Mix together all of the ingredients EXCEPT the sea salt in a medium bowl until completely smooth. A couple of times I’ve needed to warm the mixture up just a bit to get the coconut oil to smoothly mix in. If you find you need to do this, create a bain marie by heating a pot of water to a simmer. Reduce the heat. Place the mixture into a metal mixing bowl and place the bowl over the hot water. Gently stir occasionally until it's completely melted.

Line a baking pan with parchment paper, folding it into the corners. Scrape the batter into the pan and smooth with a spatula.

Cover with plastic wrap and place in the refrigerator for 2 hours or until completely hardened. Cut into squares, and sprinkle with sea salt before serving.
