I found this on epicurious a couple of years back and made it for my son and I for dessert one night. It was fabulous!
Made for March, 2008 Aussie/New Zealand Swap. What a yummy combination. You can't beat chocolate, marshmallows and bananas blended together in all its ooey, gooey goodness. I thought I had large marshmallows, but they were stale, so I used marshmallow fluff instead. It worked great. I really liked the crispness of the butter/brown sugar coating on the outside of the sandwich. Thanks for sharing, Mom2Rose.
This was a perfect little Valentine's day dessert/snack!! It was like a sophisticated S'more!!
