Ingredients and Their Roles
Each ingredient in this Mississippi Mud Cake recipe serves a purpose in creating that iconic Southern texture and flavor.
• 1 cup unsalted butter (melted) – Adds rich flavor and moistness, ensuring a tender cake crumb.
• 2 cups granulated sugar – Balances the deep cocoa notes with sweetness and helps create a shiny crust.
• ½ cup unsweetened cocoa powder – The heart of the cake; provides the bold chocolate foundation.
• 4 large eggs – Bind the batter and add structure, giving the cake its soft, velvety consistency.
• 1 ½ cups all-purpose flour – Builds the base while keeping the texture light yet dense enough to hold the toppings.
• 1 teaspoon baking powder – Ensures the cake rises just enough without becoming airy.
• ¼ teaspoon salt – Enhances every sweet bite and balances the chocolate flavor.
• 1 teaspoon vanilla extract – Adds warmth and depth to the cake’s aroma.
• 1 cup chopped pecans (optional) – Adds a delightful crunch and nutty richness.
• 3 cups mini marshmallows – Melt into the warm cake, creating that gooey, signature mud effect.
For the frosting:
• ½ cup butter – Provides a creamy base for a smooth frosting.
• ⅓ cup milk – Thins the frosting to a pourable consistency.

Step-by-Step Instructions
1. Preheat and Prep – Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan and line it with parchment paper for easy removal.
2. Mix the Base – In a large bowl, whisk together melted butter, sugar, and cocoa powder until smooth and glossy.
3. Add the Eggs – Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Stir in vanilla extract.
4. Combine Dry Ingredients – In a separate bowl, whisk together flour, baking powder, and salt. Gradually fold this into the wet mixture until just combined. Avoid overmixing to keep the cake tender.
5. Add Pecans – Fold in chopped pecans for added crunch (optional but recommended).
6. 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 slightly fudgy but not wet.
7. Top with Marshmallows – Immediately after removing the cake from the oven, sprinkle mini marshmallows evenly across the surface. Return to the oven for 2–3 minutes, just until the marshmallows puff and soften.
8. Prepare the Frosting – In a saucepan, melt butter over medium heat. Whisk in cocoa powder and milk until smooth. Remove from heat and stir in powdered sugar and vanilla until glossy.
9. Finish the Cake – Pour the warm frosting over the marshmallow layer. Use a spatula to spread it evenly, letting it seep into the marshmallows for that signature mud-like texture.
10. Cool and Serve – Allow the cake to cool completely before slicing. For an extra treat, serve slightly warm with a scoop of vanilla ice cream or a drizzle of chocolate sauce.
