A merchandising pretzel baking oven has a vertical casing defined by a lower rigid wall portion and an upper transparent wall display case with a horizontal partition wall therebetween. The lower portion has a baking chamber constituted by upper and lower sections of truncated rectangular base pyramidal shape horizontally fixed therein with timer controlled electrical heating rods mounted at the closed top wall of the upper section and at the open bottom wall of the lower chamber. A baking tray adapted to contain frozen pretzels is slidably supported by the lower portion and is movable into and from the oven chamber horizontally intermediate the sections thereof through one wall of the lower portion with a cleanout tray, arranged below the oven chamber, being also slidable in such wall. The other walls of the lower portion have combined heat insulating and illuminated advertising display panels provided on their outer faces.
