01 - Preheat the oven to 350°F. Line a baking sheet with parchment paper.
02 - In a medium bowl, whisk together almond flour, baking powder, and salt until evenly distributed.
03 - In a large mixing bowl, beat the softened butter and erythritol until light and fluffy, approximately 2 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 ingredients, mixing on low speed until a cohesive dough forms.
06 - Fold in the chopped pecans by hand until evenly distributed throughout the dough.
07 - Scoop approximately 1 tablespoon of dough per cookie onto the prepared baking sheet, spacing 2 inches apart. Flatten each cookie slightly with your fingers or the back of a spoon.
08 - Bake for 13 to 15 minutes, or until edges are golden brown and centers are set.
09 - Allow the cookies to cool completely on the baking sheet. The cookies will firm up as they cool.
