- Preheat oven to 350ºF.
- Thoroughly mix together the coconut oil and coconut sugar until completely combined. Add the egg and vanilla and stir until combined.
- Add in the baking soda, salt, and cocoa powder and mix until smooth. Stir in the chocolate chunks. Use a cookie scoop to shape cookie dough balls. Sprinkle with flaky sea salt, if desired.
- If you want thick cookies, place dough in the freezer for 15 minutes before baking. You can also place the cookie dough in the fridge for up to 3 days before baking.
- Bake for about 10 minutes or until set around the edges but still gooey in the center. Let cool for 15 minutes on the baking sheet before transferring to a cooling rack to cool completely.
