Wrap your Graham Cracker dough in plastic wrap, or cover your mixing bowl to keep it from drying out, and place it in the fridge for a few hours or a few days.
Preheat your oven to 325oF. Place the dough onto a piece of parchment paper (18" x 13") and lightly flour the dough. Roll out to about a quarter inch thick, the dough should fit approximately onto a cookie sheet.
Using a sharp knife or pastry cutter, cut your dough into squares; use a fork to poke holes into each square. Bake for 15-20 minutes, until the top of the dough begins to turn a darkened golden. Remove the crackers from the oven, allow them to rest on the pan an additional 5 minutes, then transfer them to a cooling rack.
