Preheat oven to 350 degrees and line two baking sheets with parchment paper.
In a medium-sized bowl, using a hand mixer, mix together coconut oil, eggs, and vanilla extract until well-combined.
To the same bowl, add monk fruit sweetener, cocoa powder, baking soda, salt, and cream of tartar.
Mix using hand mixer until fully incorporated.
One cup at a time, add almond flour and mix together with hand mixer.
Form dough into balls and lightly press down and place on prepared baking sheet (NOTE: cookies will spread when baking so be sure to place them about 2-3 inches apart.)
Add desired amount of sea salt to top of each cookie.
One baking sheet at a time, bake cookies until toothpick can be poked into center and comes out cleanly, about 15-18 minutes.
Remove from oven and allow to cool completely.
Once cooled, carefully peel the parchment paper away from the bottom of the cookie.
Serve and enjoy!
