In a large bowl, toss together the flour, salt, baking powder, baking soda, 1 and 1/2 teaspoons cinnamon and pumpkin pie spice. Pour the wet ingredients into the dry ingredients and mix together with a large spoon or rubber spatula. The dough will be very soft. Fold in the cinnamon chips. They may not stick to the dough because of the melted butter, but do your best to evenly disperse them in the dough. Cover the dough and chill for 30 minutes, or up to 3 days. Chilling is mandatory.
