Preheat the oven to 180C/350F. Line a large tray or cookie sheet with parchment paper and set aside.
In a large mixing bowl, combine your cashew butter, granulated sweetener, egg, baking soda, and mix until combined. Fold in your chocolate chips. Cover the bowl and refrigerate for at least 30 minutes.
Remove the dough from the refrigerator. Using your hands, form 12 small balls of cookie dough. Place each ball on the lined tray and press each one into a thick cookie shape. Bake for 10-12 minutes, or until the edges just start to brown.
Remove from the oven and allow to cool on the tray completely.
