This fun devil's food cake is covered in marshmallow frosting. It's topped with cake crumbs and tastes better after the first day.

½cupunsweetened cocoa powder
3large eggsroom temperature
2ouncesbittersweet chocolatemelted and cooled
½cupbuttermilk or whole milkroom temperature
4ouncessemi-sweet or milk chocolatefinely chopped (can substitute with ⅔ cup of mini chocolate chips)
Filling and frosting
½cupegg whitesfrom ~4 large eggs
¾teaspooncream of tartar
Bake the cake
Preheat your oven to 350° F. Generously grease and line two 8-inch round baking pans with parchment paper and set aside.
In a large bowl, whisk together the flour, cocoa, baking soda, baking powder and salt. Set aside.
In the bowl of a stand mixer fitted with the paddle attachment or in a large bowl if using a handheld mixer, cream the butter on medium speed until light and fluffy, about 2-3 minutes. Add the sugars and beat for another 3 minutes.
Add the eggs one at a time until smooth. Add the vanilla. The batter may appear curdled - that is OK. Turn the mixer to low and add in the melted chocolate.
Alternatively add the dry ingredients and the buttermilk, beginning and ending with the dry ingredients. Mix until everything just comes together - do not over mix. The batter will resemble frosting.
With the mixer on low, slowly stream in the boiling water. This will thin out the batter. Fold in the chopped chocolate/chocolate chips.
Evenly distribute the batter into your prepared baking pans and bake in your preheated oven for 25-30 minutes or until a toothpick inserted in the center comes out clean.
Allow the cake to cool for about 5 minutes before removing from the pan and allowing to fully cool on a wire rack.
Make the filling/frosting
In the bowl of a spotlessly clean stand mixer fitted with the whisk attachment or in a large bowl if using a handheld mixer, add the egg whites. Set aside.
In a small saucepan, place the sugar, cream of tartar and water. Stir to combine. Turn on the stove to medium-high and allow the mixture to come to a boil. Watch it carefully. Once the mixture reaches 235° F, start beating your egg whites in the mixer. You'll want them to come to soft peaks. If they achieve firm peaks, turn the mixer down to low and wait for the syrup to continue heating. Allow the sugar syrup to reach 242° F.
Once the sugar syrup reaches 242° F, very carefully stream it into the mixer. Turn the mixer to high and then add the vanilla extract. Your final frosting should be smooth, shiny and fluffy.
Assemble the cake
Cut each cake layer in half horizontally. Put one layer off to the side and crumble it. Place one cake layer (preferably a "bottom" layer) on a cake stand or plate. Top with a layer of the marshmallow frosting. Then add a layer of cake on top. Add some frosting on top of that and then the third layer of cake.
Frost the top and sides of the cake with the remaining frosting. Take the cake crumbles (from the 4th layer of cake) and apply it to the top and sides of the cake.
Refrigerate the cake for at least 1 hour before serving. The cake is actually best a day after it's made.
Slice and enjoy.
Leftover cake should be covered and stored in the refrigerator. It will last for several days.Source: Baking: From My Home to Yours by Dorie Greenspan
