In a large mixing bowl, whisk together the egg, pumpkin puree, mashed banana, honey, melted coconut oil and vanilla extract.
In a separate large bowl, combine the oat flour, cinnamon, pumpkin pie spice, salt, and baking powder. Mix together and then pour into the bowl with the wet ingredients.
Pour wet ingredients into the bowl with the dry ingredients and mix until everything is combined and it has a cookie dough-like consistency.
Fold in the chocolate chips.
Using a heaping tablespoon or small cookie scoop, scoop the dough onto an ungreased cookie sheet, leaving room in between each cookie.
Place in the oven and bake for 15 minutes.
Remove from the oven and allow to cool for at least 20 minutes, then remove the cookies with a spatula and enjoy!
