I wouldn't. Instead I'd grease the baking sheets.
Your house will smell like burning candles, and your cookies will taste like them.
Parchment has a silicone-based coating that will withstand the high temperatures of an oven. Wax paper is, not surprisingly, coated in a wax. The wax can, and will, transfer to your food. The other concern with wax paper is that there is a good chance it will catch fire in your oven.
Agreed. Wax paper isnt intended for that kind of high heat exposure. That said, I do us it to line cake pans when the paper will be covered completely by batter and not directly exposed to the oven's heat.
DO NOT USE waxpaper as parchment paper. The coating will melt and ruin your food!
No! Wax paper is not oven safe and will smoke and burn in your oven.
No way! I did a silly mistake few weeks ago..by baking potato puffs onto wax paper because i didn't have parchment paper and didn't wish to grease it with cooking spray or butter..never is the answer..
