Once done, microwave the jar of chocolate frosting for about 15 seconds to soften (remove the lid and foil before heating in the microwave).
Remove and stir the frosting. It should be easy to spread now.
Remove the plastic wrap from the pan and spread the chocolate frosting evenly over the top layer of graham crackers.
Cover the pan with plastic wrap and refrigerate overnight to cool.
This dessert gets better with time. The graham crackers need plenty of time to soften.
Once done, slice and serve!
