I've never had any trouble taking those things in my carry-on, even as recently as my last flight at the end of August (which was after the 'no-gel, no-liquid' thing). I carried lots of chocolate both ways, and other snacks.
Of course, don't take anything with sharp toys in it and expect to carry it on -- did anyone see the thing on telly with the lady in Luton, trying to get on a plane with a tin of biscuits or chocolate of something with little sharp toys in it? And when they told her she couldn't take it on, she smacked the gate agent in the face with it?
She's now banned form that airline for life.
But otherwise, you should be fine!
