Baked goods are often burned by exposure to heat radiation (infrared rays) from heating coils in an electric baking oven. The infrared rays strike the bottom surface of bakeware and heat the surface to the point of burning. The present invention provides a heat shield that protects the bakeware from infrared rays and burning. The present invention comprises a sheet disposed under a wire baking rack. The sheet blocks infrared rays and can be make of sheet metal. The sheet can be suspended by hooks, for example. In another aspect of the invention, the sheet is disposed on top of the wire baking rack. In this embodiment, the sheet has corrugations or bumps that provide only line contact or point contact with the bakeware. Hence, an insulating air layer is provided between the sheet and the bakeware.
