While it is preheating, take the oven tray, place an nonstick pan. Grease the pan and put about 1-inch mounds. Place the tray in the oven and put the timer for 5 hours.

Check on them at about 4 hours (ovens vary). In my oven, they are done in about 4-5 hours.

When it is light brown on the top and they are flat; you can flip them easily and let them dry for another hour. They will just slide out easily.

Then put them in airtight boxes.
