The end result tasted great but these didn't set up very well for me. The peaches part was still quite juicy and liquidy after 4 hours of cooling the bars. I did use some fairly juicy peaches, but I know the mixture was thick when I took it off the stove with the cornstarch. Also, next time, I'd make at least a quarter more of the topping-or possibly double it. There just wasn't very much on top after I used the recommended amount for the base. Possibly using a smaller pan would solve this issue, too. The bars tasted fantastic, but the execution needs some tinkering with.
