The flavor was great, though I couldn't taste the Nutella very well over the flavor of the peanut butter. I'm not sure it's worth the expense of the Nutella, since its hard to discern. I may just make my old tried and true no-bake cookies from now on, which are inexpensive and fool-proof. Be sure to check that the sugar is completely dissolved. My first batch came out very grainy and no one would eat them, though I cooked them according to the recipe times.
