Preheat oven to 350 degrees and line baking sheet with silpat mat. (The mat is optional, see notes below)
Scrape the pumpkin pie filling from the crust into a mixing bowl.
Mix in both chocolate chips and oatmeal. Add tablespoons of flour as needed.
Form dough into 1 inch balls and put onto baking sheet. Press down with fork and flatten dough. Bake for 9 minutes and leave on pan until cool. Enjoy!
Notes
Ingredients will fluctuate based on how much pumpkin pie you have leftover. For reference I had about 3/4 of the pie left.
I found adding 2 tablespoons of flour helped me form the cookies.
The first batch I made, I used a little bit too much oatmeal and didn't love the texture.
Pressing cookies down with the fork is key, the pumpkin pie is already cooked and doesn't spread. Unless you want pumpkin balls!
I found using the silpat left my cookies very soft moist and delicious! However, on the second batch, I tried it without the slip mat and it did stick to the baking sheet but did have a little more of the cookie consistency I was looking for.
