Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large mixing bowl, combine the granulated sugar, brown sugar, and melted coconut oil or butter. Mix well until creamy.
Add the egg, apple sauce, and vanilla extract to the sugar mixture. Whisk until thoroughly combined.
In a separate bowl, whisk together the all-purpose flour, baking soda, and kosher salt.
Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix!
Gently fold in the sugar-free chocolate chips, ensuring they are evenly distributed throughout the dough.
Using a cookie scoop or tablespoon, drop the dough onto the prepared baking sheet, leaving some space between each cookie.
Sprinkle a pinch of sea salt on top of each cookie for that extra burst of flavor.
Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden. The centers may look slightly underbaked; this is perfect for a chewy texture!
Allow the cookies to cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely.
