It’s fundraising, Flour style. Come eat your weight in cake and do some good (well, maybe not for your waistline) at the bakery’s Cambridgeport location — located at 40 Erie Street — on Sunday, July 15th. If you dream of buttercream and ganache, then this is your heavenly fantasy come to life, and there’ll be no shortage of slices to savor. Pile on pieces of midnight chocolate, lemon raspberry, carrot cake, Boston cream pie, and more to your plate to make the most of this unlimited extravaganza. Proceeds go to Silver Linings Mentoring Foundation, an organization that helps youth in foster care develop life skills through one-on-one volunteer mentorship. Grab your tickets for the 1:00pm, 3:00pm or 5:00pm sugary slots at $30 apiece.
