Ingredients For Your Mississippi Mud Cake Recipe

I’ve noted this important baking tip many times, but it bears repeating for an exceptional, fudgy chocolate mud cake! To avoid an undercooked center and overcooked edges, use ingredients at room temperature for even baking (unless the recipe specifies otherwise).

For specific amounts, please refer to the printable recipe card at the bottom of the post.

Chocolate Mud Cake:

• Unsalted Butter – adds depth to a Mississippi mud cake and a firmer crumb(see Notes & Tips below).
• Sugar – white granulated
• Large Eggs – act as a binder and provide moisture to mud cake. The chill must be off the eggs before creaming them with sugar. 
• Vanilla Extract – For the best flavor, use real vanilla extract. You can even make your own vanilla extract; you’ll be glad you did!
• All-Purpose Flour – (187.5 G) If you don’t have a kitchen scale, do not compress flour by scooping it into the measuring cup. Use the fluff, spoon, and level method.
• Unsweetened Cocoa Powder – Usually, Dutched (alkalized) cocoa powder is used with recipes using baking powder as leavening. The alkalizing process neutralizes the acidity* of cocoa powder: it’s less bitter, darker in color, and brings forward more chocolate flavor. 
• Baking Powder -make sure it’s fresh. (see tip below)
• Salt
• Pecans – raw or lightly toasted and chopped.
• Coconut – sweetened or unsweetened shredded coconut.
• Marshmallow Cream – a large-sized jar. Jet-Puffed Marshmallow Creme or Marshmallow Fluff is easy to find at your local grocer.

TIP: You can test your baking powder for freshness. Simply, pour a little baking powder into hot water — if it fizzes, it’s still good to use!

Frosting For Mississippi Mud Cake:

• Powdered Sugar
• Softened Butter 
• Evaporated Milk
• Unsweetened Cocoa Powder
• Vanilla Extract
• Chopped Pecans

Directions For Mississippi Mud Cake

Preheat oven to 350° F. Grease a 9×13-inch baking dish with baking spray and set aside. You’ll need a couple of mixing bowls, an electric mixer, a spatula, and the willpower not to swipe a finger through all that glorious chocolate mud cake batter!

When you are making this recipe, you’ll want to use the full recipe at the bottom of the page.

1. Beat butter and sugar until creamy; add eggs and vanilla and beat well.
2. Combine dry ingredients in a separate bowl.
3. Mix the wet and dry mud cake ingredients until just combined.
4. Bake in the center of the oven until the center is springy. 
5. Soften spoonfuls of marshmallow creme on warm cake and spread; allow to cool completely.

Mississippi Mud Cake Frosting Directions:

1. Cream butter and powdered sugar until light and fluffy. 
2. Mix in milk, cocoa powder, and vanilla; fold in nuts.
3. Spread Mississippi mud cake frosting over the marshmallow fluff layer. 
4. Chill the cake for 10-15 minutes before serving.

DYK? Unless otherwise noted, baking ingredients like eggs, milk, and butter, should always be at room temperature before being incorporated into a batter or dough. Recipes typically assume that ingredients are at room temperature before the batter is placed in the oven at a specific temperature for a certain amount of time. This ensures even baking, especially for treats like this mud cake recipe.

Recipe Notes/Tips

• Using a kitchen scale can significantly impact the outcome when measuring flour and powdered sugar for baked goods.
• You can choose between butter and vegetable oil in a cake recipe based on flavor preferences, as butter adds rich flavor while oil remains neutral in taste. Additionally, using oil typically yields a moister crumb, while butter contributes to a more structured texture in the cake.
• If you use mini marshmallows instead of marshmallow creme, cover the chocolate mud cake with them until softened. Briefly set the mud cake under the broiler until the marshmallow peaks lightly caramelize to a golden yellow.
• Marshmallow Fluff is quite a bit thicker (see FAQ) than Kraft’s Jet-Puffed Marshmallow Creme and is usually a bit less expensive per ounce. 
• Cover the cake with plastic wrap while it chills to keep it moist and prevent the frosting from drying or becoming crusted.

How To Store This Recipe

A mud cake will keep at room temperature for up to five days;* keep it covered so it won’t dry out. If you want it to last longer, wrap it tightly and refrigerate.

Note:* I’ve read claims that Mississippi mud cake can last a week to ten days on the counter and up to three weeks in the fridge if wrapped really well. That has never been put to the test around here, for obvious reasons… it’s gone!

Freeze Mud Cake

It is widely agreed that Mississippi mud cake is a great option for freezing, especially leftovers. If only two of you are in the household, portion leftover cake into double servings, wrap it tightly in plastic, followed by foil, and put them into a freezer bag or other airtight container. If wrapped to avoid freezer burn, mud cake can last over three months. Thaw for several hours in the fridge or overnight.
