01 - Preheat oven to 350°F. Line a baking sheet with parchment paper.
02 - In a large bowl, whisk together almond flour, shredded coconut, coconut flour, erythritol, and sea salt until evenly blended.
03 - In a separate bowl, cream the softened butter until light and fluffy. Beat in the egg, lime zest, lime juice, and vanilla extract until well combined.
04 - Add the dry ingredients to the wet mixture and stir until a cohesive dough forms.
05 - Roll tablespoon-sized portions of dough into balls and place on the prepared baking sheet. Flatten each ball gently with your palm or the bottom of a glass to about 1/2-inch thickness.
06 - Bake for 12-15 minutes, or until the edges are lightly golden.
07 - Allow cookies to cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely before serving.
