The main problem here is the chocolate in the bottom right. It has one space to port the chocolate over to the left hand column and really can get in the way, so keep your eye on it and clear it when you can. If you can make a vertical striped candy and drop it through the blue teleporter at the bottom of the left side or make it up on the top right, you can rip through a chunk of chocolate. If you pull off a horizontal candy and run it through the second to last row the chocolate will be contained to that area and will NOT advance.

A striped/wrapped combo will clear much of the chocolate, but it isn’t necessary to beat the level. Keep the chocolate as contained as possible, and make as many striped as you can. They will travel through the teleports (as long as the chocolate doesn’t get them) and you can use them to shoot holes in the chocolate.
