Butter cracker recipes?

First to make the cracker and then again to dry it out.  

I think I would head in the direction of a butter or oil, milk and water pie pastry with yeast and some baking powder.  Slightly over work the pastry to make a dough and roll out thin. Prick with a fork and use a pastry wheel that makes perforated lines to divide the cracker after baking.  One bake might be enough as this is a low hydration dough.

Butter might be brushed on after the bake.
