Okay... I cheated a little in the sense that I used a brownie mix that is imported to Turkey from Germany but I don't know if I've ever had a better mix (even the gooey, gluten laden ones can't match up). So forgive me. Once I mixed the batter, I threw in about a cup full of dark chocolate chips for good chocolatey measure and then I spooned part of the mixture into greased muffin tins. I cut up a Bounty bar into bit sized pieces and stuffed one bit in the middle of each brown cup and baked as directed to on the box. I don't know if the chocolate bar made it more gooey or what but they were delicious!!!! So get creative with your brownies, people! It's well worth it.
