Granny Squares 3

For those that just joined us, let me recap the Granny Squares Project. A friend of mine has a recipe from a member of her family called Granny Squares. A wonderful little gooey bar cookie recipe, and for a few weeks now I have been trying to find the perfect size pan and length of baking time for the squares. Now don't get me wrong I am not trying to change Granny Squares, no, just trying to make them fit my family's taste. So this is Granny Squares version 3.
Granny Squares 1 was a half sheet pan baked at 18 minutes. It was good but some thought they needed to be thicker and gooier. Granny Squares 2 was a 9x13 pan baked for 25 minutes some thought that they were the correct thickness just too gooey. Today's recipe, Granny Squares 3, was a 9x13 pan baked for 35 minutes.
Drum roll, please. Ladies and Gentlemen-we have a winner!!!! Confetti! Applause! Granny Squares 3 is it! Whew, now I can move on with my life. This was the correct thickness, not too gooey, but just gooey enough. So now it is your turn to find which Granny Square is right for you!
