Preheat the oven to 350F, and line a baking tray with parchment paper, or a silicone mat. Set aside.

Whisk together the flour, cocoa powder, baking powder, baking soda, cornstarch, and salt. Set aside.

Whisk together the coconut oil and sugar until combined. Add the applesauce, and vanilla, and mix until combined.

Add the dry ingredients, and mix until just combined. Fold in the chocolate chips.

Roll the dough into large, 1.5 oz balls, and place onto the prepared baking tray. Bake for 12-16 minutes. Baking time will vary based on size of dough balls, oven, and altitude.

Allow to cool on the baking tray for 5 - 10 minutes before transferring to a wire rack to cool completely.

Pro-Tip! For that perfectly chewy cookie, smack the pan on the counter a few times to release air bubbles. If you like them flat, remove while baking at the 7-minute mark & smack the tray on the counter a few times to make them fall, then repeat the process once they out of the oven.
