A baking tray includes a top sheet and a bottom sheet. The top sheet has a first top side, a first bottom side, and a first outer perimeter. The first top side includes a first horizontal surface configured for supporting food for cooking in an oven. The bottom sheet has a second top side, a second bottom side, and a second outer perimeter. The second bottom side includes a second horizontal surface configured for supporting the baking tray upon an oven rack. 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 dimple portions and flat portions. The flat portions separate the dimple portions and are spaced from the top sheet. Each of the dimple portions is indented toward the top sheet.

What is claimed is: 1. 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. 2. The baking tray of claim 1 wherein each of the flat portions of the bottom sheet are substantially parallel with corresponding portions of the top sheet. 3. The baking tray of claim 1 wherein at least some of the dimple portions contact the top sheet. 4. The baking tray of claim 3 wherein each of the dimple portions contacts the top sheet. 5. The baking tray of claim 1 wherein none of the dimple portions contacts the top sheet. 6. The baking tray of claim 1 wherein at least about 5% of the surface area of the second horizontal surface is provided by the dimple portions. 7. The baking tray of claim 6 wherein at least about 10% of the surface area of the second horizontal surface is provided by the dimple portions. 8. The baking tray of claim 7 wherein at least about 15% of the surface area of the second horizontal surface is provided by the dimple portions. 9. The baking tray of claim 1 comprising at least thirty-two of the dimple portions. 10. The baking tray of claim 9 comprising at least sixty-four of the dimple portions arranged into at least eight rows and at least eight columns. 11. The baking tray of claim 1 wherein each of the dimple portions has substantially the same diameter and is spaced from every other adjacent one of the dimple portions by a distance no greater than about five times the diameter. 12. 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 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, and each of the dimple portions has substantially the same diameter and is spaced from every other adjacent one of the dimple portions by a distance no greater than about five times the diameter, 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 at least about 10% of the surface area of the second horizontal surface is provided by the dimple portions; 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 the axes. 13. The baking tray of claim 12 wherein at least about 15% of the surface area of the second horizontal surface is provided by the dimple portions. 14. The baking tray of claim 12 comprising at least sixty-four of the dimple portions arranged into at least eight rows and at least eight columns. 15. 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 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.
