Preheat the oven to 350 degrees F. Line two baking sheets with parchment paper and set aside.
In a medium-sized bowl, combine the pumpkin, sugar, oil, egg, and vanilla extract. Mix until well combined.
In a separate bowl, whisk together the flour, baking powder, baking soda, cinnamon, and salt.
Little by little, add the dry ingredients to the wet. Mix until the flour has just disappeared.
Add the chocolate chips and stir to distribute them evenly throughout the dough.
Using a cookie scoop, drop cookie dough by the tablespoonful onto the prepared cookie sheets. Bake for 10-12 minutes, or until the cookies are lightly browned and firm.
Allow them to cool on the baking sheets for 5 minutes before transferring to a wire rack to finish cooling completely.
