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!

Oh, my goodness! This is the best dessert I've made in a long, long time! I used a "cheapie" store-brand chocolate cake mix from Aldi's, knowing that I was adding stuff to it. It was awesome! I didn't have peanut-butter chips so I used chocolate chips instead and added peanut butter (about 1 cup as someone else suggested). I also used the entire can of condensed milk as someone also suggested (didn't want to waste any and had no plans for the 1/4 cup left so just added the extra in the cake mix part). It puffs up nice and lofty and tastes divine! I know that any Kittencal recipe is good before I even make it; but even this one is more than I expected. Thanks, Kittecal, for making me look like such a good baker today at work! Carol

Oh my, this is wonderful!! I used the rest of the can of condensed milk (probably about a cup) and I also used a large jar of marshmallow cream so I had alot more filling. I added extra peanut butter chips too. Very tasty treat. Thanks Kittencal!
