Combine 1 cup oats, pumpkin puree, honey, flaxseed meal, nut or seed butter, pumpkin pie spice and cinnamon into a food processor and process until all ingredients are incorporated.
Transfer into a large bowl. Add in 1/2 cup rolled oats and chocolate chips. Mix with your hands until all ingredients are incorporated. Take a handful of the mixture (an ice cream scoop size) and start to roll into balls.
Refrigerate for 1-2 hours and then enjoy! Sprinkle some pumpkin spice on top if you like!
