Not your usual chocolate and gooey!

Top Review by h.glenda

Made this for a girls get-together and they loved it. I used the full can of sweetened condensed milk as others did so as not to waste. Also used peanut butter instead of chips. The dough was very sticky and stuck in spite of the floured hands, so I used a sheet of waxed paper to press it down and it seemed to work better. I thought I baked mine too long because the edges looked almost too done, but when I cut it, they remained soft and chewy. Thank you!
