Shelf stable recipes for filled bars

Hi, I'd like to create a couple filled bars and am searching for shelf stable recipes.  I'm thinking along the lines of a coconut cream or mint cream.  Thanks!

There are several forms, mostly fondant cremes.  They can be made in a wide range of textures, and can be made in a form allowing further processing, like enrobing, but then soften.  Feel free to contact me for some basic recipes, targeting your textural objectives.

Thanks Mark, I'd love those recipes, I'm thinking york peppermint pattie and a coconut filling heavy on the shredded coconut.  I apparently can't figure out how to send you a private message, so if you like you can contact me at danikiser@gmail.com, that would be awesome.
