I haven't tried toasting mine. I know they melt well. I made my own version of Pinwheel cookies for my dad---choc cookie, marshmallow on top, dipped in choc. (Definitely weren't weight loss friendly, but wow they were good!) I placed the marshmallow on top when the cookies were still warm and they melted nicely. Next time I make them, which will be soon, I'll try toasting a couple.
