Fun Bakery - Chocolate Devil's Layer Cake w/ Marshmallow Frosting

I have not baked for soooo long, long enough to forget which cake I did bake last time.

Ummm..

Last Sat, it was the big day of my best frd, Ah Goo. I finally decided to make him a cake for his party. Thus, here comes the Chocolate Devil’s Layer Cake with Marshmallow Frosting!!!

Ingredients :
- 3 cups cake flour
- 2 teaspoons baking powder
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 cup boiling water
- 3/4 cup Dutch-processed cocoa powder
- 3 sticks unsalted butter, softened
- 2 cups packed light brown sugar
- 4 large eggs, room temperature
- 1 cup plain yogurt, room temperature
- 1 tablespoon vanilla extract

Marshmallow Frosting
- 1.5 cups sugar
- 6 large egg whites
-2 teaspoons vanilla extract
- 2 tablespoons water

Directions:
Preheat oven to 350F. Grease three 9-inch round cake pans, and line the bottoms with parchment paper.

In a large bowl, whisk the flour, baking powder, baking soda and salt.

In another bowl, whisk the boiling water and cocoa powder until smooth.

Beat butter and sugar together on medium speed in a bowl of a standing mixer until light and fluffy. Beat in eggs, one at a time. Beat in buttermilk and vanilla extract.

Reduce the speed to low and beat in 1/3 of the flour mixture, followed by half of the chocolate mixture. Repeat with another 1/3 of the flour mixture and the remaining chocolate mixture.

Beat in the remaining flour mixture until just incorporated.

Divide the batter and pour into the prepared pans, smoothing the surface with a spatula. Bake 20 to 25 minutes or until a toothpick inserted into the cake comes out clean.

Place the cakes (in the pans) on a wire rack to cool. Then invert the cakes onto a greased rack. Cool completely before frosting.

To prepare frosting, in a large heatproof bowl, combine sugar and egg whites. Using a handheld electric mixer, beat on high speed until foamy for 1 minute. Set bowl over a pan of barely simmering water. Beat on high speed until frosting form stiff peaks, about 10 minutes.
Remove from heat, stir in vanilla and water, and beat for another 2 minutes until frosting thickens.

To assemble the cake, place one cake layer on your serving plate and spread with 1/3 cup frosting. Place another cake layer on top, and gently press down a little bit. Spread with another 1/3 cup frosting. Place the last layer of cake on top, smear the remaining frosting on the top and sides of the cake.

Leave it at room temperature and serve the cake in the same day, as over time the frosting will become grainy.
