Copyrighted baking and soap making molds

The copyright in the molds extends to the molds.  You could not copy and sell the molds themselves.  However, the molds are sold with the intention that people use them to create articles.  The rights of the copyright holder of the mold design do not extend to the articles created with the mold. That said, as I advise all parties who base a business on intellectual property, you should obtain a private opinion upon which you can rely that is specific to your facts from an intellectual property attorney in your jurisdiction.  A short, relatively inexpensive consultation should suffice.  Obtain a quote for the servife in advance.
