I need to work on the crust of this bad boy. But. I'll share the idea. If you love smores, you might want to work on your own crust.
You could use the whole crushed graham crackers, a little bit of Earth Balance, pressed into a 9 x 13 pan. Or cookie dough of your choice baked until done.

Toss the marshmallows onto the chocolate and press down. Stick under the broiler and toast them until they turn golden and start to melt.
Cool for ten minutes or so. Then cut into bars.
