Make your own pumpkin spice coffee by adding pumpkin pie spice to the grounds before brewing. You can make your own spice:
4 T. cinnamon
4 tsp. ground nutmeg
4 tsp. ground ginger
3 tsp. ground allspice
Stir all spices together and keep in an airtight jar (re-use an empty spice jar).
Experiment and come up with your own combination, maybe adding cloves or chili powder or cocoa - whatever you like!
