Combine dry ingredients in a medium bowl. In a separate bowl combine the nut butter and sweetener -heating if needed to make a more stirrable consistency. Add pumpkin and milk and then stir into dry ingredients. Add extra milk if needed, 1 T at a time - dough should be stiff enough that you can roll it into balls.
Roll into bite sized balls and coat in either cinnamon sugar mixture, powdered sugar or just cinnamon. I don't like using refined sugar so I did just cinnamon.
Keep in the refrigerator and enjoy!
