Claim:
A baking tray comprising: a top sheet having a first top side, a first bottom side, and a first outer perimeter, the first top side including a first horizontal surface configured for supporting food for cooking in an oven; and a bottom sheet having a second top side, a second bottom side, and a second outer perimeter, the second bottom side including a second horizontal surface configured for supporting the baking tray upon an oven rack, wherein the bottom sheet is attached to the top sheet at an interface adjacent to the first outer perimeter and the second outer perimeter, the second horizontal surface comprises a plurality of spaced apart dimple portions separated on all sides by flat portions, the flat portions are defined by the second top side and the second bottom side and are spaced from the top sheet, each of the dimple portions are indented toward the top sheet, the dimple portions are substantially evenly distributed across the entirety of the second horizontal surface, such that the first horizontal surface is substantially evenly heated by the second horizontal surface when the baking tray is placed into a heated oven, and such that the first horizontal surface is heated more rapidly than that of a double-walled baking tray not having the substantially evenly distributed dimple portions, wherein each of the dimple portions is a spherical indentation of substantially uniform size and shape, are substantially evenly distributed across the entirety of the second horizontal surface, and are arranged in substantially straight rows and in substantially straight columns, and wherein the second horizontal surface has a surface area extending along perpendicular axes, and each of the dimple portions is spaced from every other adjacent one of the dimple portions by a distance no greater than about 10% of the shortest span of the surface area along either of the axes.
