My cake only has 10 layers of crepe, but if you want to the taller cake, here's a link to the original recipe: thekitchn.com: https://www.thekitchn.com/how-to-make-nutella-crepe-cake-the-easiest-method-240548. The crepe recipe I used for this Nutella cake is the same recipe I used for my Mango & Passionfruit Crepe Cake (http://sprinklesandsauce.com/mango-passionfruit-crepe-cake/). If you find it's too sweet with the crushed Ferrero Rocher, you can substitute it with chocolate shavings instead.
