I'm going out on a limb to say that Nutella has a high enough fat content to absorb it all. It's to the same effect in both recipes- heat the weed, then absorb escaping thc in fat. All you are really doing with the oil is taking a few extra steps so you don't have to sit down with a tooth pick and pluck ground up weed out of your teeth. I'm not trying to argue that you should be eating firecrackers over brownies (in fact, you should be more adventurous with your edibles than to limit it to baked goods). And a bit of a tangent, but discussing personal experiences (buzz types) is kind of silly anyway, I shouldn't have brought it up. There are so many factors when preparing edibles (how finely ground the weed is, temperatures, fat contents, ratio of weed to fat, and of course strain, and general quality of weed used).
