Line 13x9-inch pan with foil, with ends of foil extending over sides; spray with cooking spray. Beat first 4 ingredients with mixer until blended. (Dough will be thick.) Press half onto bottom of prepared pan. Bake 10 min.
Sprinkle half each of the chopped chocolate and nuts over crust. Microwave peanut butter in small microwaveable bowl on HIGH 1 min., stirring after 30 sec.; spread over nuts on crust.
Roll remaining dough into 13x9-inch rectangle between 2 sheets of waxed paper. Peel back top layer of waxed paper; flip dough over dessert. Remove remaining waxed paper. Sprinkle with remaining chocolate and nuts; press gently into dough to secure.
Bake 15 min. or until lightly browned. Cool completely. Refrigerate several hours or until firm. Use foil handles to remove dessert from pan before cutting into bars.
Note from the KRAFT Kitchens
We appreciate your comments and changed our method. To create nice even layers, microwave the peanut butter and roll out the top layer of dough as directed. Thank you for all of your helpful suggestions!
Make these bars a day ahead. Then, just cut them, put them on a serving platter and you're ready to go!
