Decadent Mississippi Mud Cake

Follow our step-by-step guide on how to make Decadent Mississippi Mud Cake.

1. Step 1

   Start by preheating your oven to a cozy 350°F (175°C). Grab a 9x13-inch baking pan and give it a good greasing and flouring to ensure your cake slides out easily later on.

2. Step 2

   In a large mixing bowl, combine the white sugar, all-purpose flour, and salt. Give it a good stir to mix everything together.

3. Step 3

   In a saucepan, melt together the unsalted butter, vegetable oil, cocoa powder, and water over medium heat. Bring this mixture to a gentle boil, stirring until it's smooth and well combined. Once it's ready, remove it from the heat and pour it into the flour mixture, stirring until just combined.

4. Step 4

   In a separate bowl, whisk together the buttermilk, eggs, vanilla extract, and baking soda. Pour this mixture into the chocolate batter and mix until everything is beautifully blended. Now, pour the luscious batter into your prepared baking pan, spreading it evenly.

5. Step 5

   Bake in your preheated oven for about 25 minutes, or until a toothpick inserted into the center comes out clean. Once baked, let the cake cool slightly in the pan.

6. Step 6

   For the icing, combine the remaining butter, milk, and cocoa powder in a saucepan. Bring this to a boil, then remove it from the heat. Whisk in the confectioners' sugar and the remaining vanilla extract until smooth. If you like a little crunch, fold in some chopped pecans for added texture.

7. Step 7

   Once your cake has cooled a bit, sprinkle marshmallows over the top, then pour the warm icing over the marshmallows, allowing it to seep in. Let the cake cool completely before slicing into it and serving. Enjoy this delightful treat with friends and family!
