Can I substitute wax paper for parchment paper?
In most cases, wax paper should not be substituted for parchment. This is because parchment can withstand oven temperatures up to about 425 degrees without burning, while wax paper will smoke when subjected directly to oven heat. So wax paper will do just fine for lining a cake pan bottom, but not as a lining on a cookie sheet. Wax paper will smoke even in a moderately hot oven.
