Notes

To ensure your cake is perfectly level for stacking or decorating, carefully trim the domed top using a serrated knife or for a more precise and effortless result, I highly recommend the Wilton Adjustable Cake Leveler (12 x 6.25-Inch), ideal for leveling and torting small cakes with even layers.
