Brooklyn Blackout Cake Recipes

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.

Steps:

• Whip together the heavy cream and confectioners' sugar in a large bowl with an electric mixer on medium-high speed until stiff peaks form, about 2 minutes. Fold in the pudding with a rubber spatula until well combined.
• Cut 6 squares of plastic wrap large enough to completely line each cup of a 6-cup jumbo muffin pan with a slight overhang at the top.
• Spread 1 heaping tablespoon of the pudding mixture in the bottom of each lined muffin cup. Break up 2 cookies and fit them into an even layer over the pudding. Repeat twice with the pudding and cookies until all of the muffin cups are full, ending with a cookie layer on the tops. Cover each cup with the overhanging plastic wrap. Refrigerate for at least 8 hours and up to 12. Reserve the remaining 6 cookies for garnish.
• When ready to serve, unwrap each cake and invert the muffin pan onto a large platter or cutting board all at once. Remove the plastic wrap. Transfer the individual cakes to serving plates. Crush the reserved cookies and sprinkle some on top of each cake, then drizzle with the chocolate syrup.

Steps:

• Heat the oven to 375 degrees.
• To make the cake, place the cocoa in a small bowl and whisk in the boiling water to form a paste. Combine the chocolate and milk in a saucepan over medium heat. Stir frequently as the mixture warms and the chocolate melts, about 3 minutes. Remove from heat. Whisk a small amount of the heated chocolate milk into the cocoa paste and then whisk the cocoa mixture into the milk mixture. Return to heat, stir for one minute, remove and cool until tepid.
• In the bowl of a mixer, cream the sugar and butter together. Beat in the egg yolks one at a time and add the vanilla. Slowly stir in the chocolate mixture.
• Combine the flour, baking powder, salt and baking soda. Using a spatula or a wooden spoon, slowly add the flour mixture to the chocolate mixture. In another bowl, whip the egg whites to form soft peaks and, using a rubber spatula, gently fold the egg whites into the batter.
• Butter and lightly flour two 8-inch round cake pans and divide the batter between the two pans. Bake for 45 minutes and cool on a rack for 15 minutes. Gently remove the cakes from the pans and continue to cool.
• While the cake is baking, make the filling. Put the cocoa into a saucepan and pour in the boiling water and place over low heat. Add the sugar and chocolate. Dissolve the cornstarch in the cold water to make a smooth paste. Whisk the cornstarch into the water and chocolate, add the salt and bring it to a boil, stirring constantly. Boil for one minute.
• Remove the pan from the heat, whisk in the vanilla and the butter, and transfer the mixture to a bowl and refrigerate until cool.
• Make the frosting. In a double boiler, melt the chocolate. Remove from heat and whisk in the butter, one tablespoon at a time, returning to heat if necessary to melt the butter.
• Whisk in the hot water all at once and stir until smooth. Whisk in the corn syrup and the vanilla. Refrigerate for 20 to 30 minutes before using.
• Assemble the cake. Use a sharp knife to slice each cake into two disks to form four layers. Set one layer aside. Place one layer on a cake round or plate. Generously swath the layer with filling. Add the second layer and repeat. Add the third layer. Quickly apply a layer of frosting to the top and the sides of the cake and refrigerate for 10 minutes. Meanwhile, crumble the remaining cake layer. Apply a second layer of frosting to the cake, press cake crumbs into the top and sides of the cake, and serve within 24 hours. Store in a cool place.

Steps:

• In a small heavy saucepan, mix sugar, cornstarch and salt. Whisk in milk. Cook and stir over medium heat until thickened and bubbly. Reduce heat to low; cook and stir 2 minutes longer. Stir in chocolate until melted. Transfer to a bowl; stir in vanilla. Cool slightly, stirring occasionally. Press plastic wrap onto surface of pudding. Refrigerate, covered, 2 hours or until cold., Preheat oven to 325°. Line bottoms of two greased 8-in. round baking pans with parchment; grease paper. In a small bowl, whisk flour, baking powder, baking soda and salt. In a large saucepan, melt butter over medium heat. Add cocoa; cook and stir until blended. Stir in sugars. Remove from heat; stir in buttermilk, coffee and vanilla. Whisk in eggs, one at a time, until blended. Stir in flour mixture just until combined., Transfer batter to prepared pans. Bake 35-40 minutes or until toothpick inserted in center comes out clean. Cool in pans 10 minutes before removing to wire racks; remove parchment. Cool completely., For frosting, in the top of a double boiler or a metal bowl over hot water, melt chocolate and butter; stir until smooth. Remove from heat. Whisk in hot water, all at once. Whisk in corn syrup and vanilla. Refrigerate 25-30 minutes or just until spreadable., Using a long serrated knife, cut each cake horizontally in half. Place a cake layer on a serving plate. Spread with half of the pudding. Repeat layers. Top with a third cake layer. Spread frosting over top and sides of cake., Crumble remaining cake layer; sprinkle over top and sides of cake, pressing lightly to adhere. Refrigerate leftovers.

Steps:

• Have ready 2 x 20 cm loose-bottom cake tins at least 5 cm deep.
• First make the filling as this requires a cooling time. Blend the cornflour with about a third of the 600 ml milk until smooth. Bring the remaining milk to the boil in a small nonstick saucepan with the 300 g sugar, syrup and 100 g cocoa, whisking until smooth. Add the cornflour solution, bring to the boil, stirring constantly, until you have a rich, thick custard. Remove from the heat and add the 1 teasp vanilla estract and 100 g butter, stirring until it melts. Ideally the mixture should be silky smooth but if not give it a quick whiz in a food processor. Pour into a large bowl, cover the surface with clingfilm, and set aside to cool completely.
• Preheat the oven to 190C/Gas 5 and butter the cake tins.
• For the cake mixture, cream the 180 g butter and 300 g sugar together in a food processor, then incorporate the eggs one at time, followed by the 1 teasp. vanilla extract, scraping down the sides of the bowl as necessary. Sift together the dry ingredients and add them half at a time to the creamed mixture, then add the 200 ml milk with the motor running.
• Divide the mixture evenly between the cake tins, weighting them for accuracy and smoothing the surface. Bake for 30-40 minutes until a skewer inserted at the centre comes out clean. Run knife around each cake and leave to cool.
• Remove the collars from the cakes and slit each one in half horizontally using a bread knife. Set aside the best-looking top half. Place the other top half in the food processor and whiz to crumbs.
• To assemble the cake, first give the chocolate-custard filling a stir. Spread a quarter of the filling over one cake base, taking it almost to the rim, place the other bace on top and spread with another quarter of the custard. Lay the reserved cake top in place. Coat the top and sides with the remaining custard.
• Coat all over the cake crumbs (this is the 'blackout'). When coating the sides, imagion you're making a sand castle, take handfuls of the crumbs and gently press them against the side, leaving any loose ones to fall down and discarding the excess. Chill for a couple of hours, then cover with clingfilm. Remove from the fridge 15-30 minutes before eating.

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 inches 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.
• Custard: 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.
• 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.
