The board is divided into four pieces, and one box is filled with some chocolate. If you don't find enough moves in that box to remove the chocolate, it will grow and fill the box prematurely, making the level almost impossible.
Bringing down 8 ingredients in 45 moves is not so easy, so this means you should bring down each ingredient in 5.7 moves.
If you are on phone, quit immediately the level if you can't make any move in the chocolate zone! On Facebook it will take you a life, but not on the phone. This will help prevent the chocolate from spreading. With the chocolate out of the way, the level should be much easier to pass.
The main obstacle is then the icing. Make as many horizontal striped candies on the left as you can and shoot them through the bottom, ideally combining them with wrapped candies to blast through more. Liquorice is a nuisance but basically harmless.
This is another primarily luck based level so most of it comes down to getting a good board.
