Paula Deen Mississippi Mud Cake Ingredients
For the Cake:
- 2 cups sugar
- 1/2 teaspoon salt
- 2 cups all purpose flour
- 1 stick unsalted butter
- 1/2 cup Vegetable oil
- 1/2 cup cocoa
- 1/4 cup water
- 2 eggs
- 1 teaspoon baking soda
- 1/2 cup buttermilk
- 2 teaspoons vanilla extract
- 1 bag miniature marshmallows
For the Icing:

- 6 tablespoons milk
- 1 (1 lb) box confectioner’s sugar
- 1 cup chopped pecans (or walnuts)
- 1 teaspoon vanilla extract
How To Make Paula Deen Mississippi Mud Cake
- Prep Oven and Make Batter Base: Preheat the oven to 350°F. Grease and flour a 13×9-inch baking pan. In a large mixing bowl, combine the sugar, salt, and flour.
- Make the Chocolate Liquid: In a saucepan, bring one stick of butter, the oil, 1/2 cup of cocoa, and 1/4 cup of water to a boil. Pour this hot liquid over the flour mixture and mix well.
- Finish the Batter and Bake: In a separate small bowl, beat together the eggs, baking soda, buttermilk, and 2 teaspoons of vanilla. Add this to the chocolate mixture, mix well, and pour the batter into the prepared pan. Bake for 25 minutes.
- Make the Icing: While the cake is baking, melt 1 stick of softened butter with the 3 tablespoons of cocoa and the milk in a saucepan over low heat. Bring the mixture to a boil, then remove it from the heat. Stir in the confectioner’s sugar until smooth. Slowly mix in the chopped nuts and the 1 teaspoon of vanilla.
- Top the Cake and Cool: As soon as you take the cake from the oven, and while it is still hot, cover the entire surface with the miniature marshmallows. Pour the warm icing evenly over the cake and the marshmallows. Let the cake cool completely before serving.

Recipe Tips
- How to get the perfect gooey marshmallow layer? The secret is to top the cake with the marshmallows while the cake is still hot from the oven. This allows them to soften slightly. Then, immediately pour the warm (not scorching hot) icing over the top, which will further melt the marshmallows into a perfect gooey layer.
- Can I make this cake ahead of time? Yes, absolutely. This cake is fantastic for making a day in advance. The flavors will meld, and the texture will be perfect. Just keep it covered at room temperature.
- What’s the best way to get a non-lumpy icing? For the smoothest possible icing, it’s a good idea to sift your confectioner’s sugar before you stir it into the hot butter and milk mixture.
- Can I use a different kind of nut? Yes. While pecans are the classic Southern choice, this cake is equally delicious with an equal amount of chopped walnuts. For a deeper flavor, try toasting the nuts before you add them to the icing.
What To Serve With Mississippi Mud Cake

How To Store Mississippi Mud Cake
- Room Temperature: This cake can be stored, covered, at room temperature for up to 4 days.

FAQs
It’s a classic Southern dessert that is similar in style to a Texas Sheet Cake. It features a rich, moist chocolate cake base that is topped, while still hot, with a layer of marshmallows and a cooked chocolate-pecan frosting that all melt together into a gooey, “muddy” topping.
This can happen if your icing was too hot when you poured it over the top. The icing should be warm and pourable, but not boiling hot, to ensure the marshmallows soften and become gooey without completely dissolving.
Buttermilk is a classic ingredient that provides a slight tang and a very tender crumb. If you don’t have any, you can make a DIY substitute by adding 1/2 tablespoon of white vinegar or lemon juice to 1/2 cup of regular milk and letting it sit for 5 minutes.
