Preheat oven to 350°F. Line a baking sheet with a silicone mat or parchment paper, set aside.
In a mixing bowl, stir together the almond flour, coconut flour, baking soda, cream of tartar, salt, and cinnamon. Add the coconut oil, maple syrup, and vanilla extract and stir with a spatula or wooden spoon until thoroughly combined.
In a separate small bowl, make your cinnamon sugar by stirring together the cinnamon and coconut sugar.
Using a cookie scoop or tablespoon, measure out about 1 heaping tablespoon of dough and roll into a ball. Roll each cookie dough ball into the cinnamon sugar mixture.
Place on prepared baking sheet about 2 inches apart. Flatten cookies with the flat bottom of a glass, about 1/4 inch thick. They do NOT spread, so make them as thin as you like them. Bake for about 8-9 minutes, no longer than that! You want them to be soft when they come out because they firm up as they cool. So DO NOT OVERBAKE…trust me!!!
Let cool for 10 minutes and then transfer to a cooling rack to cool completely. Store leftovers (if any) in an airtight container on the counter.
Enjoy!
