Preheat the oven to 375°F. Line 2 large baking sheet with parchment paper.
In a medium bowl, whisk together the flour, spices, baking soda, and salt.
In a separate bowl, whisk oil, sugars, egg, and vanilla until creamy. Add pumpkin and mix until just combined.
Add the dry ingredients to the bowl with the wet mixture and mix until just combined. Fold in the oats, pecans, and chocolate chips. Cover with plastic wrap, then place the cookie dough in the refrigerator to chill for at least 1 hour.
Use a rounded 1 1/2-tablespoon cookie scoop to form a dough ball, then use your hands to roll it into a ball. Place each cookie dough ball on the parchment paper and flatten into a round disc.
Bake for 10-12 minutes.
While the cookies are baking, make the icing by combining the ingredients in a bowl until smooth. Cover until ready to use.
Remove the cookies from the oven and transfer them to a wire rack, and allow them to cool completely. When ready to serve, drizzle the maple cinnamon icing on top. Enjoy!
Notes
Best tip: Don't be surprised if you like these cookies even more the next day. Resting gives the oats time to absorb moisture from the pumpkin, making the cookies chewier and the flavors even better.Storage: After cooling, store your cookies in an airtight container for up to 3-4 days.To freeze, place the pumpkin cookies on a baking sheet and put them in the freezer. Once frozen, transfer them to an airtight container and store them for up to 2 months. When ready to enjoy, let them thaw at room temperature.
