Spray a 9" x 13" baking dish with cooking spray.  Line it with parchment paper, pushing paper down so the spray helps hold it in place.  Unroll dough and place rectangle in dish on parchment paper stretching the rectangle to fit and pinching seams closed if necessary.

Bake in a preheated 350 degree oven for 15 minutes or until dough is golden.

Top dough with even layers of coconut, chips and candy.  Slowly pour milk over all, coating everything.  Return to oven and bake for 25-30 minutes until set and bubbling.  Cool.

When cookies are cool carefully lift parchment paper out of dish and continue to cool.  Can be refrigerated to speed up cooling.  Once cool, cut into bars or squares.
