For topping cream butter, salt and brown sugar spread evenly over the bottom of a 9-inch cake pan, then scatter pecan halves over the topping and set aside.
Using a rolling pin, roll out the dough int a ⅛ inch thick rectangle (about 12"x8") add flour as needed to keep the dough from sticking to the rolling pin or surface.*
While the dough is resting cream butter, cinnamon and sugar, then spread the mixture evenly over the dough and if you're using pecans in the filling add them now by sprinkling them over the filling.
