On the odd occasion when you do not have any parchment paper available you may wonder what you can use instead of parchment paper for your cookie baking antics. While parchment paper works really well when it comes to cookie baking, the main properties of parchment paper that are used for this exact process are the anti-sticking properties.
This is why you can use anything really as long as it does not stick. You could use aluminum foil instead of parchment paper for your cookie baking, although we would recommend you grease the foil first to prevent any of your cookies getting stuck to it. The best solution in this instance is to simply grease the baking tray to prevent the cookies from sticking.
