In a large bowl, mix together the oats, pastry flour, flaxseed, baking soda, pumpkin pie spice, cinnamon, cardamom, and salt.
In a separate bowl, mix together the bananas, pumpkin, and maple syrup. Slowly add it to the dry ingredients, stirring gently. It will be chunky because of the bananas.
Add in the chocolate chips.
Spoon or scoop the batter onto a prepared cookie sheet (with parchment paper).
Bake for 14-17 minutes until lightly browned. The cookies will be soft and delicious!
