Preheat oven to 350° and line a baking sheet with parchment paper.
In a large bowl, whisk the pumpkin, coconut oil, egg, maple syrup, and vanilla together. In a separate bowl, stir the sugar, almond flour, coconut flour, pumpkin pie spice, cinnamon, baking soda, and salt together.
Pour the dry ingredients into the wet, then use a rubber spatula to gently stir everything together, being careful not to over-mix. Optional: stir in the chocolate chips at this point.
Scoop a bit of dough into your hands (approx. 2 tbsp) and roll it into a ball, placing it directly onto the baking sheet. Repeat this process until all of the dough is gone (you may need to use 2 baking sheets). Then, use the palm of your hand to press the balls into cookies (note: the cookies won't expand when they bake, so make sure they're the size/shape you want them to be).
Bake the cookies for 10 minutes. Remove them from the oven and leave the cookies on the baking sheet for 2 minutes before carefully transferring them to a cooling rack. Wait until they cool slightly, then enjoy!
