Whisk together almond flour, gluten free 1-to-1 baking flour, cream of tartar, baking soda, ground cinnamon, pumpkin pie spice, and fine sea salt.
Beat butter and granulated sugar on medium speed for 2 minutes using a handheld electric or stand mixer until the mixture is light and fluffy. Add egg and vanilla extract and beat on medium speed until combined.
Scrape down the side of the bowl, then add the flour mixture and mix on low speed just until combined. The dough will be sticky.
Cover the dough with plastic wrap and refrigerate for 30 minutes.
Heat oven to 350°F (175°C).
To make the topping, mix sugar, cinnamon, and pumpkin pie spice in a small bowl. Scoop 2 tablespoons (35 grams) of dough and roll in the sugar topping mixture.
Line a light colored baking sheet with parchment paper. Place cookies 2 inches (5 cm) apart. Bake for 13 - 17 minutes until slightly golden brown.
