Heat oven to 350°; prepare a sheet pan with parchment paper
In a small bowl, combine the coconut flour, almond flour, sweetener, pumpkin pie spice, salt, and baking soda with a fork. Mix in pumpkin, melted butter and vanilla until well combined and a dough forms. Mix in the chocolate chips.
Pack dough into 2 tablespoon (or 1-ounce) measure, and place on the prepared baking sheet. Use hands to flatten and form into evenly round cookies.
Bake for 10-12 minutes until edges are browned, watching closely in the last few minutes to prevent burning. Cool on the baking sheet for 30 minutes before moving- these cookies will be fragile until fully cooled. One cookie is one serving.
