Ingredients You’ll Need
The magic behind this Mississippi Mud Cake comes from simple, everyday ingredients that come together to deliver a chocolate experience like no other. Each component plays a crucial role in creating the perfect balance of moistness, richness, and flavor that defines this dessert.
- All-purpose flour: Provides structure to the cake while keeping it tender and soft.
- Unsweetened cocoa powder: Adds deep chocolate intensity and beautiful color.
- Baking powder: Gives a light lift to the dense batter for the right texture.
- Granulated sugar: Sweetens the cake and helps create a tender crumb.
- Unsalted butter: Enhances richness and moistness with a buttery flavor.
- Large eggs: Bind all the ingredients and add fluffiness.
- Vanilla extract: Brings a subtle sweetness that complements the chocolate.
- Mini marshmallows: Provide that signature gooey, melt-in-your-mouth finish on top.
- Pecans or walnuts (optional): Introduce a delightful crunch and nutty contrast.
How to Make Mississippi Mud Cake
Step 1: Preparation and Oven Setup
Start by preheating your oven to 350°F (175°C). Make sure to grease your baking dish thoroughly so that the cake won’t stick. This simple step ensures your Mississippi Mud Cake will come out beautifully intact and ready to impress.
Step 2: Mix the Dry Ingredients
In a large mixing bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking powder, and granulated sugar until evenly combined. This blend is the foundation for the rich, deep chocolate flavor that defines Mississippi Mud Cake.
Step 3: Combine the Wet Ingredients
In a separate bowl, mix melted unsalted butter with large eggs and vanilla extract until smooth and fully incorporated. This mixture adds moisture and richness that will make your cake irresistibly soft and fudgy.
Step 4: Bring Wet and Dry Together
Pour the wet ingredients into the dry mixture. Gently stir them together just until everything is combined – overmixing can make the cake tough. This careful balance is key to getting that signature dense yet tender Mississippi Mud Cake texture.
Step 5: Bake the Cake Base
Transfer the batter into your greased baking dish, spreading it out evenly. Bake in the preheated oven for 25 to 30 minutes or until a toothpick inserted into the center comes out clean. This ensures the cake is cooked perfectly without drying out.
Step 6: Marshmallow Topping
Once baked, take the cake out and immediately sprinkle a generous layer of mini marshmallows over the top. Pop it back into the oven for an additional 5 minutes so the marshmallows melt and turn golden brown, creating a bubbly, gooey topping that defines this cake.
Step 7: Optional Chocolate Glaze Finish
For an extra touch of indulgence, melt some chocolate chips together with a bit of butter to create a glossy glaze. Drizzle this warm glaze generously over the marshmallow topping to elevate your Mississippi Mud Cake to decadent heights.
How to Serve Mississippi Mud Cake

Garnishes
The beauty of Mississippi Mud Cake is how effortlessly it shines with simple garnishes. A light dusting of powdered sugar, a sprinkle of chopped pecans or walnuts, or even a few fresh berries can add color and crunch, enhancing the visual appeal and texture without overshadowing the rich chocolate.
Side Dishes
Pair your Mississippi Mud Cake with a scoop of vanilla ice cream or a dollop of whipped cream for an irresistible combination of hot and cold. A cup of strong coffee or a glass of cold milk also complements the cake’s intense chocolate flavors perfectly and rounds out the dessert experience.
Creative Ways to Present
Take your Mississippi Mud Cake presentation to the next level by serving it in individual ramekins or cutting it into squares and stacking them with layers of marshmallow fluff or a drizzle of caramel sauce. Adding edible flowers or chocolate shavings on top turns it into an eye-catching centerpiece that friends and family will rave about.
Make Ahead and Storage
Storing Leftovers
If you happen to have leftovers (which is rare!), wrap the Mississippi Mud Cake tightly with plastic wrap or store it in an airtight container at room temperature for up to 2 days. This keeps the marshmallow topping soft and the cake moist.
Freezing
Mississippi Mud Cake freezes beautifully. Slice it into portions, wrap each piece securely, and place them in a freezer bag. They will keep for up to 3 months. When you’re ready, thaw at room temperature for a few hours before serving to enjoy that fresh-baked taste.
Reheating
To revive the gooey texture after refrigeration or freezing, warm individual slices in the microwave for 15 to 20 seconds. This melts the marshmallow topping slightly and revives that luscious, fudgy mouthfeel that makes Mississippi Mud Cake so beloved.
FAQs
Can I use chocolate chips in the batter?
Absolutely! Adding chocolate chips to the batter can add extra bursts of melty chocolate goodness, which many people adore. Just fold them gently into the batter before baking.
What type of nuts work best with Mississippi Mud Cake?
Pecans and walnuts are the most popular choices, offering a great crunchy contrast and a slightly nutty flavor that complements the chocolate beautifully.
Is Mississippi Mud Cake gluten-free?
Traditionally, it is not, because it uses all-purpose flour. However, you can substitute with a gluten-free flour blend designed for baking to make it suitable for gluten-free diets.
Can I make this cake in a smaller or larger pan?
Yes, you can adjust the baking time accordingly. For a smaller pan, reduce baking time slightly, and for a larger pan, increase it. Keep an eye on the cake and test with a toothpick for doneness.
How long does Mississippi Mud Cake last at room temperature?
Because of the marshmallow topping, it’s best eaten within 1 to 2 days when stored properly at room temperature to keep it fresh and delicious.
