Pumpkin pie layer cake with candied Graham crackers

I wanted to make a cake that reminded you of pumpkin pie, but how to do that? Well, start with a really great basic pumpkin cake recipe (like this one), then add a layer of pumpkin spice syrup (oh yeah), followed by a layer of thick, creamy vanilla buttercream, and – wait for it – candied Graham cracker, to remind you of that beloved Graham cracker crust that you see on a lot of pumpkin pies. Give the whole thing one more loving layer of vanilla buttercream, top with a little more candied Graham cracker, and boom: you’ve got yourself one mighty fine pumpkin pie layer cake to impress your family on Thanksgiving (or even Halloween).
