Start by making regular matches, perhaps adjacent to the five-layered frosting. You can also create some colour bombs if possible. During these few moves, the striped and wrapped candies will spawn from the cannons and move to the bottom-right section of the board via the conveyor belt.
The special candies will be adjacent to each other after reaching the bottom-right corner. However, wait a couple more moves - the special candies will be brought back up to the top-left section (They will still be adjacent to each other). It's highly recommended that you combine them in the top-left section instead of the bottom-right. Otherwise, the blast will be partially blocked due to the liquorice swirls.
The blast will take at least one layer off the five-layered frosting. It may also set off the special candies you set up in your first few moves.
After that, keep creating more special candies. A colour bomb + wrapped candy combination is highly recommended due to the setup of the five-layered frosting. It is the most efficient way of bringing the ingredients to the exits.
