Brooklyn Blackout Cake Recipes

BROOKLYN BLACKOUT CAKE

Steps:

• Make the custard first as it needs to chill. Put all the ingredients, except the vanilla, in a large pan and bring gently to the boil, whisking all the time, until the chocolate has melted and you have a silky, thick custard. It will take 5-7 mins from cold. Stir in the vanilla and a generous pinch of salt, then scrape the custard into a wide, shallow bowl. Cover the surface with cling film, cool, then chill for at least 3 hrs or until cold and set.
• Heat oven to 180C/160C fan/gas 4. Grease then line the bases of 2 x 20cm sandwich tins. Melt the butter in a pan, then remove from the heat and beat in the oil, buttermilk, coffee and eggs. In a large bowl, whisk the dry ingredients togetherplus 1/4 tsp salt (saves sifting) and squish any resistant lumps of sugar with your fingers. Tip in the wet ingredients and whisk until smooth.
• Divide the batter between the prepared tins and bake for 25-30 mins until risen and a skewer inserted into the middle of the cakes comes out clean. Cool for 10 mins, then transfer to a rack to cool completely, parchment-side down.
• Remove the parchment linings from the cakes. If the cakes are domed, trim them flat. Now cut each cake across the middle using a large serrated knife. Put your least successful layer and any trimmings into a processor and pulse it to crumbs. Tip into a large bowl.
• Sit one layer on a cake plate and spread it with a quarter of the custard. Sandwich the next layer on top, add another quarter of the custard, then top with the final layer of cake. Spoon the remaining custard on top of the cake, then spread it around the top and down the sides until smooth. Chill for 15 mins to firm up the custard again.
• Hold the cake over the bowl containing the crumbs, then sprinkle and gently press a layer of crumbs all over the cake. Brush any excess from the plate. You'll have some crumbs left. Chill for 2 hrs, or longer, before serving, and eat it cold. Can be made up to 2 days ahead. The cake gets fudgier and more enticing the longer you leave it.

THE BEST BROOKLYN BLACKOUT CUPCAKES

Steps:

• In a small, heavy bottomed saucepan, combine the cornstarch and both sugars. Gradually pour in the milk, adding it a little bit at a time, and whisking well to ensure no lumps form in the mixture.
• Cook over medium heat, stirring constantly, until the mixture thickens and can coat the back of a spoon, about 10 minutes.
• Add the chopped chocolate and continue to cook, stirring often, for about 4 minutes, or until the pudding is smooth and very thick.
• Remove from heat and stir in the vanilla. Pass the mixture through a fine-mesh strainer into a large serving bowl.
• Place plastic wrap on top of the pudding and smooth it gently against the surface. Refrigerate for at least 2 hours, or up to 3 days.
• Preheat oven to 350 degrees (F). Line (2) 12-cup muffin tins with cupcake liners. Spray lightly with non-stick baking spray, and set aside.
• In a large bowl, sift together the flour, cocoa powder, baking soda, baking powder, and salt. Set aside until needed.
• Combine the oil, butter, and chocolate together in a large bowl. Heat in the microwave, in 30 second increments, stirring between increments each time, until the butter and chocolate are completely melted. Stir in the espresso powder. Set aside and cool while you assemble the other ingredients.
• In a large bowl, combine both sugars, eggs, egg yolk, and vanilla and beat until smooth and well combined.
• Gradually add in the melted chocolate mixture, adding a little bit at a time and whisking constantly.
• Gently fold in the flour in 3 additions, alternating with the sour cream, beginning and ending with the flour. Mix gently and stop when you can still see the lightest trail of dry ingredients.
• Pour in the hot coffee (or water) and let it sit for 30 seconds, then fold it into the batter until combined.
• Fill each cupcake liner so that they're 2/3 full with batter. Bake, one tray at a time, for 16 to 18 minutes, or until the cupcakes have puffed up and a toothpick (or cake tester) inserted in the middle of a cupcake comes out clean, or with a few moist crumbs attached.
• Allow cupcakes to cool completely before frosting!
• Place both chocolates in a microwave-safe bowl. Heat in the microwave, on low power, in 30 second increments, stirring between each increment, until the chocolate is completely smooth and melted. You may also do this in a double-boiler. Set aside and cool until tepid.
• In the bowl of a stand mixer fitted with the paddle attachment or in a large bowl using a handheld electric mixer, beat the butter until completely smooth.
• On low speed, add in the confectioners' sugar, a little bit at a time, beating until each addition has been completely incorporated into the butter before adding more. Once all of the sugar has been added, increase speed to medium-high and beat for 3 minutes.
• Decrease the speed back to low and beat in the vanilla extract. Then slowly pour in the cooled melted chocolate and continue mixing until well combined, tuning the mixer off and scraping down the sides and bottom of the bowl as needed.
• Once all of the chocolate has been added, increase the speed back to medium-high and beat for 2 minutes. Set aside for 30 minutes to firm up, or up to 3 hours. Do not refrigerate (the chocolate will seize and render the frosting impossible to spread).
• Using a paring knife, cut out a 1/2" inch cone shaped hole in the middle of each cooled cupcake. The hole should stop about 1/4" from the bottom of the cupcake, to avoid breaking the base. Set all of the cupcake scraps aside!
• Scrape the chilled pudding into a large piping bag fitted with a medium piping tip, like this one.
• Pipe the filling into the middle of each cupcake cavity, filling it all the way to the top.
• Next, scrape your fudgy chocolate frosting into a piping bag fitted with an open star piping tip, like this one. Pipe the frosting on top of each cupcake, making sure the pudding is completely covered.
• Crumble up the cupcake scraps into fine crumbs and sprinkle a generous amount on top of each cupcake.
• Serve at once, or store in the fridge until needed. Cupcakes are best served the day they are made, but will keep, stored in the fridge, for 2 days.

BLACKOUT CAKE

Steps:

• To make the Chocolate Pudding: Combine 1 cup milk with 2 tablespoons sugar in a small saucepan and bring to just under a boil.
• In a mixing bowl, combine remaining sugar with salt, cocoa, and cornstarch. Whisk in remaining 1/2 cup unheated milk. Gradually whisk in hot milk and place entire mixture back into the saucepan. Heat, over medium heat, stirring, until mixture thickens and just starts to bubble.
• Whisk in egg and egg yolk and cook, stirring, for 30 seconds. Remove from the heat and whisk in chopped chocolate and butter. When both are melted, strain pudding through a fine-mesh strainer, and cool. Cover with plastic and reserve in refrigerator.
• To make the Cake: Preheat oven to 350 degrees F. Lightly butter 2 (8-inch) cake pans and line with parchment. Butter the parchment and flour pans, shaking out the excess.
• Sift together flour, cocoa, baking soda, baking powder, and salt. Reserve.
• In a mixer with a whip attachment, beat eggs and sugar until thick and lemon-colored. Beat in vegetable oil. Alternately add dry ingredients with buttermilk, scraping the bowl once or twice. Add the coffee and vanilla to form a thin batter. Divide between prepared cake pans.
• Bake until a toothpick inserted in the center of a cake comes out clean, about 40 to 45 minutes. Cool in pan for 15 minutes. Invert onto cooling racks, peel off paper and cool completely.
• When cool, split each cake in half with a serrated slicing knife. Reserve 1 layer for another use. Spread bottom layer with half of the reserved Chocolate Pudding. Place second layer on top and spread with remaining pudding. Top with last cake layer.
• To make the Icing: Over a double boiler, melt chocolate with butter. Remove from heat, whisk in brewed coffee, corn syrup, and vanilla. Place icing over an ice bath and chill, whisking often until the mixture is of soft but a spreadable consistency. Working quickly, ice the sides and top of cake.
• In a food processor, pulse the cookies into crumbs. Press the crumbs onto sides and top of cake.
• Serve cake at room temperature. If holding for more than 2 hours, store in refrigerator for up to 48 hours, but bring to room temperature before serving.

BROOKLYN BLACKOUT CAKE

Steps:

• Preheat the oven to 375 degrees.
• Butter and flour 2 (9-inch) cake pans. Cut 2 circles of parchment paper or waxed paper to fit the bottoms of the pans, then press them in. In a mixer fitted with a whisk attachment (or using a hand mixer), cream the butter and shortening together. Add the sugar and mix until light and fluffy. One by one, add the eggs, mixing after each addition. With the mixer running at low speed, add the vanilla, cocoa, baking powder, baking soda, and salt and mix. With the mixer still running at low speed, add about 1/3 of the cake flour, then about 1/3 of the milk, and mix. Repeat with the remaining cake flour and milk and mix. Pour into the prepared pans and bake until dry and springy to the touch and a tester inserted into the center comes out clean (a few crumbs are okay), 30 to 35 minutes. Let cool in the pan for 15 minutes, then turn out onto wire racks and let cool completely, to room temperature. Using a long serrated knife, cut the cake layers in half horizontally. Reserving 3 halves for the cake, put the remaining half in a food processor, breaking it up with your hands. Pulse into fine crumbs.
• To finish the cake, place a cake layer on a cake plate or serving platter (reserving the most even layer for the top) and spread with cooled custard. Top with another layer of cake, then custard, then the final layer of cake. Cover the top and sides of the cake with the remaining custard. Coat the cake with the cake crumbs. Chill until ready to serve, at least 2 hours. Serve the same day.
• Pour 2 1/2 cups of the water, the sugar, corn syrup and cocoa powder into a large non-reactive saucepan and bring to a boil over medium-high heat, whisking occasionally. Meanwhile, in a small bowl, whisk the remaining 1/2 cup of water and the cornstarch. Whisk into the cocoa mixture in the saucepan and return the mixture to a boil, whisking constantly. Cook, whisking constantly, until very thick, 3 to 4 minutes. Remove from the heat and stir in the butter and vanilla. Pour into a bowl. Cover with plastic wrap, lightly pressing the plastic against the surface to prevent a skin from forming. Chill until firm, about 45 minutes.
