Preheat your oven to 350 degrees. Grease a 9x9 square pan with coconut oil.

Melt 1/4 cup of coconut oil and let it cool while preparing your other ingredients.

Beat eggs, coconut milk, xylitol, stevia, and key lime juice until well combined.

Mix baking powder, salt, lime zest, coconut flour, and coconut flakes together in a separate bowl.

Beat the two mixtures together and then add the coconut oil.

Pour the cake batter in the 9x9 pan and bake at 350 degrees for 35 - 40 minutes.

Allow the cake to thoroughly cool before making icing.

Melt coconut oil and xylitol over medium heat.

When xylitol is melted into the coconut oil, remove from heat and add lime zest, vanilla, and salt.

Let cool in the refrigerator for just a few minutes. When the mixture begins to just slightly whiten, pull it from the refrigerator and pour into your blender and whip. The goal is to whip air into the icing.

Pour icing on your cake and top with toasted coconut flakes.
