These are wonderful. It took me a while to find this recipe after tasting these at a party that was catered. I would eat the whole pan if I hadn't given them away. But everyone was so grateful for me doing so and they loved!!! them and said the couldn't stop thinking about them. Note: I did use marshmallow fluff since it's easier to spread and it turned out great and is still ooey gooey in the middle. ***Have now tried a brownie mix for the base and it's just as good and a little quicker to make.***
