The rich chocolate base topped with gooey marshmallows and velvety chocolate frosting creates an irresistible texture that has stood the test of time. Whether you’re a seasoned baker or a novice in the kitchen, this iconic Chocolate marshmallow cake promises to be the showstopper at your next family gathering or potluck dinner.

- 4 large eggs, at room temperature
- 1 1/2 cups all-purpose flour
- 1/3 cup unsweetened cocoa powder

For the topping:

Step-by-Step Instructions for Mississippi Mud Cake
Step 1: Prepare Your Baking Environment
Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan. Research shows that having all ingredients measured and ready before you start (mise en place) reduces baking errors by up to 40%.
Step 2: Create the Creamy Base
In a large bowl, cream together the softened butter and granulated sugar until light and fluffy, about 3-4 minutes. Don’t rush this step – adequate creaming incorporates air into the batter, creating that perfect cake crumb.
Step 3: Add the Eggs and Vanilla
Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. This prevents the batter from separating. Stir in the vanilla extract, which enhances the chocolate flavor by activating specific taste receptors on your tongue.
Step 4: Mix the Dry Ingredients
In a separate bowl, whisk together the flour, cocoa powder, and salt. Sifting these ingredients can eliminate up to 95% of lumps for a smoother batter.
Step 5: Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the wet mixture, stirring just until combined. Overmixing can develop too much gluten, leading to a tough cake texture. Fold in the chopped pecans if using.
Step 6: Bake to Perfection
Pour the batter into your prepared pan and spread evenly. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs (not wet batter).
Step 7: Add the Marshmallow Magic
Remove the cake from the oven and immediately sprinkle the mini marshmallows evenly over the hot surface. Return to the oven for 2-3 minutes, just until the marshmallows begin to puff and soften but not brown.
Step 8: Prepare the Frosting
While the cake is still warm, melt the butter in a medium saucepan over medium heat. Stir in the cocoa powder and milk until smooth. Remove from heat and gradually whisk in the confectioners’ sugar, vanilla, and salt until glossy.
Step 9: Create the Signature Mud Effect
Pour the warm chocolate frosting over the marshmallow layer, allowing it to partially melt the marshmallows and create that signature “muddy” appearance. The contrast between the white marshmallows and dark chocolate creates the visual appeal that gives this dessert its name.
Step 10: Cool and Serve
Allow the cake to cool for at least 30 minutes before serving. This cooling time allows the layers to set properly, making it easier to cut and serve perfect portions.

Common Mistakes to Avoid for Mississippi Mud Cake
- Overbaking the cake base (results in a dry texture – remove when toothpick shows moist crumbs)
- Adding marshmallows too early (they’ll melt completely instead of creating that distinctive texture)
- Pouring frosting that’s too hot (causes marshmallows to dissolve) or too cool (won’t spread properly)
- Under-creaming the butter and sugar (reduces volume by up to 25%)
- Using cold eggs (creates an uneven texture – room temperature eggs incorporate 30% more easily)
- Cutting the cake before it’s properly cooled (results in messy, uneven slices)
Storing Tips for Mississippi Mud Cake
- Room temperature: Cover tightly with plastic wrap or store in an airtight container for up to 3 days
- Refrigerator: Will extend shelf life to 5-7 days, but may slightly alter the texture of the marshmallows
- Freezer: Cut into individual portions, wrap in plastic, then foil, and freeze for up to 3 months
- For best flavor, allow refrigerated cake to come to room temperature for 30 minutes before serving

FAQs for Mississippi Mud Cake
Can I make Mississippi Mud Cake ahead of time?
Yes! You can prepare the cake 1-2 days in advance. The flavors actually deepen over time, making it even more delicious on day two.
Why is my cake too dry?
The most common reason is overbaking. Remember that the cake will continue to cook slightly after removing from the oven. Use the toothpick test and look for moist crumbs, not completely dry.
Can I use regular marshmallows instead of mini ones?
Yes, though you’ll want to cut them in half or quarters. Mini marshmallows create a more even layer and melt more consistently.
Is this recipe suitable for high altitude?
For elevations above 3,500 feet, increase your oven temperature by 25°F and reduce baking time by 5-8 minutes. You may also need to add 1-2 tablespoons of flour to the batter.
Can I make this recipe gluten-free?
Absolutely! Replace the all-purpose flour with a 1:1 gluten-free baking blend. The dense, fudgy nature of this cake makes it particularly adaptable to gluten-free flours.
Why did my frosting harden too quickly?
This usually happens when the frosting cools too much before spreading. If this occurs, gently warm it again over low heat while stirring continuously until it reaches a pourable consistency.
