Preheat oven to 350F. Line a baking sheet with parchment paper.
In a food processor, combine the oats, coconut, and chia seeds. Process until broken down into fine pieces but not quite flour.
Add pumpkin, nut butter, syrup, spice, baking powder, salt, and vanilla. Process until combined into a sticky dough.
Add the chocolate chips (and pecans, if using) and process briefly just to combine.
Using a cookie scoop, roll dough into 1" balls. Place on prepared baking sheet and press down gently to shape into a cookie form - cookies will not spread.
Bake for 11-13 minutes, or until lightly browned.
Let cool for about 10 minutes, then enjoy!
