Don’t worry to much about which candy you’re using to get to the exploding cake. If you can use blue and green, then do, but just make whatever matches you need to clear the cake and get rid of the chocolate as soon as you can for an open board.

You’ll notice the game isn’t very generous with the amount of green and blue it throws onto the board after that, but you’ll have plenty of opportunities to make combos, and these will get you the order you need eventually.
