Gadget name: Vollrath Wear-Ever Cookie Sheet (Natural Finish)
It looks like: It has two raised edges for easy handling, plenty of space, and thick aluminum construction that resists warping and promotes even browning.
How we tested it: We baked three types of cookies (spritz, lemon, and lace) on both unlined and parchment paper–lined sheets, blending batches of dough and using the same oven so that the only variable was the cookie sheet being tested. Many dozen of cookies later, we learned we like thick sheets; thin sheets baked unevenly, ran hot, and tended to warp. Though a few baked well, most didn’t, and all warped to some extent. And in this testing, light or dark finishes mattered less than material: Aluminum sheets, we discovered, have better, more even heat transference than steel sheets.
How it actually works: Even without parchment, this sheet produced perfectly even cookies with matched tops and bottoms, released them easily, and didn’t warp even after numerous turns in the oven.
Good to know: You have to buy it at a restaurant supply store, or online—at least it’ll be delivered to your door.
My favorite part: It’s reasonably priced, and judging by performance, it’s worth every penny.
Overall: We think this is the world’s best cookie sheet, and it’s stood the test of time.
