I I went through a phase of making soap cakes. I love piping soap. It is a really satisfying job when you start with your oils and end up with something that looks edible. I’m not actually very good at piping real cakes but with soap I don’t think I’m that bad. I put it all down to consistency, well that is my excuse anyway. My little ones love these. They are quite amused by the fact they are taking a cake into the bath.
