A cake decorating assembly, kit, and method of use comprising a mount which includes a longitudinally extending member. The assembly further comprises a top blade subassembly, a lateral blade subassembly, a gauge subassembly, and a cutting subassembly, all of which may be removably attached to the longitudinally extending member. All of the top blade subassembly, the lateral blade subassembly, the gauge subassembly, and the cutting subassembly may be vertically adjusted relative to the longitudinally extending member, while the gauge subassembly may also be horizontally adjusted relative to the longitudinally extending member. The cake decorating assembly provides for, e.g., the efficient decoration of a cake and further assists, e.g., in the even distribution of frosting on a cake.
