Baker's Delight

This Santoku-style kitchen knife is magically imbued with a specialized form of transmutation magic.

As an action, this knife can be used to transform any non-magical, non-living object into delicious chocolate cake with buttercream frosting simply by slicing it. The object can be no more than one cubic foot in total size. If the object is an item that contains other items, such as a box or a book, anything inside it becomes magically transformed into cake and/or frosting. Any magical items retain their form and are instead "baked" into the cake. 

Once the Baker's Delight is used in this manner, it functions as a mundane kitchen knife until dawn of the next day.
