You do that to? Then I guess you are not alone… 
My next door neighbor had no idea what Nutella was, so I brought out the jar. There were more converts.
I’m still amazed how easily impressed people are. If I had a nickel for every time I heard, “You made homemade whipped cream? Wow!” I’d have, well maybe a quarter.
Other things I learned from making this cake: Hazelnuts are also called Filberts, and they taste terrible raw.
Get some whole grain raisin bread. Spread a slice of it with Nutella (which we pronounce “New-TELL-ah”, but a good friend of mine always used to pronounce “New-TRELL-ah” until I gently pointed out to her that there’s no “r” in it). Eat the raisin bread with Nutella. Get another slice of raisin bread. . .etc. until you run out of either raisin bread or Nutella. It’s like a Raisinet sandwich or something.
Well, more correctly, the Common Hazel (Corylus maxima) and the Filbert (C. avellana) are two different species, but they just differ in some aspects of nut enclosure, and the taste is (reportedly, at any rate) indistinguishable. But it’s usually C. maxima that’s farmed commercially, and is a key plant in the old English hedgerow systems.
All nuts are better roasted, I can’t think of a one I didn’t prefer that way.
