Abstract: An apparatus and method for treating baked goods, such as bagels, is disclosed. An outer ring including downwardly projecting pins is secured to the cut surface of a previously sliced bagel half. A cutting disc having an upwardly projecting handle and downwardly projecting cutting blades is rotatable within the outer ring, which out ring serves as a guide and as a bearing. By turning the cutting disc while maintaining the bagel and the outer ring stationary, a circular trough will be cut in the dough of the bagel half by the cutting blades. In an antomatic version of the apparatus, a flat, upwardly projecting screw is mounted in a base plate and a bagel half is secured by base plate mounted pins about the flat screw. A cutting disc is provided with a slot to receive the flat screw in a manner to automatically rotate the cutting disc relative to the bagel when the cutting disc is axially moved toward the base plate.
