I know, I know... these cookies are a bit, juvenile. But hey, in my defense, they were originally baked for a bunch of 3rd graders. Who, by the way, thought that a dirty diaper cookie was hilarious.

Basically, you just cut triangle-shaped sugar cookies, fold a miniature candy bar inside, and bake.
Perfect for any baby shower. (I just hope your guests bring a sense a humor with them to the party.)
