Soap Piping Won't Stick

by Liz

I made 2 soap cakes yesterday. I cut them today. They had set up beautifully and look spectacular but as I was cutting some of the piping lifted. It didn't shatter or anything horrible like that, it just lifted clean off the top of the cake.

I spritzed the top with isopropyl alcohol before piping and there wasn't too much time delay between the cake making and piping, probably about 1/2 an hour.

The same soap recipe was used to pipe as what I used for the cake.

My batters were made at the same temp, just the time delay was involved.

Because it had TD in it I did what I had been told to do and popped it in the fridge for a couple of hours then back inside covered and left overnight on the bench.

They look gorgeous and smell divine, just a bit of the top has separated from the main body.

What have I done wrong for this to happen??

I don't want to attempt another one till I understand what I did wrong.

Is there anyway of sticking the bit back on?

I did joke with my hubby that I would use the hot glue gun or araldite but I won't so don't panic!

Thanks for any help you can give an guide me on the way to making even better soap cakes.



I'm afraid that I haven't played around with soap frosting!

You would think that after all these years I would have but for some reason I've not done so.

Because of this I don't really know what you could do to fix it or to avoid the soap from pulling off.

I did a bit of searching but couldn't find anything other than making the frosting and nothing about stopping it from lifting off the cake.

I do wonder if putting the soap in the fridge might have been part of the problem. The heat generated by the saponification process would, I think, help the soap parts bond better...I could be wrong of course.

I'm posting this question as a page in hopes that one of our readers will have some suggestions for you. I'm quite curious now myself.

When you spray the alcohol on first and then pipe, it forms a barrier between the base and the piping. Next time pipe first and then spray the top of the piped soap. I made the same mistake before on a beautiful soap and was so upset when it separated. But thank God you can always use what came off for embeds in another project! 😉
