Make as many wrapped candies as possible. Collect colour bombs whenever an opportunity arrives. By using the colour bombs that you created, you can reduce the colours on the board and make it easier to collect the remaining wrapped candies.
This level used to have a different order in that it required 2 colour bomb + wrapped candy combinations. Moreover, the chocolate spawner was in the middle, and 4-layer icing were in place of the 3-layer icing.
