I found a gingerbread house-like kit at a store the other day that was a cookie castle kit for Disney Princesses. We built it together as a family & the girls LOVED it! It looks great, but it tastes awful! ;) The girls don't seem to notice though!
Now I'm trying to think of a way to get rid of most of it before they consume too much of it ;) It was definitely fun, though I think next time I'll stick with gingerbread!
