This is the link to the highest rated cookie recipe using chocolate chips on recipezaar - http://www.recipezaar.com/48532. I've never had these so I cannot vouch for them myself, but there are currently 84 ratings on this recipe that you can read thru to see if it's something you might like to try.
Here is the link to the second highest rated cookie recipe using chocolate chips. It's actually for a chocolate chip cookie and it uses vanilaa pudding in the recipe which sounds interesting - http://www.recipezaar.com/20408.
Here's another one that sounds interesting. Read thru some of the reviews and you'll see that one person used an orange cake mix for their batch and it sounds like it was a real winner! http://www.recipezaar.com/15559
Here are a couple more highly rated ones just for good measure:

Again, I've not tried any of these, but recipezaar is where I go anytime I need to try something new. My best advice is to read as many of the reviews as you can. They can reveal some very helpful hints!!
Good luck! Let us know how you do in the competition!
