A Nutella Newbie

I don't usually buy Nutella, but it seems to have a cult following these days. I decided to try a cookie recipe yesterday that featured the adored product. The  recipe is from Two Peas and a Pod. No eggs was the first weird thing I noticed. I may not have cooked mine quite long enough, but they seem to almost have a truffle like consistency to me. Son said-these gonna stiffen up? Daughter said-oohh I like these! I am undecided about the cookie, but know they require drinking milk to enjoy. I will probably try another recipe.
