Preheat oven to 350°F and line 2 baking sheets with parchment paper.
In a medium bowl, combine flour, baking soda, and salt. Set aside.
In the bowl of a standing mixer with the paddle attachment or a handheld mixer, combine coconut oil and sugars, mixing until light and fluffy (1-2 minutes).
Add in the egg and vanilla extract, and beat until just combined (do not over-mix!).
Mix in the dry ingredients until a dough forms. Stir in the chocolate and mix until just combined.
Use a medium cookie scoop or spoon to make 1.5-2 tbsp sized balls and place them on the baking sheet around 3-4 inches apart.
Bake the cookies (one sheet at a time for even baking) for 8-11 minutes. Remove them from the oven when the edges look set. They will look under-baked in the middle! Remove from the oven and leave them on the baking sheet for 5 minutes, then transfer to a cooling rack to cool completely. Enjoy!

Notes
Measuring Flour: Always properly measure your flour using either a kitchen scale or by fluffing it up in the bag with a fork, then using a spoon to scoop the flour into the measuring cup and then use the back of a butterknife to level it off (the is the scoop and level method)Coconut Oil: If using coconut oil, note that the cookies will have a coconut flavor. The coconut oil can be used two ways:Room Temperature/Hardened Coconut Oil: The dough will be a little drier, but the cookies will still be great!Melted Coconut Oil: If the coconut oil is liquid - be sure it has cooled completely before combining with the other ingredients.Chocolate Chips: I recommend semisweet or dark chocolate chips, but you can use any kind you'd like. You can also use a chopped up chocolate bar or even white chocolate chips.Storage and Freezing:Store the cookies in an airtight container or ziploc bag at room temperature for 5-6 days.The baked cookies can be frozen in a freezer bag for up to 2 months. Thaw at room temperature when you're ready to eat them.
