Allow the ganache to cool slightly, then pour over the top layer of graham crackers. Evenly spread over the cake with a clean silicone spatula.
Cover the cake and allow to sit in the fridge for at least 4-6 hours or overnight to allow the crackers to soften and the ganache to set.
Once ready to serve allow it to sit on the counter for a few minutes for the ganache to soften a bit, then use a spatula to cut slices of cake. Enjoy within 24 hours!
