These days everyone's so health conscious but when you think of cakes, the cream, the layers, yummmmm. You can't just resist a cake that easily so why not try something different. So here is a DIY cake made out of a watermelon. Yup, you read it right that is a watermelon cake with very less cream which makes it very healthy and less on the calorie. Wonder what they will bring next, a spinach burger probably.
