Very, very chocolatey and gooey. Perfect Mississippi Mud. Made without nuts as my kids prefer their brownies without nuts so I didn't think they would go over here either. Made for CQ 2014.

Holy Cow, Lynn.....I've never had anything quite like this cake. I wish it had come out a little prettier, but I wasn't ready for the "Michelin Man" effect. Maybe it had something to do with the fact that I halved the recipe and used a smaller baking dish. However, didn't affect the delicious richness. Thnx for sharing your recipe. Made for Comfort Cafe Snow Queen Chalet Jan 2010.

This was such a delicious desert. I made it when my inlaws came over for lunch and it was decadent and delicious and OH SO rich. We had other people around at the same time, and they were still talking about it today! Thanks for a perfectly fabulous recipe!
