You will use the chocolate spread only for the bottom 2 layers. There are a couple different things that make this cake above and beyond, but by adding the "secret" ingredient of sour cream to the cake really makes for a much more moist cake. Also I love the sudden surprise of the Nutella in between each layer. For me it brings me back to being a kid and eating chocolate dipped bananas on a stick...known to some as the "Monkey Tail".
