6 INCH LAYER CAKE RECIPES

Steps:

• 1. To make the lemon cake, preheat the oven to 350 degrees F. Butter the bottom and sides of two 9-inch round cake pans. Dust the pans with flour and tap out the excess.
• 2. In a medium bowl, sift together the flour, baking powder, baking soda, and salt. Stir together the dry ingredients with a whisk. Set aside.
• 3. In an electric stand mixer, using the paddle attachment or beaters, beat the butter on medium speed for about 30 seconds, or until creamy. Gradually add the sugar, increase the speed to medium-high, and continue to beat until the mixture is light, about 3 minutes. Scrape down the sides of the bowl.
• 4. Add the whole eggs and egg yolks, one at a time, beating well after each addition. Beat in the vanilla and lemon zest. Reduce the speed to low and gradually beat in he lemon juice (the batter will appear curdled at this point smooth out after you add the dry ingredients). Beat in the dry ingredients in 3 additions alternately with milk in 2 additions. Scrape down the sides of the bowl and beat for another 10 seconds. Scrape the batter into the prepared pans.
• 5. Bake the cakes for 20 to 25 minutes, or until a toothpick inserted into the center of each cake comes out clean. Cool the cakes in the pans on wire racks for 20 minutes. Invert the cakes onto the rakcs and cool completely.
• 6. To make the lemon filling, in a medium nonreactive saucepan, whisk together the yolks and sugar until combined. Whisk in the lemon juice, butter, and salt. Cook over medium-low heat, stirring constantly with a wooden spoon, for 5 to 6 minutes, or until the mixture turns opaque, thickens, and coats the back of the spoon. Do not let the filling boil, or it will curdle. Pour the mixture through a fine mesh sieve into a medium bowl. Stir in the lemon zest and allow the filling to cool.
• 7.Cover with plastic wrap, pressing directly onto the surface, and refrigerate for 1 hour, or until chilled.
• 8. In a clean bowl of the electric mixer, using the whisk attachment or beaters, beat the heavy cream on high speed until soft peaks form. Remove the lemon filling from the refrigerator and whisk until smooth. Using a rubber spatula, gently fold the whipped cream into the filling. Cover the bowl and refrigerate the filling until ready to assemble the cake.
• 9. To make the lemon frosting, in the large bowl of the electric mixer, using the paddle attachment or beaters, beat the butter on medium speed until creamy, about 30 seconds. Gradually beat in the confectioners' sugar on low speed. Add the cream, lemon juice, vanilla, and lemon zest. Increase the speed to medium-high, and beat for about 3 minutes, or until the frosting is light and fluffy.
• 10. To assemble the cake, place 1 cake layer on a serving plate. Pile the lemon filling onto the center using a small offset metal spatula, and spread it into an even layer, leaving a 1-inch border around the edge of the cake layer. Top with the second cake layer. Frost the top and sides of the cake with the lemon frosting. (If some of the filling oozes out from the middle, just blend it with the frosting around the sides of the cake.) Serve the cake immediately, or refrigerate and bring to room temperature before serving.

Steps:

• For the cake: Preheat the oven to 350 degrees F. Grease three 8-inch-round cake pans with butter and line with parchment paper.
• Place the sugar and oil in the bowl of a stand mixer fitted with the whisk attachment and beat on medium speed until combined. Add the eggs, one by one, until completely incorporated. Add the vanilla extract and buttermilk and continue mixing until combined. 
• Sift the flour, cocoa powder, baking powder, baking soda and salt in a large bowl. Mix together the coffee and warm water. Alternate adding the dry ingredients and the coffee mixture into the bowl of the stand mixer, beginning and ending with the dry ingredients. Mix until you don’t see any lumps and a thin batter has formed.
• Divide the batter evenly among the prepared pans and bake until a toothpick inserted in the middle of each cake comes out clean, 30 to 35 minutes. Transfer the pans to a wire rack and allow to cool for 10 minutes. Remove the cakes from the pans and set on the wire rack to cool completely, about 1 hour. 
• For the dark chocolate mousse: Place the dark chocolate in a large bowl and set aside. Pour 1 cup of the heavy cream into a small saucepan and bring to a boil over medium-high heat. Pour the cream over the chocolate, cover the bowl with a kitchen towel and let sit for 3 minutes.
• Remove the towel and slowly whisk the ganache until it’s smooth and shiny. Set aside to cool to about room temperature.
• Meanwhile, whip the remaining cup of heavy cream to stiff peaks in the bowl of a stand mixer fitted with the whisk attachment, or by hand. Using a rubber spatula, fold one-fourth of the whipped cream into the cooled ganache to lighten the consistency, then fold that mixture into the remaining whipped cream until almost completely combined with just a few streaks. Add the vanilla and salt and gently fold until combined into a light, fluffy mousse. 
• For the chocolate fudge buttercream frosting: Place the sugar, hot fudge, cocoa powder, butter, milk, vanilla extract and salt in the bowl of a stand mixer fitted with the paddle attachment and beat on low speed to combine. When the sugar is incorporated, increase the speed to medium and beat until the buttercream is smooth and satiny, 8 to 10 minutes. 
• For the chocolate royal icing: Place the confectioners’ sugar, cocoa powder, meringue powder and water in the bowl of a stand mixer fitted with the whisk attachment and whip on low speed to combine. Increase the speed to medium-high and whip until the icing holds stiff peaks, 5 to 8 minutes. If it seems too soft, add more confectioners’ sugar in 1 tablespoon increments. If it is too stiff, add a bit more water, drop by drop. Transfer to a piping bag fitted with a medium star tip. 
• For the white chocolate ganache: Place the white chocolate in a medium bowl and set aside. Pour the cream into a small saucepan and bring to a boil over medium-high heat. Pour the cream over the chocolate, cover the bowl with a kitchen towel and let sit for 3 minutes.
• Remove the towel and slowly whisk the ganache until it’s smooth and shiny. Set aside to cool to about room temperature, then transfer to a piping bag fitted with a medium star tip. 
• To assemble, level the tops of the cakes with a serrated knife or cake leveler. Spread half of the mousse over the top of one cake layer. Stack the second layer and repeat. Add the third cake layer and frost the top and sides with a thin coat of the buttercream. Refrigerate until the frosting is firm, 20 to 30 minutes. 
• When the cake is ready, frost the top and sides with a thicker layer of the buttercream and refrigerate again until very firm, about 1 hour. 
• When the cake is almost ready, lightly dust your work area with cornstarch and roll the fondant into a circle about 20-inches wide and 1/8-inch thick. Drape the rolled fondant over the cake and, using a fondant smoother or your hands, lightly press and smooth it onto the cake, working your way from the top down the sides. Pop any air bubbles with a cake tester or toothpick and continue to smooth the surface.
• Trim any excess fondant from the base of the cake with a pizza cutter. Using a pastry brush, lightly brush the bottom half of the cake with the piping gel, then cover it with chocolate sprinkles. 
• Pipe a scalloped border around the edge with the chocolate royal icing. Pipe little rosettes of the white chocolate ganache around the cake and press 1 hazelnut truffle onto each. Continue to pipe and decorate with the royal icing, white chocolate ganache and hazelnut truffles to your liking.
