Cookies are too sweet I made chocolate chip cookies and added too much brown sugar. The cookies are too sweet. I've used real butter and real chocolate chips. Does anyone have any ideas?
You might be able to overcome the sweetness by adding a tart glaze to the cookies (lemon or lime), but I don't know how well that'll go with the chocolate chips.  Another option would be to crush them up to make a yogurt parfait (made with plain, unsweetned yogurt).

You might also consider some of the options mentioned in What can I use hard, crunchy, leftover cookie-mistakes for?
