I am trying to find some books that I read when I was a kid for my two young sons. One book was about a boy who is making something for his mother (it turns out to be a cake I think, but I remember he makes a mess and throws all kinds of stuff in the bowl) and the line that he keeps repeating to his mother when she wants to know what he is doing is "you will see and understand that I am making something grand." I sure hope someone can help me with this.
