Move the ingredients across the board until they are placed above one of their exits. This is definitely the hardest part of the level, as the middle columns are not very tall and the teleporters add to the confusion. There will be a few opportunities to move the ingredients across. Always be on the lookout for any possible switches.
When the ingredients are above their exits, concentrate on destroying the cake bombs. The cake bombs should only be destroyed when the ingredient is in the same column as that cake bomb. If only one ingredient has been placed above an exit so far, then concentrate on eliminating that cake bomb only, as it will bring down the ingredient immediately.
The two striped candies at the bottom of the board should be used to help with the cake bombs, although it is not vital.
Try moving both ingredients to the same side. This way, only one of the cake bombs has to be destroyed.
