This baking set combines one fluted round cutter with six interchangeable center inserts for preparing decorative sandwich cookies. The main cutter measures approximately 2.25 x 2.25 x 1.6 in (6.3 x 6.3 x 4 cm), while the inserts create different cut-out designs in the upper cookie layer. Use the cutter without an insert for the solid bases, then fit a chosen insert when cutting the matching tops. Once baked and cooled, the paired cookies can be assembled around a filling that remains visible through the decorative centre.
