Ah, the chocolate chip cookie. While it is a simple, beloved dessert, it seems like everyone has an opinion on it. Even in my home, I’m constantly debating with my family about what constitutes the perfect chocolate chip cookie. Should it be crispy or chewy? Golden or underdone? Flat or pillowy? Plus, with so many different baking methods to choose from, it turns baking a simple chocolate chip cookie into a complex science experiment—one I happily dove into.

While the actual recipe of the cookie dough does matter for your cookies (we’re big fans of these 33+ cookie recipes), for this experiment, we wanted to narrow down the best baking method for cookies. Should you line your baking sheet with parchment paper or aluminum foil? Or should you just spray it down and leave it as is?

We did a deep dive into each baking method, evaluating the look and the taste of the finished cookies for each one, determining which method seems to reign supreme over all. Here’s what we found, and for more baking tips, here are the 23 Best Baking Tips of All Time.

The method I used for baking cookies

In order to have a proper comparison of all three baking methods, I set a few ground rules to ensure that the cookies remained on the same playing field for each baking method, to ensure that the comparison of each method was more about the baking versus the type or temperature of the cookie. Here are a few guidelines I set to get started:

  • For this cookie experiment, I used our classic Chocolate Chip Cookie Recipe.
  • From my experience, aging the dough gives the cookie an exceptionally rich flavor and helps the cookie to retain some structure. “Aging the dough” means letting it sit in the fridge anywhere between 30 minutes and up to a few days. For this experiment, I balled up my cookies into 2-tablespoon portions and aged them in the fridge for 24 hours.
  • When it was time to bake, I kept the cookies cold in the fridge before placing them on the baking sheet and into the oven as I tested each baking method. I did not leave the cookie dough out to ensure that the cookies all start at the same temperature.
  • For further temperature control, each cookie was placed on a completely cooled baking sheet before going into the oven.
  • I did not bake them all at the same time—each baking method had its own time in the oven to give it the same heat distribution as the others.
  • All of the cookies were baked in the middle of the oven on the same rack, baking at a preheated 375-degree oven.
  • Each cooking method had 10 minutes in the oven, then the cookies sat on the cookie sheet for 5 minutes after baking before I removed them to a cooling rack to do a taste test. While there is some debate around leaving cookies on the sheet pan so they don’t overbake, I find moving hot cookies right away could result in a hot, mushy cookie disaster. So to give them time to harden and retain some shape, I chose to bake my cookies with a smaller amount of time and give them time to set on the sheet pan.

So which baking method proved to be superior? Let’s dive in.

Parchment paper

Parchment paper generally seems to be a go-to for many at-home bakers, known for its non-stick qualities and ability to resist humidity. But does it really live up to the hype? Here was our thoughts on our parchment paper cookies:

Look: The cookies are pillowy and soft, but perfectly golden around the edges. The bottoms were not overcooked and also perfectly golden. The cookies did not spread out much, and are pretty fluffy and pillowy at the top even after letting them cool slightly. There don’t seem to be any undercooked spots along the top of the cookie.

Taste: Absolutely perfect. The inside is chewy and soft, and the outside provides that perfect crispy bite. The pillowy nature of the cookie gives it that soft, delectable texture. The centers are not underdone or overdone, making for an evenly baked cookie that melts in your mouth.

Aluminum foil

Now I admit, I had my suspicions about baking cookies on aluminum foil. Because it’s another type of metal, I figured it would bring extra heat to the pan and cause the cookies to overbake. Here’s how it turned out.

Look: These are definitely the most golden cookie out of all of these options. Originally I thought the cookie would be overdone because of the extra heat from the aluminum foil, yet the cookie’s golden bottom still matched the same as the parchment paper. The tops certainly have more golden flecks, and the cookie seems firm.

Taste: While the cookie seemed to be golden and perfect, the inside didn’t exactly cook to my liking. The bottom is certainly crispier than the others, while the top is still chewy and underdone—likely because the aluminum foil retained heat and caused the bottoms to bake more compared to the heat-resistant parchment This method works well for a person who loves the perfect mix of goldenly crispy outside and a chewy, underdone center. Yet it was clear when biting into the cookie that the bottom was cooked, while the top had yet to finish baking.
