Caramel Pieces of Heaven Recipe

Heat oven to 350ºF; grease a 9- x 13-inch pan. In large bowl, blend all crust ingredients at a low speed until crumbly. Press a little over half of the crumb mixture into the bottom of the pan. Reserve the remaining mixture for the topping. Bake 10 minutes. Meanwhile, in a small bowl, combine caramel topping and flour. Remove the partially baked crust and sprinkle with chocolate chips and nuts. Drizzle caramel mixture over the top. Sprinkle with the remaining crumb topping and bake again for 18 - 22 minutes.
