Preheat the oven to 350 F. In a medium bowl, whisk together flour, pudding mix, salt, baking soda, and pumpkin pie spice. In a large bowl, mix together butter, pumpkin puree, and both sugars until fluffy.
Add in the egg and vanilla extract, and mix until smooth. Add in the flour mixture, mix until it is fully combined. Fold in the chocolate chips.
Use a cookie scoop to place the cookies onto a large ungreased baking sheet at least 2-inches apart. Bake for 10-12 minutes.
