Is there a dead easy even-a-child-could-do-it blog tech for recipes

I'm trying to get the kids more interested in cooking and as a hook I said we could blog about it. I thought this would also be nice as after a few months we'd have an index of a few recipe they know how to make. The audience is just us, and I just want something that is easy to post photos to and has a recipe plugin and that is dead easy to post to.

I don't need my own domain and don't want to have to host it and preferably free.

I do work in digital so not a complete noob, but just haven't done anything like this in years so don't know the current market. Also, while I don't mind a bit of sweat and tears, I do want my kids (8 & 10) to enjoy posting.

thanks
