Chocolate Cake with Chocolate Buttercream and a Crown of Whipped Cream Rosettes
A two-layer cake with thick chocolate buttercream all around, topped with a white crown of whipped cream and mascarpone rosettes. Hot coffee in the batter deepens the chocolate without tasting of coffee.
Preheat the oven to 175°C (345°F) and line two round pans 20 cm in diameter with parchment paper.
⚙ Preheating the OvenOven
💡Put things in the oven only once it's reached temperature, after the heating light has gone off: an oven that hasn't reached temperature changes baking times, and the bake burns outside or stays underbaked.
2
Sift the flour, cocoa, baking powder and baking soda into a bowl and add the sugar and salt.

3
Add the eggs, milk and oil and beat 2 minutes.

4
Add the boiling water and stir. The batter is thin, and that's fine.
💡The boiling water blooms the cocoa and deepens the flavor, and the thin batter makes an especially moist cake.
5
Divide between the pans and bake 30–35 minutes, until a toothpick inserted in the center comes out clean.

Whip the cold cream on medium speed, until it starts to thicken.

💡Cold cream whips quickly and holds firm: warm cream won't hold air. Stop when the peaks are firm, before it turns grainy.
💡Whip cream very cold, in a chilled bowl with chilled beaters, and stop when it holds firm: overwhipping turns it grainy and buttery.
8
Add the mascarpone and sugar and keep whipping on high speed to firm peaks.

Whip the soft butter on its own, until fluffy and pale.

💡Room-temperature butter whips into a smooth cream: cold butter stays lumpy, and melted butter won't hold the air.

Add the powdered sugar in two or three additions, then the milk, cocoa and melted chocolate, and keep whipping until the cream is smooth.

Place one cooled cake on a serving plate, spread a layer of frosting over it, set the other on top and coat the top and sides with the rest of the frosting.

Transfer the whipped cream to a piping bag with a star tip and pipe close rosettes in circles, from the edge inward, until the whole top is covered.
