Natural aluminum is the choice by professionals, and for good reason. This 14-inch by 13-inch pan turns out perfectly browned baked goods every single time. Three raised edges makes the pan easy to grasp; baked goods slide right off the smooth fourth edge. This cookie sheet won't warp or rust, so you'll enjoy it for years to come.
