To have an easier time, try to take the coconut wheels out of the marmalade. Then, use one of them to roll upwards, creating a line of striped candies to hit the coconut wheel at the right. Afterwards, roll it to the left side to reduce the icing.
Take care of the bombs. They only allow 10 moves to destroy and constantly drop down in every other move, so get rid of them as soon as possible.
It is possible to combine a coconut wheel with a special candy, like a striped candy or a colour bomb, to blast the icing with even more impact.
Concentrate effort on destroying icings rather than bringing ingredients down, as they will fall down inevitably from holes in the board and the matches you make.
