Add the coconut oil and both sugars to a large mixing bowl or bowl of a stand mixer and beat together for 1 minute.
Add in the egg and vanilla and cream together until smooth.
Add in the dry ingredients aside from the chocolate, making sure to spoon and level the flour.
Mix until smooth.
Fold in the chocolate chips. Use a 2 tablespoon scoop and scoop into balls.
Place on a baking sheet lined with parchment paper (keeping each cookie a few inches apart. I usually use 2 trays) and add to the fridge for 1 hour.
Toward the end of the hour, preheat the oven to 350 Fahrenheit.
Bake for 11-15 minutes (I usually do 13, but all ovens are different) or until the edges are just golden brown.
They will continue to firm up as they cool, so take them out a bit early if you like soft centers.
Let cool completely, then sprinkle with salt flakes and enjoy!
