Preheat oven to 350 degrees Fahrenheit. Combine all dry ingredients in a food processor and turn it on, drizzle the melted butter in until large pebbles form. Pour the mixture out onto a floured surface and roll to 1/4 inch thickness. Line a sheet pan with waxed paper, place the dough on the paper and refrigerate for at least 20 minutes. Bake for 10 minutes. Flip the dough, bake for another 5 to 10 minutes until golden. Don’t worry about breakage. When the dough cools, break it into small crumbs.
