I tried making chocolate swirl marshmallows once but the swirling did not happen. It just all mixed in. They were good, though. I won't mind if the PB ones end up just like that. But I'd like to do a swirly thing. The marshmallow stuff is not very cooperative when it comes out of the bowl so I have no clue how to make them swirly. I've seen pictures. I know it can be done! But how to do it??

Any ideas or suggestions? 

:) Thanks.

I have no clue but do have an idea. how about when you make the marshmallow, spread it out on Saran Wrap. then spread pb on top. then roll up the marshmallow. so you get like a  jelly roll. 

freeze the log. cut slices and you will have a spiral of pb in the marshmallow.
