I've tried this cake two different ways and both were delicious. White cake mix with coconut-pineapple water. I frosted it with 2 cups cool whip and lightly sprinkled coconut on top. Then I also tried chocolate cake mix with black cherry water. Mixed 1 tsp. cocoa and 1 tsp. cinnamon into 2 cups cool whip to frost. You could use sugar free cool whip. Very good.
