Yeah, the butter alone in a cookie is close to 80 calories, I mean, a chocolate chip cookie recipe starts with an entire cup of butter, and that's before the 3/4C white sugar and 3/4C brown sugar (I also bake a lot) and the two cups of chocolate chips.  I usually do cookie cakes instead of individual cookies, but if you figure one (normal homemade) cookie is about 2T of dough, and 1/4 of that is butter and 1/4 sugar...one T of butter is about 100 calories (at least the butter I use--I just double-checked), so that's approx. 50 calories per cookie in butter alone, not counting the sugar and flour and chocolate chips (rough estimate, obviously). And as you said, that's not a pancake-sized cookie like fats usually eat.
