Brooklyn Blackout Semifreddo Cake
I entered this cake in a recipe contest at Food52, we had to create a frozen dessert. I am a real lover of chocolate so I satisfied my craving with this cake. I am honored that my recipe was tested and photographed by the editors at Food52 and the beautiful photograph below was taken by James Ransom. I received a Community Pick!!
Who doesn’t love a Brooklyn Blackout Cake, the iconic cake that became the official cake of Brooklyn, made famous by it’s creators at Ebingers Bakery. Three layers of chocolate cake filled with chocolate pudding, frosted with the pudding and cake crumbs pressed on the side of the cake. This is a frozen version of this famous cake, 3 layers of chocolate sponge cake, chocolate semifreddo,chocolate ganache and cake crumbs. I made a chocolate sponge but you can use whatever type of cake you want or even cookie crumbs, this particular cake recipe freezes really well. I used my new favorite brand of chocolate for this cake, Divine (fair trade) chocolate, both the cocoa powder and the bar chocolate. It’s wonderful and I can’t say enough about the quality. Love it!
Makes 1 large loaf cake
Cake and Semifreddo:
- 1/4 cup milk
- 2 tablespoons unsalted butter
- 8 large eggs at room temperature
- 2 cups sugar
- 3/4 cups flour
- 1/2 cup unsweetened cocoa powder
- 1 teaspoon baking powder
- 1 teaspoon salt
- 1 teaspoon vanilla
- 7 ounces dark chocolate
- 2 teaspoons espresso powder
- 1 1/3 cup heavy cream (Optional)
- 2 tablespoons softened cream cheese
- 2 large eggs
- 1/2 cup sugar
- 2 teaspoons vanilla
- Pre heat oven to 350 degrees. Place milk and butter in glass measuring cup and microwave for 45 seconds or until butter is melted. Using stand mixer with wire whisk or electric mixer whip the eggs and sugar on med/high for approximately 8 minutes or until the mixture is pale yellow, tripled in volume and thick, with the machine running slowly add the heated milk and butter. Sift the flour, cocoa, baking powder and salt. Fold into the egg mixture, there should be no lumps. Fold in the vanilla. Grease a 1/2 sheet pan, lay parchment sheet and grease the parchment, and sprinkle with sugar. Pour batter into the pan, spread so that it is evenly distributed and bake for 20-25 minutes. Allow to cool for a couple of minutes in the pan run a knife around the edges to loosen then invert onto wire rack, remove parchment and let cool completely.
- In a bowl over a pot of simmering water (or in the microwave at high heat stirring every 30 seconds), melt chocolate and espresso powder and set aside. Keep pot of water simmering on the stove – you’ll use it again. Whip cream and cream cheese to soft peaks and store in fridge until ready to use. Whisk together eggs, sugar, and vanilla in a metal or glass bowl. Place bowl over simmering water and whisk until it thickens and sugar is melted, remove from simmering water and whisk constantly until doubled in volume, and whisk leaves a ribbon when lifted from bowl. Whisk in melted chocolate and allow mixture to cool for about 10 minutes, you don’t want to melt the whipped cream. Meanwhile, line a loaf pan with plastic wrap. Fold whipped cream into chocolate mixture, in two additions, until evenly incorporated.
Ganache and assembling:
- 4 ounces dark chocolate broken into small pieces
- 1/4 cup +2 tbs heavy cream
- 1 tablespoon corn syrup (optional)
- Heat milk until scalding, add chocolate and corn syrup to hot cream, let sit for approximately 5 minutes, stir until smooth. Let cool at room temperature.
- Line loaf pan with plastic wrap (I like to spray the bottom and sides with cooking spray before I lay the sheet of plastic. Take your cooled cake and cut 3 pieces that will fit in your loaf pan, lay one layer on the bottom pour half of the semifreddo on top, add another layer of cake, pour on the rest of the semifreddo, top with another layer of cake. Save the leftover cake you will need it for the crumb layer. Wrap well with plastic wrap and let freeze overnight.
- Crumble the leftover cake and set aside, I pulsed a couple of time in the processor. Remove cake from loaf pan, all you have to do is lift out the plastic if it won’t come out just quickly dip pan in some warm water. place on serving dish and remove plastic. Spread a thin layer of ganache on the sides of cake, press crumbs on sides, spread ganache on top of cake and freeze until ready to serve.
