01 - Preheat the oven to 350°F. Line a baking sheet with parchment paper.
02 - In a medium bowl, whisk together almond flour, coconut flour, baking powder, cinnamon, nutmeg, and salt until evenly distributed.
03 - In a large bowl, beat the softened butter and sweetener until creamy and light, approximately 2-3 minutes.
04 - Add the egg and vanilla extract to the butter mixture. Mix until fully incorporated and smooth.
05 - Gradually add the dry ingredients to the wet mixture, stirring until a soft, cohesive dough forms.
06 - In a small bowl, combine the topping erythritol and cinnamon. Mix well to evenly distribute cinnamon.
07 - Scoop tablespoon-sized portions of dough, roll into balls, and gently flatten onto the prepared baking sheet, spacing 2 inches apart.
08 - Sprinkle each cookie generously with the cinnamon-erythritol topping mixture.
09 - Bake for 10-12 minutes, or until the edges are lightly golden and set.
10 - Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
