Combine all ingredients in a bowl, until well combined and a dough is formed.
Place a sheet of parchment paper on a cookie sheet, place the dough in the center, top with another sheet of parchment paper.
Roll until very thin and remove the top piece of parchment paper. Make squares with a pizza cutter.
Bake for 50 minutes at 250°F, then check every couple minutes until they have just begun to brown.
Remove from oven and let cool completely, before breaking into the pre-scored squares.
