For the Chocolate Cake
- All-Purpose Flour: Provides structure to the cake. Make sure to spoon and level the flour to avoid a dense cake.
- Granulated Sugar: Sweetens the cake and helps keep it moist. Brown sugar can be used in place of the granulated sugar if you prefer.
- Cocoa Powder: The star of the show, cocoa powder gives the cake its deep chocolate flavor. Use unsweetened cocoa for a rich taste.
- Salt, Baking Powder, and Baking Soda: These are the leavening agents and help with flavor balance as well as ensure the cake rises properly.
- Milk: Adds moisture and richness to the cake. Use whole milk for a creamier texture.
- Vegetable Oil: Keeps the cake soft and moist. It’s a key ingredient to get that tender crumb. Canola oil can be substituted in this recipe.
- Eggs: Binds the ingredients together and helps add structure to the cake.
- Boiling Water: Thins the batter, resulting in a moist and fluffy cake. You can substitute with coffee for a deeper chocolate flavor.
For the Toppings and Frosting
- Mini Marshmallows: The marshmallow layer is what makes this cake unique, adding a gooey, sweet finish. Marshmallow fluff can also be used to “frost” the cake.
- Butter: Forms the base of the frosting, adding richness and a creamy texture.
- Cocoa Powder: Unsweetened cocoa powder is what gives this frosting it’s chocolate flavor and color.
- Powdered Sugar: Perfectly sweetens the frosting and gives it a smooth consistency.
- Milk: Thins the frosting and rounds out the flavors.
- Pecans: Adds a lovely crunch as well as a nutty flavor that perfectly complements the chocolatey goodness of the cake and frosting. Feel free to use additional pecans as a garnish or another nut of your choosing.

Storage Information
- Make Ahead: You can bake the cake a day in advance. Just keep it covered at room temperature.
- Storing Leftovers: Store leftover cake in an airtight container at room temperature for up to 3 days. If you prefer it chilled, refrigerate it, covered, for up to a week.

What’s the best way to serve this cake?
Mississippi Mud Cake is best served at room temperature, allowing the marshmallows to fully cool and for the frosting to set. It cannot be served hot straight out of the oven or you will end up with a goopy marshmallowy mess. This is perhaps the hardest part of making this cake – waiting for it to cool down! You can enjoy this cake on its own or with a scoop of vanilla ice cream for extra indulgence.
Variations to Try
- Skip the pecans in the frosting for a nut-free version. You can add some mini chocolate chips for extra texture instead.
- Mix in a handful of chocolate chips into the batter for an extra burst of chocolate in every bite.
- Enhance the chocolate flavor by substituting the boiling water with hot brewed coffee.
- Don’t love pecans? No problem. Walnuts, almonds or pistachios would all be excellent choices.
Frequently Asked Questions
Can I use a different size pan?
Yes! You can use two 9-inch round pans. Just reduce the baking time by a few minutes and keep an eye on the cake.
Can I make this cake without marshmallows?
Absolutely! While the marshmallows add a gooey texture, you can skip them and still have a delicious chocolate cake with a rich, velvety frosting.
Do I have to use pecans?
Not at all! Feel free to swap the pecans for walnuts, almonds, cashews or pistachios or skip them entirely if you prefer a nut-free dessert.
