Remove a part of image on mouse click ?

I am making a cake pop party type of game. And need to eat the saved textures piece by piece.
just want to know how to implement this feature. clicking on the image removes a part of image where the mouse clicked. I am stuck and any direction in this regard would be helpul.

thanks in advance.

clicking on the image removes a part of image where the mouse clicked.- this is what u want to do?

well u need to picture ur cake as a puzzle.all the pieces assembled together. U will have to create separate bite pieces and place them together so that it looks like a whole cake… then if the piece is clicked, destroy it…
