The merchandiser of claim 3, wherein the frame comprises a wire rack configured and dimensioned to minimize interruption of airflow within the enclosure, and the spacing members comprise portions of the wire rack that extends toward the wall members to position the wire rack at a substantially central location in the enclosure so as to provide an air gap on each side of the frame.5. The merchandiser of claim 4, wherein one of the wall members includes a door for closing the opening, and the wire rack and spacing members are configured and dimensioned to allow positioning of the frame in the enclosure in at least a first position where the support surface(s) are angled downward to face the door and a second position where the support surface(s) face away from the door and are angled downward to face an optional second door opposite from the door.6. The merchandiser of claim 5, wherein each door is held in a closed position by magnetic force and includes a handle that is sufficiently large to be grasped by an insulating hot pad when the door is to be opened to gain access to the baked products in the enclosure.7. The merchandiser of claim 1, wherein the support member includes two or three support surfaces, and the enclosure comprises an insulation layer located beneath a bottom wall of the enclosure to inhibit or prevent heat loss from the enclosure.8. The merchandiser of claim 1, further comprising a mounting structure associated with the support member for mounting and positioning each support surface at a user accessible location and wherein each support surface is part of a tray that includes a lip extension to inhibit or prevent baked products from sliding off the support surface and is removably mounted upon the support member to facilitate removal for product placement thereon or cleaning thereof.9. The merchandiser of claim 1, wherein the enclosure further comprises one or more lights to illuminate a portion of the baked products in the enclosure in a manner that does not generate an amount of heat that substantially affects the controlled drying of baked products that are exposed to the light(s).10. The merchandiser of claim 1, wherein the heating system operates to maintain the interior space of the enclosure at a temperature of about 90° F. to about 180° F. and the baked product retains its organoleptic properties for a period of at least about 4 hours and is located sufficiently remote from the baked products and each support surface, such that direct contact or radiative heating of the products on each support surface by the heating system is at least substantially avoided.11. The merchandiser of claim 10, wherein the heating system comprises a heat source sufficient to heat the enclosure to provide controlled drying of the baked products therein, an air-moving device sufficient to circulate heat from the heat source through the enclosure, and a reflective member positioned near the air-moving device to inhibit or prevent overheating of the air-moving device from heat generated from the heat source.12. The merchandiser of claim 11, wherein the enclosure includes a front wall, a pair of side walls, and a rear wall with the front and rear walls being disposed between the side walls, and a housing structure that contains the heating system and that is disposed above each wall of the enclosure, so that the heating system is arranged to direct heated air downwardly into the enclosure and toward at least one wall of the enclosure at an angle of about 10 to 50° with respect to the wall.13. The merchandiser of claim 12, wherein the housing structure includes:an outlet configured and positioned to direct heated air into the enclosure; and an inlet to receive air from the enclosure that requires additional heat from the heat source to maintain the controlled drying of the previously baked dough products in the enclosure, wherein the outlet from the heating system corresponds to a portion of the space between a support surface and at least one wall sufficiently to control the substantially uniform airflow and the drying of the products in the enclosure. 14. The merchandiser of claim 13, wherein the outlet directs the heated air to enter the enclosure at a distance of about 0.125 to 1.5 inches from one of the walls to facilitate convective flow of the heated air between the support member and the enclosure walls.15. The merchandiser of claim 1, further comprising a temperature control system capable of maintaining the heated air at a temperature constant throughout the enclosure to within about 10° F. above or below a temperature that is selected based on the type of baked products to be placed in the merchandiser, wherein the enclosure comprises a heat-resistant thermoplastic component.16. The merchandiser of claim 15, wherein the temperature is maintained at a constant to within about 5° F. above or below the selected temperature.17.
