This was good, but I think has the potential to be amazing. Tips for next time:
1. I made this by substituting bourbon for vanilla extract and substituting two of the graham cracker layers with ginger snaps. Delicious, but next time more bourbon in the whipped cream. Couldn’t taste the bourbon in the cake, but I could in the whipped cream by itself.
2. The recipe as written isn’t really meant to span a 9 x 13 pan, which isn’t very clear in the recipe. It’s supposed to be 6 graham crackers wide and long. I made it slightly bigger and thus should have made a little bit more whipped cream. It can also be built and stand by itself on a tray, you just have to be more careful when building it.
