What's more fattening, [cookie] dough or a cooked cookie?

Booooo!

Assuming you aren’t burning them into charcoalish lumps, like my cousin. (He does it deliberately. I don’t get it.)

Where he gets to frolic with the sheep to his heart’s content. :smiley:

All else being the same, a lump of cookie dough will be less fattening if eaten raw than if cooked because the dough contains eggs. Cooked egg whites are roughly 90% metabolized while raw egg whites are only around 50% metabolized:

Technically yes but egg whites contribute a tiny amount to the total calories, compared to fats and sugars. Because of the practical nature of the OP’s question the egg white issue probably doesn’t matter.

In general, cooking foods makes calories more accessible for digestion, which is a big part of the reason that the cooking fad caught on.

That would depend if you put any butter or spray on the cookie sheet .

Don’t you lose some fat from the baking and cooling processes? The dough will always exude some oil to the baking pan and cooling/drying surface.

I was wondering the same thing. I figured the fat that ends up on the tray, napkin, etc. would contain some of the calories that were in the raw dough.
