Easy Lemonade Lemon Cookie Recipe

I first came across a couple different versions of this recipe over the summer and made some with the kids.  We loved them!  They taste like summer, they are light and tangy and just the right amount of sweet. I think it's a little bit genius to make a lemon cookie using concentrated lemonade (the frozen kind) - you get all that great lemon flavor, but it's so quick and easy!  I use an organic lemonade concentrate, so it does not contain high fructose corn syrup.
