Mississippi Mud Cake Brownies are rich, fudgy chocolate brownies topped with a gooey layer of mini marshmallows and a thick pourable chocolate frosting studded with pecans. They’re messy in the best way—like a cross between brownies, cake, rocky road, and s’mores—baked in a single pan and perfect for feeding a crowd.
Why you’ll love these brownies
These brownies follow the same structure as classic Mississippi mud cake: a dense chocolate base, a blanket of marshmallows that melt and puff in the oven, and a warm chocolate icing poured over the top so it seeps into the marshmallow layer. Chopped pecans add crunch and a toasty, nutty contrast to all that sweetness, echoing the traditional Southern versions that nearly always include nuts.
The ingredient list is straightforward—pantry cocoa, butter, sugar, eggs, flour, marshmallows, and a simple stovetop frosting—similar to many vintage Mississippi mud cake and brownie recipes. The result is an over-the-top chocolate dessert that slices into generous bars and feels special enough for holidays, potlucks, and celebrations.
