Mississippi mud cake pairs a homemade chocolate cake with pecans, coconut, marshmallows and fudgy icing. It is decadent, delicious and loaded with goodness.

If you are looking for a gooey delicious chocolate dessert, this layered Mississippi mud cake recipe is for you. It is like having a cross between rocky road and mud cake and it is beyond delicious.
After making a batch of Mississippi mud brownies recently, we needed more chocolate marshmallow goodness. There is just something about the gooey vanilla marshmallows and rich fudgy icing.
Besides, we live by the Mississippi river, so making food named after it seems like a must. Any excuse to make a delicious cake and fudge frosting is a good excuse to me!
So this cake was a natural way to follow it up. This time all of add-ins we considered in the brownies are actually present.


The pecans and coconut add both great flavor and texture to the cake. However, feel free to leave out one or both if you would like.
It is sure to be delicious either way. In the end the chocolate and marshmallows are the star of the show anyway.
Carlee’s Tips and Tricks
If you like mocha style Mississippi mud recipes, similar to the ice cream flavors, feel free to add a teaspoon or two of coffee extract or instant coffee. A little will just boost the chocolate flavor but more will add that extra layer of coffee taste.

Add in the coconut and pecans if you want or feel free to leave them out. This is your dessert, make it your way!


Once the cake has cooled, you get to the fun part. Using marshmallow fluff can be a bit messy but this is a cake named after Mississippi mud, so embrace it!
You can warm a tub of icing a bit and pour it over the top of the cake. Use a knife or spatula to help it cover the cake the way you want but don’t worry about making it perfect.
Or make your own homemade chocolate icing to pour over the top. Of course that is my preference, I love making frosting!
Top with chopped pecans if desired and allow the icing to set a bit before you serve. Then dig in and feel free to make a mess, it’s a mudslide cake for Pete’s sake!


Can I make this in a 9×13 instead of as a layer cake?
Of course! Just add a few minutes to the bake time and slap the whole tub of marshmallow cream on top of the cooled cake.
Then add the chocolate icing and whatever toppings you want. There may be less mud sliding, but the cake will be super delicious none the less.
