How to make Mississippi Mud Sheet Cake
Step 1: Prepare the oven. Preheat it to 350 degrees F. Using butter or nonstick spray, grease a 9 x 13-inch baking dish.
Step 2: Place the eggs in a large bowl. Using an electric mixer, beat the eggs until thick. Then, add the sugar and vanilla. Beat again until blended.
Step 3: Place the melted butter, flour, cocoa, salt, coconut, and pecans in another bowl. Mix well until combined. Then, add this to the egg mixture and stir well until blended.
Step 4: Into the prepared pan, pour the batter. Place in the preheated oven and bake for about 25 to 28 minutes or until a toothpick inserted in the middle of the cake comes out clean.
Step 5: While the cake is baking, prepare the frosting. Place the melted butter and cocoa powder in a clean bowl. Mix well, then add the vanilla along with 2 c powdered sugar. Mix again until well incorporated. Next, add the half-and-half followed by the rest of the 2 c powdered sugar. Mix until smooth, adding extra milk until you reach your preferred consistency.
Step 6: Take the cake out of the oven when done and spread with the marshmallow creme on top. On top of the marshmallow creme, spread the frosting using a spatula or knife.
