01 - Preheat the oven to 350°F. Line a baking sheet with parchment paper.
02 - In a medium bowl, whisk together almond flour, cocoa powder, coconut flour, baking powder, salt, cinnamon, and nutmeg.
03 - In a large bowl, beat softened butter and erythritol until light and fluffy. Add eggs one at a time, then stir in vanilla extract.
04 - Gradually add the dry ingredient mixture to the wet ingredients, stirring until just combined. Fold in chocolate chips.
05 - Scoop tablespoon-sized portions of dough onto the prepared baking sheet, spacing them about 2 inches apart. Gently flatten each with fingers or the back of a spoon.
06 - Optionally, sprinkle crushed peppermint or chopped nuts atop the cookies before baking.
07 - Bake for 10 to 12 minutes, until edges are set but centers remain soft.
08 - Let cookies cool on the pan for 5 minutes, then transfer to a wire rack to cool completely.
