You don’t need to destroy a cake to get through this level, although it can help to open up the board. The bottom colour bomb can be detonated using striped candy or striped and wrapped combos, which leaves you with two to get.
If you open up the board by clearing the meringue column above the cake, then keep the chocolate down the bottom, you can make opportunities to get colour bombs without focusing on the cakes. If the candy falls the right way, use the cake to clear the board, but it isn’t essential.
