So who doesn't love the combo of chocolate and peanut butter? Add a crispy, crunchy texture along with some marshmallow cream and you've got yourself the king of all bar cookies. I know, that's a bold statement, but these delicious bars are sure to go quickly at your house. There is peanut butter in the marshmallow cream AND it is also mixed into the top layer. You can't go wrong with two layers of peanut buttery goodness. If you want the gooey-ness of the marshmallow cream, leave these at room temperature. I actually like them cold so I store them in the fridge.

    This recipe is very confusing and out of order. Where do you put the melted butter and chocolate? In the brownie layer? That's what I did. I hope they turn out ok.

      Hi Adrienne- thank you so much for pointing that out! I fixed the instructions. I had one sentence in the wrong place. Your instincts were right! The melted butter and chocolate go in the brownie layer. So sorry about the error and I hope they turned out well!
