Does anyone have any good BAKING recipes like muffins or cookies using Crystal Light drink mix?

I already have a couple of Crystal Light lemonade drink mix recipes for pies. I have about 20 4-packs of various flavors of Crystal Light I think might make nice muffin or cookie baking recipes for flavoring but not being a master baker or even a novice baker I have no idea how to mix it in to make some cookies or pies or cakes or muffins.
