Dawn, could your butter have gotten too warm? Other possibilities...
-Dough was not chilled enough?
-Dough placed on warm, not cool, cookie sheets?
-Dough was overmixed (not sure about this one)?
-Oven temp was too high?
For a while, I was turning out duds, and couldn't figure it out. I read that if you leave the butter out, and it gets too warm, it'll never be good for cookie baking, as the molecular structure changes, even if you chill the dough after you make it.
I would have that happen fairly frequently, as I leave the butter out on the counter to come to "room temperature". Of course, my "room" in Hawaii is much warmer than your "room" in NY, so maybe you wouldn't have that problem smileys/smile.gif
If none of the above, I'd chalk it up to the Christmas Cookie grinch! He visits at least one person per season - boo!
I'm sure the recipients were thankful for the homemade cookies, nonetheless smileys/smile.gif
Happy New Year!
