Here's the final version......
and this is how is was made!
I just wanted to make the topping of the cupcake a rainbow cake so the tip (the cherry on the cake) needed less batter than the next layer and that layer needed less than the layer after it and so forth till the cake was complete.
and once the cake was cut, the surprise was revealed!
