This is a well known, popular Russian cake. With crunchy thin layers of pastry sheets filled with fluffy whipped cream in between.Now, this is not puff pastry type dough, If you like that type of cake you can use store bought puff pastry dough or use this recipe to make your own http://www.aflockinthecity.com/2012/04/17/homemade-puff-pastry-the-quicker-version-by-nick-malgieri/
If using store bought, roll it out in to thin sheets before baking, or you can bake them as is and then separate it to add the cream.
The layers can be baked ahead of time like 1-2 days before, maybe even more(didn’t try ,don’t know)
If you like more crunchy type cake then place it in fridge for 6 hours, if you want it more softer, then you can go for 12 or more hours.
This cake can be versatile using different cream filling http://delightsofculinaria.blogspot.com/2011/06/russian-napaleon.html or pastry cream (will post recipe soon.) Another great cream filling from http://www.grabandgorecipes.com/dulce-de-leche-napoleon-cake-recipe/
So its up to you to decide which ever you prefer, It will be delicious anyway.
