Pulse cookies and pecans in blender or food processor until they are crumbs. Melt butter (I did this by microwaving for 30 seconds) and mix together crumbs and butter. Press mixture into bottom of a 9"x13" baking pan and bake for about 10 minutes.
*Do not use pumpkin pie mix
**All spices can be replaced with 1 1/2 tablespoons Pumpkin Pie Spice
