Mississippi Mud Cake is one of my favorite southern sheet cakes. It’s a rich and moist chocolate cake covered with gooey marshmallows, crunchy pecans, and a fudge icing. Dessert doesn’t get any better than this.
Mississippi Mud Cake is one of the most popular potluck recipes. Everyone loves a good chocolate cake and this one is a real classic.
How To Make Mississippi Mud Cake
This recipe is wonderfully easy to make. You’ll begin by mixing the dry ingredients in a large bowl and then mix in the vegetable oil, eggs, milk, sour cream, and vanilla extract.
Next you’ll beat in 1 cup of boiling water. The purpose of the boiling water is to help hydrate the cocoa powder and prevent the cake from being dry. Bake the cake for about 30 minutes. Scatter the marshmallows on top and return to the oven for 2 minutes to partially melt the marshamllows.
Whip up the icing and drizzle it on the cake and finish with the pecans. Note: Leave the nuts off if you don’t like them.
Fudgy Icing
My favorite part of this cake? The fudgy icing. The icing is what gives the cake it’s name since it somewhat resembles the cracked mud along the edge of the Mississippi River.
Alot of Mississippi Mud Cakes have a really dense cake batter that’s almost like a brownie. This one isn’t quite that but it is still plenty chocolatey and rich. If you’re looking for something dense and fudgy, try these Peanut Butter Mississippi Mud Brownies. They are to die for!
Make Ahead and Storage
This easy sheet cake is perfect for making for a potluck. In all honestly, I think it tastes better the next day so it is great for making in advance. Can be stored at room temperature. Wrap it well so it doesn’t dry out.
