Preheat your oven to 350 degrees.
In a medium mixing bowl, whisk together your dry ingredients (flour, salt, baking powder, baking soda)
In a separate, larger mixing bowl or stand mixer, cream together coconut milk, eggs, sourdough starter, olive oil, and sugar.
Add your dry ingredients to your olive oil mixture and combine well.
Pour batter into an oiled cake pan. I prefer to butter and oil my dish.
Bake at 350 for 45-50 minutes. (Prep icing while your cake is baking – see instructions below)
Once slightly cooled, gently remove from your cake pan to finish cooling on a wire rack or cooling rack.
Once your cake has completely cooled, move your cake to your cake stand and apply your icing with a piping bag.
