I have a large order due this week and this is my SECOND time redoing these cookies and they still end up looking lik ewrinkled American cheese. I have tried dehydrating on 105 for 20 minutes, I have tried blasting them with the heat gun for a minute before dehydrating them, I can't figure out what the heck is going on! They are a 3x3 cookie and I just can't get them to dry flat. We have central air that has been on for days so there's little to no humidity in our home. Help please!
