The problem created here is all the ingredients come down the middle column and you have chocolate fans right at the bottom of it making this level a heck of a lot more difficult. You are given 2 horizontal striped candies to help you out, but you need to use the 4 colors here to make more horizontal striped candies to aid the descent of the ingredients. Try to zap a piece that will match the pieces around it once it is gone.

The best combo here is the color bomb/striped combo, but striped/wrapped combos will clear those candies in the center column as well. Until you can make either of those, keep making horizontally striped candy matches to keep the chocolate at bay and bring the ingredients down.
