Ooh, gooey good stuff. Do you love chocolate? You'll love these. Love brownies? You'll love these. Love nuts? Then sprinkle some on top. They're irresistible and don't last long. You can also top it with coconut, chocolate sprinkles, chocolate candies, etc. Using a chocolate bar gives these a richer flavor. These bars are not hard to make.

Blue Ribbon Recipe

So sweet and chocolaty, these mud bars are irresistible. The brownie-like layer is rich. Adding sour cream makes the frosting very creamy with a slight tang. What turns this into a memorable dessert is the layer of slightly melted marshmallows. Super rich, a small piece is satisfying.
