No Bake Chocolate, Oatmeal and Coconut Cookies

We had friends coming over for dinner and I wanted to make a quick and easy dessert. I've been wanting to try no bake cookies for a long time but I was worried that my cookies may not set because I live in a humid climate...I was right. Unfortunately, I made them on a pretty rainy and humid day so they just wouldn't harden. I placed them in the refrigerator and it helped. We ate them quickly
