Anyone have any recipes for easy vegan dessserts? We're going to a cook-out this weekend, we've been asked to bring dessert, and at least one of the guests is vegan. Something that everyone will enjoy would be good.

By easy, I mean stuff that doesn't require unusual ingredients, or take lots of complicated steps. I can handle cocoa powder and soy milk, but I wouldn't know where to find vegan butter or dairy-free chocolate chips.

Thanks in advance for your help!
