In a large bowl, mix the wet ingredients together - egg (room temperature), butter (room temperature), and almond butter.
In a separate bowl, combine coconut flour, almond flour, baking soda, and cinnamon. Gently fold wet ingredients into the dry ingredients.
Cover dough and place in the freezer for 20 - 30 minutes.
In a small dish, prepare the cinnamon-sugar coating.
Scoop cookie dough into equal-sized dough balls. Roll dough balls around in cinnamon sugar, covering the entire cookie dough ball. Press the cookie dough balls down with the palm of your hand ***
Bake 10 - 11 minutes. Let it cool for a couple of minutes then move it onto a cooling rack.
Notes
*** The cookies will not expand a ton, so press them a little bit (just enough to have some thick snickerdoodles)
