Try to make as many special candies as you can. The colour bomb + striped candy combination is the most helpful to get rid of the single icing at the top. Keep an eye on the candy bombs dropping down for only 9 moves, making the level very hard. Try to clear the jelly on the top first and then clear the edges of the board.
If no combination is available, try to make as many striped candies as you can - sometimes the conveyor belt produces it by cascading.
