Ingredients
Equipment
Instructions
- Preheat the oven to 350F.
- Mix together all of the dry ingredients (all-purpose flour, sugar, brown sugar, unsweetened cocoa powder, baking powder, baking soda, and salt) in a large mixing bowl using a whisk.
- Add vegetable oil, eggs, whole milk, sour cream, and vanilla extract to the dry ingredients. Mix together using an electric mixer at low speed. Then, slowly add boiling water while beating.
- Grease a 9×13-inch baking dish with nonstick cooking spray. Then, transfer the chocolate batter to the greased baking dish. Bake in the preheated oven for 25-30 minutes or until ready. Check the readiness of the chocolate mud cake using a toothpick inserted in the center, if it comes out clean – the cake is ready.
- Remove your easy Mississippi mud cake from the oven and top with mini marshmallows. Then, return the chocolate mud cake to the hot oven. Bake for additional 2-4 minutes or until mini marshmallows is puffed and lightly browned. Remove the baking dish from the oven and let it cool to room temperature.
- While the chocolate mud cake is cooling, prepare the chocolate topping. In a saucepan, melt unsalted butter. Then, stir in the whole milk and unsweetened cocoa powder. Cook, stirring constantly until the mixture is completely heated and combined (usually it takes about 2-3 minutes). Then, remove the saucepan from the heat, add vanilla extract and slowly add powdered sugar, beating after each addition using an electric mixer. Pour over the cooled chocolate mud cake. Place the cake in the refrigerator to set the topping. Then, slice and enjoy!

Tips From Chet Thomas
Always bring your cold ingredients like eggs, milk, and sour cream to room temperature before mixing. It helps them combine better and results in a smoother batter.
Don’t overmix your batter once the wet and dry ingredients are combined. Mix just until everything is incorporated to keep the cake tender.
Let the cake cool down fully before you add the topping. If the cake is warm, the topping will just melt and slide off. Patience here makes a difference.
For an extra depth of flavor, use a good quality unsweetened cocoa powder. It really shines through in this type of cake.
How I Serve Mississippi Chocolate Mud Cake
This Mississippi Chocolate Mud Cake is already a complete dessert on its own, but sometimes a little something extra can make it even better much like the simple elegance of my Gluten-Free French Butter Cake. I often serve it with a simple dollop of freshly whipped cream. The cream cuts through the richness of the chocolate nicely.
A scoop of vanilla bean ice cream is another classic choice that everyone seems to enjoy. For a more casual feel, a glass of cold milk alongside a slice is hard to beat, especially for the younger folks. If you are looking for a different kind of cozy afternoon treat, you might also enjoy my Easy Moist Banana Bread.
For those looking for more delicious ideas, adding fresh berries like raspberries or strawberries can provide a lovely contrast to the cake’s richness, as suggested by many culinary enthusiasts. Itโs all about what feels right for your table and your family.

FAQ About Mississippi Chocolate Mud Cake
What makes this a “mud cake”?
A mud cake usually refers to its dense, rich, and moist texture, which can feel somewhat like wet mud. It’s known for being very chocolatey and decadent.
Can I use milk chocolate instead of unsweetened cocoa powder?
This recipe is designed for unsweetened cocoa powder to achieve a deep chocolate flavor. Using milk chocolate would change the texture and sweetness balance significantly. I recommend sticking to the unsweetened cocoa for this specific recipe.
Why do my marshmallows get too hard or burn?
Marshmallows can cook very quickly. Keep a close eye on them during those last 2-4 minutes in the oven. They just need to puff up and get lightly browned. If they cook too long, they can seize up or burn.
Can I freeze Mississippi Chocolate Mud Cake?
Yes, you can freeze the cake without the marshmallow topping and frosting. Wrap it tightly in plastic wrap, then in foil, and it will keep for up to 2-3 months. Thaw it in the refrigerator overnight before adding the topping.
My topping is too thick or too thin. What did I do wrong?
If the topping is too thick, you can slowly add a tiny bit more milk, a teaspoon at a time, until it reaches a pourable consistency. If it’s too thin, try adding a little more powdered sugar, a tablespoon at a time, until it thickens up.
Is it important for the eggs and milk to be at room temperature?
Yes, it is. Room temperature ingredients blend together much more smoothly and create a more uniform emulsion, leading to a better texture in your finished cake. Cold ingredients can cause the batter to curdle slightly.
