to 30 minutes or until golden and set. Cool completely on a wire rack (about 1 hour). Chill 1 hour. Lift baked bars from pan, using foil sides as handles. Transfer to a cutting board; cut into bars.
