Mississippi Mud Cake
Mississippi Mud Cake is a rich Southern dessert with fudgy chocolate cake, gooey marshmallows, and a smooth chocolate icing on top.
- 1¼ cups unsalted butter
- 1½ cups granulated sugar
- 1½ cups all-purpose flour
- 1 cup cocoa powder
- 4 large eggs
- 2 tsp vanilla extract
- 1 cup chopped pecans
- 4 cups mini marshmallows
- 16 ounces confectioners' sugar
- ½ cup whole milk
Set the oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or nonstick spray and set aside.
In a large bowl, cream the softened butter and sugar until fluffy. Beat in the eggs one at a time. Mix in the flour and cocoa powder until combined. Stir in vanilla, then fold in chopped pecans.
Pour the batter into the dish and smooth the top. Bake for 25 minutes, or until a toothpick comes out with a few moist crumbs.
Remove from oven and immediately sprinkle marshmallows evenly over the cake. Let sit for 5 minutes to soften, then gently spread into an even layer.
Whisk together confectioners' sugar and cocoa powder in a bowl. Add softened butter and gradually whisk in milk until smooth and pourable.
Pour icing over the softened marshmallow layer and spread evenly. Let the cake cool completely before slicing.
