Preheat the oven to 350 degrees F and line 2 sheet pans with parchment paper.
Whisk together the eggs, vanilla extract, melted coconut oil and coconut sugar in a large bowl.
Add the almond flour, coconut flour, baking soda and salt, then mix together until fully incorporated.
Mix in the chocolate until evenly distributed.
Scoop out large rounded tablespoons of dough on to the prepared sheet pans, then use your fingers to press down and flatten into a cookie shape.
Sprinkle each cookie with sea salt.
Bake for about 12 minutes or until browned and a bit crisp around the edges. Let cool just a bit before eating.
Cookies will keep in an airtight container at room temperature for up to a week.
