Why you shouldn’t bake cookies on foil
Plenty of people use aluminum foil in the oven for all kinds of things.
Covering roast turkeys, as a base for roast vegetables, and even sometimes in baking.
The idea is that it’s not going to smoke or start a fire like wax paper (never put wax paper in the oven), and so it should be perfectly fine to use as a liner for your tray or baking sheet.
But aluminum foil reflects heat, which means it’s going to basically send heat straight into the bottom of your cookies.
And sure, we want to cook the bottom of our cookies, but you don’t need extra help.
You run the risk of burnt cookies and particularly burning the bottoms of your cookies, and then you’d have to check out our guide on how to fix burnt cookies and it’s just not pretty.
What to do instead
So you’re not supposed to use foil to bake your cookies. What should you do instead?
The best substitute is either baking paper (parchment paper) or a silicone baking mat.
These are both going to help your cookies bake evenly without causing the bottoms to overbake.
The materials used in both helps keep the heat even.
If you don’t have parchment paper or a silicone baking mat, you would still be better off using a regular baking sheet with nothing on it rather than covering it in foil.
But my friend said I can bake cookies on tin foil!
Maybe your mom always baked her cookies on foil or your friend does it all of the time.
There are opposing viewpoints with people who say that they use foil and their cookies turn out fine.
While it is possible, it’s not worth the risk if you’re trying to get your cookies right the first time.
If you do have time to experiment, then, sure, use foil and try turning down the temperature in your oven or move the baking sheet further away from the heat source to compensate.
But there’s no getting around the science of it.
Foil is a conductor of heat, which means that the bottom of your cookies are going to get a lot more heat than the other parts of the cookie and lead to uneven baking and possible burning.
It may turn out okay for you, but now you’ll know the reasons why if it doesn’t!
