Chocolate And Vanilla Layer Cake Recipes

Steps:

• Make the cake: Preheat the oven to 350˚ F. Butter and flour two 9-inch round cake pans and line the bottoms with parchment paper. Put the cocoa powder and chocolate in a medium bowl. Add the boiling water and whisk until the chocolate is melted. Whisk in the sour cream until smooth; let cool to room temperature.
• Whisk the flour, baking soda and salt in a medium bowl; set aside. Beat the butter, granulated sugar and brown sugar in a large bowl with a mixer on medium-high speed until fluffy, 3 to 4 minutes. Add the eggs, one at a time, then the vanilla, beating well after each addition. Reduce the mixer speed to low. Beat in the flour mixture in 3 additions, alternating with the cocoa mixture in 2 additions. Finish mixing gently with a rubber spatula, scraping the bottom and sides of the bowl.
• Divide the batter evenly between the cake pans. Tap the pans against the counter to eliminate any air bubbles. Bake until the cakes spring back in the center when gently pressed, 35 to 40 minutes. Let the cakes cool in the pans for 10 minutes, then run an offset spatula around the edges and turn out the cakes onto a rack to cool completely. Remove the parchment.
• Make the frosting: Bring a few inches of water to a simmer in a medium saucepan over medium heat. Whisk the egg whites, granulated sugar and salt in the bowl of a stand mixer. Set the bowl over the saucepan (do not let the bottom of the bowl touch the water); cook, whisking, until the sugar dissolves, the egg whites are frothy and the mixture is warm, 3 to 5 minutes.
• Transfer the bowl to the stand mixer and beat with the whisk attachment on medium-high speed until stiff glossy peaks form and the mixture cools to room temperature, about 5 minutes. With the mixer running, add the butter a few pieces at a time, waiting for them to incorporate before adding more. (The mixture will become liquidy, then it will get thick and shiny once the butter emulsifies. It may also look curdled as you add the butter. It's OK: Keep adding butter and beating.) Add the vanilla and beat until combined and fluffy, 3 to 5 more minutes.
• Cut each cake in half horizontally to create 4 layers. Place 1 layer on a cake stand or serving plate. Spread about 2/3 cup frosting on top, then repeat with the remaining cake layers, spreading more frosting in between them. Spread a thin layer of frosting on the top and sides of the cake (this is the crumb coat - it doesn't have to be perfect), then refrigerate until the frosting sets, about 30 minutes. Spread the remaining frosting all over the top and sides of the cake, smoothing it with a bench scraper.
• Make the ganache: Heat the heavy cream in a saucepan over medium-high heat until steaming, then pour over the chocolate in a small heatproof bowl. Let sit for 5 minutes, then stir until smooth. Set aside until cool but still pourable, 20 to 40 minutes (the time will vary depending on the temperature and bowl). Pour the ganache on top of the cake and spread with a small offset spatula, letting it drip down the sides. Let the ganache set 20 to 30 minutes before slicing.

Steps:

• Pre heat the oven to 180c/160c fan/gas mark 4 and grease two round cake tins.
• Mix together the flour, baking powder and sugar in a large bowl. Add the eggs, butter, vanilla extract and milk and combine.
• Separate the mixture into two bowls, in one of the bowls add the cocoa powder and blend, if you've added enough milk to the mixture initially the cocoa should blend perfectly to a smooth consistency.
• Pour each mixture into the tins so you'll have a tasty chocolate layer in one and a tasty vanilla layer in the other. Bake for 20 minutes or until a skewer comes out clean then leave to cool in the tins for 10 minutes before removing and cooling the cake.
• Whilst the cake halves are cooling make your buttercream, mix the butter with half of the icing to a creamy mixture, then add the rest of the icing sugar and mix. Meanwhile melt the white chocolate, then add this into the buttercream and beat, if you want to add a bit of colour to your buttercream at this point add some food colouring and mix.
• Place the bottom half of your cake onto a plate and spread half of the buttercream on top, place the other cake half on top and spread the remaining buttercream on top and if desired on the sides.
