Preheat the oven to 350 and line a baking sheet with parchment paper.
Combine the flour, baking soda, pumpkin pie spice, and salt in a small bowl. Set aside.
Gently press the pumpkin puree between a couple of paper towels to remove some of the moisture.
In a large bowl, cream your butter, light brown sugar, and cane sugar together until light and fluffy.
Add in the pumpkin puree, egg, and vanilla. Mix until combined.
Now, add in the dry ingredients and mix until just combined.
Fold in the rolled oats and chocolate chips until everything comes together.
Scoop the cookie dough onto a lined baking sheet using a cookie scoop. Don't overcrowd your cookie sheet. Bake the cookies for 10-12 minutes.
Transfer baked cookies to a wire cooling rack and let them cool completely. Enjoy!
