Can i use aluminium foil as a replacement for wax paper for baking cookies?
Yes you can. Or, as the other people said, you can bake them on the sheet pan without foil. However, the foil makes clean up a lot easier. Another option would be to buy a silicon baking mat, called a “silpat mat”. Just lay the mat on a sheet pan and bake your cookies on the mat. These mats are great and you don’t need to oil them. They are reusable, cheap and make clean up a snap…. the cookies never stick to them. They are a good option for parchment paper or wax paper…. and they have multiple uses. (By the way, I’ve used foil many times to bake cookies and it works great.
