Preheat oven to 350 degrees F.
Grease a 9-inch spring foam cake pan and line the bottom with parchment paper.
In a large mixing bowl, whisk together almond flour, cassava flour, coconut sugar, cocoa powder, baking soda, and sea salt.
In a separate bowl, whisk together eggs, coconut milk, water, ghee, apple cider vinegar, and vanilla extract.
Pour wet ingredients to dry ingredients and stir together until a batter forms.
Pour the batter into the prepared cake pan and flatten out the top with a spatula.
Bake for 45-48 minutes, until a toothpick inserted in the center comes out clean.
Allow the cake to cool completely.
