Mississippi Mud Cake
Equipment
- 1 9x13-inch baking pan greased and lined with parchment
- 1 Large mixing bowl
- 1 Whisk
- 1 Saucepan for topping
Ingredients
- 2 cups all-purpose flour
- 2 cups granulated sugar
- 0.5 cup unsweetened cocoa powder
- 1 teaspoon baking powder
- 0.5 teaspoon salt
- 1 cup butter melted, divided
- 2 eggs
- 0.5 cup milk
- 1 teaspoon vanilla extract alcohol-free
- 3 cups mini marshmallows
- 1 cup chocolate chips or chopped chocolate
- 2 cups powdered sugar
- 0.25 cup milk for topping
Instructions
- Heat the oven and grease your baking pan well. Lining it with parchment helps make lifting and slicing much easier later.
- Whisk the flour, sugar, cocoa powder, baking powder, and salt in a large bowl until evenly combined. This helps the chocolate flavor distribute throughout the cake.
- Stir in the melted butter, eggs, milk, and alcohol-free vanilla extract. Mix just until the batter is smooth and no dry streaks remain.
- Spread the batter into the prepared pan and bake until the center is set. The cake should look firm around the edges and slightly soft in the middle.
- While the cake is still warm, scatter the mini marshmallows evenly over the top. Let them soften and puff slightly from the heat of the cake.
- Melt the butter, milk, chocolate chips, and powdered sugar together until smooth and glossy. Stir carefully so the frosting becomes silky and easy to spread.
- Pour the warm topping over the marshmallows and spread it gently. Let the cake cool so the layers set before slicing.

This cake delivers deep chocolate flavor with a soft, tender crumb and a gooey topping that bakes into the top just enough. It is easy to make, feeds a crowd, and tastes even better after it cools and settles.
Mississippi Mud Cake Ingredients & Substitutions
- All-purpose flour, for the cake base
- Granulated sugar, for sweetness
- Unsweetened cocoa powder, for rich chocolate flavor
- Butter, melted, for moisture and depth
- Eggs, for structure
- Milk, to bring the batter together
- Alcohol-free vanilla extract, for warmth
- Baking powder, for lift
- Salt, to balance the sweetness
- Mini marshmallows, for the classic gooey topping
- Chocolate chips or chopped chocolate, for the frosting layer
- Powdered sugar, for a smooth finish

Step-by-Step Instructions to Make Mississippi Mud Cake
1. Prepare the pan and oven
Heat the oven and grease your baking pan well. Lining it with parchment helps make lifting and slicing much easier later.
2. Mix the dry ingredients
Whisk the flour, sugar, cocoa powder, baking powder, and salt in a large bowl until evenly combined. This helps the chocolate flavor distribute throughout the cake.
3. Add the wet ingredients
Stir in the melted butter, eggs, milk, and alcohol-free vanilla extract. Mix just until the batter is smooth and no dry streaks remain.
4. Bake the cake layer
Spread the batter into the prepared pan and bake until the center is set. The cake should look firm around the edges and slightly soft in the middle.
5. Add the marshmallows
While the cake is still warm, scatter the mini marshmallows evenly over the top. Let them soften and puff slightly from the heat of the cake.
6. Make the chocolate topping
Melt the butter, milk, chocolate chips, and powdered sugar together until smooth and glossy. Stir carefully so the frosting becomes silky and easy to spread.
7. Finish and cool
Pour the warm topping over the marshmallows and spread it gently. Let the cake cool so the layers set before slicing.
Tips for Success
Do not overmix the batter, or the cake can turn dense. Spread the frosting while it is still warm so it glides over the marshmallows evenly. For the cleanest slices, let the cake cool fully before cutting.
Variations of Mississippi Mud Cake
You can stir chopped pecans into the batter for extra crunch, or add a handful of chocolate chips to make the cake even richer. If you like a deeper cocoa taste, use dark cocoa powder in place of regular cocoa.
For a fun twist, top the cake with toasted coconut or a drizzle of caramel just before serving. You can also bake it in a larger pan for thinner squares that are easy to share.
Serving Suggestions: What to Pair with Mississippi Mud Cake
This cake is lovely with a scoop of vanilla ice cream or a spoonful of lightly sweetened whipped cream. A glass of cold milk or a cup of hot coffee also balances the sweetness beautifully.
Storage & Reheating Instructions
Store leftovers covered at room temperature for a day or in the refrigerator for up to 4 days. If you prefer it warm, heat individual slices briefly in the microwave until the topping softens slightly.
Memories Made Around the Table
There is something comforting about a cake like this, because it invites people to linger a little longer. I love desserts that feel generous, simple, and ready to bring everyone back for one more slice.
FAQs
Can I make Mississippi Mud Cake ahead of time?
Yes, it actually holds up well when made ahead. The flavors settle nicely as it cools, and the topping sets for easy slicing.
Can I use a different pan size?
Yes, but the baking time may change. A larger pan will make a thinner cake, while a smaller pan may need a little extra time in the oven.
Why did my marshmallows melt too much?
That can happen if the cake is too hot or if the topping goes on too late. Add the marshmallows while the cake is warm, not scorching hot, for the best texture.
Can I freeze Mississippi Mud Cake?
Yes, you can freeze it in slices once fully cooled. Wrap each piece well and thaw it in the refrigerator before serving.
Final Thoughts
Mississippi Mud Cake is the kind of dessert that never tries too hard, yet always leaves a big impression. If you love rich chocolate, a soft crumb, and a dreamy topping, this one is worth baking again and again.
