In a medium bowl place oats, pumpkin, vanilla, honey and eggs and beat with a whisk until combined. Let sit at room temperature for at least 15 minutes to let the oats absorb some of the wet pumpkin ingredients.

Preheat oven to 350 degrees F.

In a large bowl combine flour, baking soda, salt, cinnamon and pumpkin pie spice. Set aside.

In the bowl of a stand mixer, add butter, brown sugar and granulated sugar and beat with a paddle to combine.

Add the oat and pumpkin mixture and beat to combine.

With mixer running on low, slowly add the flour mixture until combined.

Add chocolate chips and chopped walnuts and mix just a few turns to combine.

Line four cookie trays with parchment paper.

Using a 3 ounce scoop, scoop out dough and place eight per tray evenly spaced. I ran the rows front to back with two, then one, then two then one and then two.

Wet your hands and press each cookie down to ¾ of an inch thick. (If you are making a smaller 1 ½ ounce cookie, this step is not necessary)

Bake for nine minutes, rotate pan and bake for nine more. If making the smaller cookie, bake for 12 to 14 minutes, rotating half way through baking time.

Ovens are different so check as you get close to the end time. They are done when the bottoms are brown and the tops turn from a dark brown to a lighter brown and they have puffed up.

Let sit out of oven on the pan for ten more minutes, and then remove to a rack to cool.
