Preheat your oven to 350°F (175°C).
Line a baking sheet with parchment paper or a silicone baking mat.
In a large mixing bowl, whisk together the white whole wheat flour, cornstarch, baking soda, baking powder, and salt until well combined.
In another bowl, mix the granulated sweetener with the unsweetened applesauce, melted coconut oil, and vanilla extract until smooth.
Pour the wet mixture into the dry ingredients, and stir until just combined. Avoid overmixing.
Gently fold in the chocolate chips until evenly distributed.
Scoop rounded balls of dough onto the prepared baking sheet, leaving space between each cookie.
Bake for 10-12 minutes, or until the edges are lightly golden.
Allow cookies to cool on the baking sheet for about 5 minutes before transferring them to a cooling rack.
