Add all of the cake ingredients to a food proc, and processor until a cake-like consistency is reached. It will be sticky, but that is what you want. Place it into a bowl and set into the fridge.
Add all of the frosting ingredients to the high speed blender and process until smooth and creamy. Start with ¾ cup of coconut water and add as needed for it to become smooth.
(See Note)* Press the first layer into the dish/tray you are using for your cake, press it in, then pour your first layer of frosting over it. Continue until you have filled your pan/dish, then add your toppings of choice. Place into the freezer to set before serving, about 1-2 hours.
To serve, remove from the freezer and allow it to sit for 5-10 mins for a softer cake-like consistency, or enjoy it as is! Enjoy!
