I prefer the subtly warmer shot at the top, in terms of white balance/color rendering. One suggestion...more depth of field will show us more cookie goodness! Try and get some depth of field! WIth the image magnified so much as this, it's going to take a SMALL f/stop, like f/16 to f/32 to get any "significant" depth of field with a non-tilting lens...if you have a way to tilt the lens, like say, the Lensbaby Composer for example, you might be able to pull greater DOF, and make some cool shots.
Could you try this again? (I know, hafta make another batch, boo-hoo.)
My main thought is to pose the cookies somewhat differently. Tilt the plate up just a bit, place a reflector opposite the light, a little higher camera position, and maybe not so many crumbs.
