The frosting is Pillsbury Easy Frost chocolate frosting. It was easy for the kids to use it to stick the graham crackers together and to stick decorations in place.
We finished the haunted fun by reading In the Haunted House by Eve Bunting. This is a fun, slightly spooky (fun and silly, not scary) book about two children walking through a haunted house.
Another one of our favorite haunted house books is
Ten Timid Ghosts by Jennifer O'Connell. It really is a fun read. Ten timid ghosts live in a haunted house, but a witch moves in and wants them out. She plays tricks to scare them away, but in the end, the ghosts play their own trick. We love the rhymes and the countdown is a nice bonus.
