01 - Preheat oven to 350°F. Line a baking sheet with parchment paper and set aside.
02 - In a medium bowl, whisk together the almond flour, coconut flour, erythritol sweetener, baking powder, and sea salt until evenly blended.
03 - In a separate bowl, whisk the melted butter, egg, maple extract, and vanilla extract until smooth and well incorporated.
04 - Pour the wet mixture into the dry ingredients and stir with a spatula until a soft, cohesive dough forms.
05 - Gently fold the toasted chopped pecans into the dough, distributing them evenly throughout.
06 - Scoop tablespoon-sized portions of dough onto the prepared baking sheet, spacing them about 2 inches apart. Flatten each mound slightly using your fingers or the back of a spoon.
07 - Bake for 13 to 15 minutes, or until the edges are golden brown and the tops are set.
08 - Let the cookies cool completely on the baking sheet. They will firm up as they cool. Store in an airtight container at room temperature for up to 5 days.
