Yield: 1 jar
Beat 1/3 cup butter (no substitutes) in a large mixing bowl with an electric mixer on medium speed for 30 seconds. Beat in 2 eggs. Stir in jar contents just until combined using a wooden spoon. Divide dough in half. Cover and chill until easy to handle, if necessary. Shape each portion of dough into a 9-inch loaf. Place loaves 4 inches apart on a lightly greased cookie sheet, flattening slightly until 2 inches wide. Bake at 375 degrees F for 25 to 30 minutes or until a wooden pick inserted near the center comes out clean. Cool loaves on the cookie sheet for 1 hour.
Cut each loaf diagonally into 1/2 inch thick slices using a serrated knife. Place slices, cut sides down on an ungreased cookie sheet. Bake at 325 degrees F for 8 minutes. Turn slices over; bake for 8 to 10 minutes more or until dry and crisp. Cool on wire rack.
