Tasty idea that almost, almost made it to a top ten list.
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.
Then dump 1 1/2 or 2 cups of chocolate chips over the crust and allow them to soften from the heat of the crust. (If you don't bake the crust, you might want to melt the chips with a TBSP of coconut oil or peanut butter and pour over the crust. Use a bag of Dandies marshmallows. Cut each one in half (I used the standard sized bag and the large size of marshmallows if they come in other sizes...)
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.
