In a large mixing bowl, whisk together almond flour, coconut flour, erythritol, cream of tartar, baking soda, and salt. In another bowl, cream the softened butter using a hand mixer, then add the egg and vanilla extract. Gradually combine the wet and dry ingredients until a smooth dough forms. Refrigerate the dough for 10 minutes to make it easier to handle.
Mix the erythritol and cinnamon in a small bowl to make the cinnamon-sugar coating. Roll 1 ½ tablespoon-sized portions of the dough into balls and coat each ball evenly in the cinnamon-sugar mixture.
Preheat your oven to 175°C and line a baking sheet with parchment paper. Place the coated dough balls on the baking sheet, spacing them about 2 inches apart. Gently press each ball to flatten slightly. Bake for 10-12 minutes or until the edges are lightly golden.
Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. Serve with coffee or tea for a delightful treat.
