GiveDirectly. They give cash, no strings attached. So hardly any overhead. NPR Planet Money tried to have a guy build a school in Haiti. They were flush with donations. After all was said and done, a year later they barely had a concrete foundation. That was it. They asked the guy, a highly experienced American contractor/builder/etc. if, starting over, he'd have just given them cash. He said, "Definitely." GiveDirectly was started because charities like Red Cross do so badly.
