When I don’t have pumpkin pie spice, I use the following combination of spices (equivalent to 2 tsp of pumpkin spice): 1 tsp all-spice 1/4 tsp ground cinnamon 1/4 tsp ground nutmeg 1/4 tsp ground ginger 1/4 tsp ground cloves You can adjust to taste. You can also simply use ground cinnamon. Just note that you won’t get the exact flavor profile.
