For the Cake:
- 1 cup (230 g) unsalted butter
- ½ cup (120 ml) vegetable oil
- 2 cups (400 g) granulated sugar
- ½ cup (100 g) light brown sugar, packed
- 4 large eggs
- 1 teaspoon pure vanilla extract
- 1 cup (240 ml) buttermilk
- 1 ¾ cups (220 g) all-purpose flour
- ½ cup (45 g) unsweetened cocoa powder
- 1 teaspoon baking soda

For the Marshmallow Layer:
- 3 cups (about 150 g) mini marshmallows
For the Frosting:
- ½ cup (115 g) unsalted butter
- ⅓ cup (30 g) unsweetened cocoa powder
- ⅓ cup (80 ml) milk
- 3 cups (360 g) powdered sugar, sifted
- 1 teaspoon vanilla extract
- Optional: ½ cup chopped nuts or shredded coconut for topping
Instructions
- Preheat Oven:
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan and line it with parchment paper for easy removal. - Make the Cake Batter:
- In a saucepan, melt butter over medium heat. Stir in vegetable oil, granulated sugar, and brown sugar. Remove from heat and let cool slightly.
- Whisk in eggs and vanilla extract until smooth.
- In a separate bowl, combine flour, cocoa powder, baking soda, and salt.
- Alternately add the dry ingredients and buttermilk to the wet mixture, beginning and ending with dry ingredients. Mix until just combined.
- Stir in the nuts (if using).
- Bake the Cake:
Pour the batter into the prepared pan and bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean. - Add the Marshmallow Layer:
Remove cake from the oven while it’s still hot. Immediately scatter mini marshmallows evenly over the surface. Let them soften and melt slightly into the warm cake. - Prepare the Frosting:
In a saucepan, melt butter over medium heat. Add cocoa powder and milk, whisking until smooth. Remove from heat and gradually stir in powdered sugar and vanilla until thick and glossy. - Frost the Cake:
Pour the warm frosting over the melted marshmallow layer, spreading gently with a spatula to cover the entire surface. Sprinkle with nuts or coconut if desired. - Cool and Serve:
Allow the cake to cool completely before slicing. Serve at room temperature or slightly warm for an extra gooey texture.
Origin and Cultural Significance
The Mississippi Mud Cake has its roots in the American South, particularly in Mississippi during the mid-20th century. The name comes from the cake’s appearance — rich, dark, and dense — said to resemble the thick, muddy banks of the Mississippi River.
This dessert embodies Southern hospitality, where chocolate, butter, and sweetness reign supreme. Over time, it became a symbol of comfort and celebration, appearing at church gatherings, potlucks, and family suppers throughout the region.
Description
Each bite of Mississippi Mud Cake is a symphony of textures and flavors: a moist, fudgy chocolate base, a gooey marshmallow layer that melts into the cake, and a silky frosting that ties it all together. The contrast between the dense chocolate cake and the fluffy marshmallow topping creates pure decadence — a Southern classic that feels both nostalgic and luxurious.
Optional Additions
- 🍫 Chocolate chips – add extra richness to the batter.
- ☕ Espresso powder – enhances the depth of chocolate flavor.
- 🥥 Toasted coconut – adds a tropical twist.

Tips for Success
- Use real buttermilk for the best texture and tangy depth.
- Don’t overbake — slightly underbaked cake yields that signature gooey texture.
- Frost while warm — so the frosting and marshmallows melt slightly together.
- Sift powdered sugar for a smooth, lump-free frosting.
- Cool completely before slicing to achieve neat, beautiful squares.
