end-of-summer cobbler

It always seems a waste to me to cook really great fresh fruit, but we weren't consuming the peaches at the rate that they were ripening.

blueberry peach cobbler
I can never get the names right: cobbler, betty, crumble, pandowdy... Anyway, whatever this one is, I used a batter dough, which goes on the bottom, and the fruit is poured on top. It all goops together in one doughy, fruity mass. I think I had way too much fruit, so I should have baked this for longer, because the dough in the middle was a little on the raw side.
