Preheat oven to 350F. Line a baking sheet with parchment paper.
In a medium mixing bowl, mix the ground flax seeds with 2 tablespoons of water. Let sit while you prepare the rest of the recipe.
In a medium mixing bowl, combine your oats, almond flour, sugar, tapioca flour, baking soda, salt, chocolate chips and pumpkin spice.
Once the flax egg has thickened, stir in the maple syrup, pumpkin puree, coconut oil and vanilla to the same bowl. Stir to combine. The coconut oil may not mix smoothly, it's okay if you have some small pieces.
Add the wet mixture to the dry mixture. Stir to combine.
Form 8 cookies and place on the parchment paper, leaving some distance between each cookie. They do spread a little. Form a little mound with each cookie, pressing them down only a bit. This limits the spread and leads to thicker, chewier cookies. See photos for guidance.
Bake for 15 minutes. Let them cool for at least 5-10 minutes. They will be delicate when warm.
