01 - Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper and set aside.
02 - In a large mixing bowl, combine the cashew butter, sweetener, egg, vanilla extract, and melted butter. Beat until smooth and well incorporated.
03 - In a separate bowl, whisk together the blanched almond flour, baking soda, and fine sea salt until evenly distributed.
04 - Add the dry ingredient mixture to the wet ingredients and stir until fully combined. If using, gently fold in the sugar-free dark chocolate chips.
05 - Scoop tablespoon-sized portions of dough onto the prepared baking sheet, spacing them approximately 2 inches apart. Flatten each cookie slightly using a fork or your fingertips.
06 - Bake for 10 to 12 minutes, or until the edges are golden brown and the centers are set.
07 - Allow the cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
