This is from recipegoldmine.com. I was looking for Nutella recipes and no one has posted this one. I made a variation of this with walnuts instead of hazelnuts and didn't roll in nuts just the confecioners sugar. They turned out great but I did find I had to bake them about 15 minutes to get the middle done and to crackle on top. I didn't count my cookies so maybe I made them too big. I think you could make them with any nuts you have on hand, the Nutella flavour is still there.UPDATE..In the picture I made them with hazelnuts but I didn't notice any difference in taste than when I made them with walnuts. Walnuts I get free and hazelnuts are so expensive to buy.
