Peach..Something??

So I have some Fredericksburg peaches.. they have been in a paper bag by a window for a couple days.. They need to be used tomorrow. And I can't decide between making a peach pie, or peach upside down cake. They both sound SO good! I also have some frozen mixed berries in the freezer that could be used in whatever I decide to make.. but I can't decide which to make! lmao
