When I think of a chocolate lover’s dream, this is the cake that comes to mind! It’s called a “Mississippi Mud” cake because of the layers of soft marshmallow and chocolate that make up the topping and frosting. It’s one of the easiest cakes to make, baked in a simple 9×13” pan. I adapted the recipe from my favorite Hershey’s Perfectly Chocolate Cake recipe but instead of buttermilk I used milk and sour cream for an extra moist and tender cake. The warm chocolate frosting is the same recipe I use for this popular Texas Sheet Cake. It’s SO GOOD!
How to Make Mississippi Mud Cake:
Combine dry ingredients: flour, sugars, cocoa powder, baking powder, baking soda and salt.Add wet ingredients: Add oil, eggs, vanilla, milk and sour cream and mix until combined. Reduce speed and carefully pour in the boiling water. Beat on high speed for 1 minute to add air to the batter.Bake: Pour batter into greased 9×13” pan and bake for 28-33 minutes.Add marshmallows. Remove cake from oven and sprinkle marshmallows all over the top of the hot cake, completely covering it. Return to oven for 2-3 minutes until marshmallows are puffed up. Cool cake before frosting. Make the Frosting: Melt butter in a small saucepan over medium-high heat. Add milk and cocoa powder and whisk well. Cook for about 2-3 more minutes, stirring constantly. Remove from heat and stir in vanilla and powdered sugar. Use an electric mixer to make the frosting smooth.Drizzle frosting over cake.
Make Ahead and Freezing Instructions:
The cake can be made 1-2 days in advance, stored covered at room temperature or in the refrigerator. The baked and frosted cake can be frozen for up to 3 months.
