Slightly lift the layer with the knife and insert a Cake Circle or a Cake Lifter to safely lift off the layer (if you have a turntable, you can use this same process to level your cake).
Hint: If you?re uncomfortable using a serrated knife or simply cannot get level results, consider trying a Cake Leveler. This tool has several notches so that the cutting wire can be adjusted to the proper height. The tool?s feet are always level with the surface, ensuring that your cuts are straight and uniform.
