White Chocolate Cake With Raspberry And Chocolate Ganache Fillings And Buttercream Icing Recipes

Steps:

• Preheat the oven to 300 degrees F (150 degrees C).
• Combine chopped chocolate and hot coffee in a bowl. Stir occasionally until chocolate is melted and mixture is smooth. Set aside.
• Sift sugar, flour, cocoa powder, baking soda, baking powder, and salt together in a large bowl.
• Beat eggs in a bowl using an electric mixer until slightly thickened and lemon-colored. Slowly add oil, buttermilk, vanilla extract, and melted chocolate mixture. Beat until well combined. Add sugar-flour mixture; beat on medium speed until just combined. Divide batter between the prepared cake pans.
• Bake in the preheated oven until a toothpick inserted into the center comes out clean, 1 hour to 1 hour and 10 minutes. Let cool completely in pans on wire racks, about 30 minutes. Invert layers onto racks.
• While cakes are cooling, bring heavy cream, sugar, and corn syrup to a boil over low heat in a small saucepan. Whisk until sugar dissolves. Add chocolate; whisk until melted. Add butter; whisk until smooth. Let ganache frosting cool until spreadable, about 10 minutes.
• While frosting and cakes continue to cool, puree raspberries in a food processor. Press through a fine mesh strainer with the back of a spoon into a saucepan. Pour in sugar and cornstarch; bring to a boil over medium-low heat. Cook until thickened and reduced, 5 to 7 minutes. Stir in lemon zest. Remove raspberry filling from heat.
• Cut each cake layer in 1/2 horizontally to produce 4 equal layers. Spread 1/3 raspberry filling onto each of 3 layers and stack. Place top layer onto cake. Spread ganache frosting evenly from center of top layer down the sides of the cake.

Steps:

• Heat oven to 180C/160C fan/gas 4. Grease and line the base of 2 x 20cm round, loose-bottomed cake tins. Put the butter and chocolate in a heatproof mixing bowl, set over a pan of barely simmering water and allow to melt slowly, stirring occasionally.
• When the butter and chocolate have melted, remove from the heat and allow to cool for 1-2 mins, then beat in the eggs and sugar with an electric whisk. Fold in the flour and raspberries.
• Gently pour the mixture into the tins and bake for 20-25 mins or until golden brown and a skewer inserted into the centre comes out clean (the raspberries may leave a residue on the skewer, so don't be fooled by their juiciness). Remove the cakes from the oven and allow to cool in the tins for 10 mins before turning out onto a wire rack.
• To make the ganache, put the chocolate in a heatproof bowl with 100ml of the cream, set over a pan of barely simmering water. Stir until the chocolate has melted into the cream and you are left with a smooth, glossy ganache. Leave the ganache to cool to room temperature, then beat in the rest of the cream.
• When the cakes have cooled, sandwich them together with the chocolate ganache. Dust with icing sugar just before serving.

Steps:

• Heat the oven to 180C/160C fan/gas 4. Butter three 18cm sandwich cake tins and line with baking parchment. Beat together the butter, sugar, eggs, vanilla, baking powder and flour using a stand mixer or electric hand whisk until you have a fluffy mixture, about 5 mins. Fold in the white chocolate until it's well distributed throughout.
• Divide the mixture evenly between the tins and level out using a palette knife or the back of a spoon until smooth. Bake for 25-30 mins until a skewer inserted into the middle comes out clean. Remove from the oven and leave the sponges to cool in the tins for 10 mins, then remove from the tins and transfer to a cooling rack, top side down, and leave to cool completely. If the sponges are not level use a serrated knife to cut away the peaks.
• While the sponges are cooling, make the ganache. Put the white chocolate in a large bowl. Pour the cream into a saucepan over a medium heat and bring to a simmer. Immediately pour the cream over the chocolate and leave to stand for 4-5 mins until the chocolate has melted. Mix together to form a smooth ganache, ensuring all the chocolate has fully melted, then mix in the vanilla. Chill in the fridge for 30 mins, stirring occasionally so it doesn't completely harden, until spreadable and thick enough to coat the cake.
• Once the sponges are cool and the ganache has set to a spreadable consistency, you can construct the cake. Place one sponge on a serving plate, spread over a thin layer of the chocolate ganache, then fill the middle with a third of the raspberries. Place another sponge on top and repeat with a layer of ganache and another third of raspberries. Put the final sponge on top and gently coat the whole cake with a thin layer of ganache. Leave in the fridge to set for at least 20 mins. To finish, spread over any remaining ganache and top with the remaining raspberries. Will keep chilled for up to three days in an airtight container.
