The best& easiest coconut cake I have found is to just bake a plain white cake mix according to directions, let it cool & poke holes in it with a wooden spoon, then pour cocount milk over it. For icing I mix together 8 oz of softened cream cheese & 1 cup powered sugar then stir in 1 cup cool whip & spread over the cake & sprinkle with coconut. add cherries & green frosting leaves for color.
Here is a recipe I've made a few times and it's really easy and delicious.
It's made with a box mix, (just a warning in case you don't want to use a mix)
