Tasty treats for a truly worthy cause — that’s what this annual event is all about. For the 8th year in a row, Flour Bakery is offering the opportunity to bring in two dozen of your favorite holiday cookies and sample the creations of other attendees, with all ticket proceeds going to Room to Grow, a nonprofit dedicated to improving the lives of babies born into poverty. Flour will have pastry boxes and festive beverages on hand, and will also be compiling a book with participants’ recipes. Tickets $35.
