I wondered, too, about the butter. I thought that perhaps it should be 1 stick, rather than a cup. My fear is the amount of almonds it would take to grind into that much "almond flour" would contain a whole lot of carbs, and a tremendous amount of calories, besides. I'm sure it wouldn't be "legal" for induction, but they sure do sound yummy, and I'll be trying the recipe in another few weeks, after I lose some more. (I don't dare chance it yet).
