When ready to serve, optionally garnish with the remaining two graham crackers (crushed up with your hands), miniature chocolate chips, and toasted marshmallows.*
OPTIONAL STEPS: To create chocolate curls, make sure the chocolate bar has been at room temperature, unwrap it, and “peel” it with a vegetable peeler from top to bottom directly over the top of the icebox cake.
*To toast the marshmallows spread the remaining 1/4 cup on a parchment lined baking tray. Preheat the oven to broil (temperature of 550 degrees F). Place the oven tray at the top and put in the marshmallow pan leaving the oven door slightly ajar. Watch the marshmallows carefully and pull out when lightly browned. Allow to cool and then pull off and place on icebox cake.
