Is there anyone out there who doesn’t love the smell of freshly baked cookies? I, for one, love it: it’s the kind of smell that brings back childhood memories and makes me feel all warm and fuzzy inside.

Luckily, it also means I’m about to eat some freshly baked cookies, which is always an added bonus.

But the experience doesn’t come without a downside: once you take the cookies out of the oven and transfer them onto a plate, you’re left with crumbly, often burnt cookie sheets — and some of those brown patches can be nearly impossible to get off.

However, it doesn’t have to be such a chore. You just have to know how to do it right! In fact, you can clean cookie sheets with almost no effort at all. And chances are, you already have all these materials at home.

Scroll down to learn our methods and you’ll be on your way to clean cookie sheets in no time.

Why Do Cookie Sheets Warp And Burn?

You’ve probably noticed how some of your cookie sheets have warped out of their proper shape. The bottom isn’t completely flat anymore, and you don’t remember ever denting it. Well, that’s because you didn’t — your oven did.

According to, metal expands when exposed to high temperatures, and the thinner the material, the more affected by heat it will be. In other words, the thinner your cookie sheet is, the more it will warp in the oven over time.

Unfortunately, there isn’t much you can do about this, except to buy thicker cookie sheets next time. But hey, even if your cookie sheet is a little bent, the cookies will still come out delicious!

As for the burning, cookie sheets don’t get much oil on them when being used. It’s only normal for the metal to become discolored and a little burnt over time. To avoid this issue, you can either invest in a nonstick cookie sheet or place some parchment paper on top of it the next time you bake cookies.
