Hazelnut Praline Layer Cake Recipes

Steps:

• Place an oven rack in the middle position. Preheat oven to 375 degrees. Spray a 9-by-3-inch round cake pan with vegetable spray. Line a baking sheet with parchment paper or a nonstick silicone baking mat; set aside.
• Make the sponge cake: Grind the hazelnuts in a food processor with 1/4 cup sugar. In a medium bowl, sift together flour, cornstarch, and hazelnut mixture; set aside.
• In the bowl of an electric mixer fitted with the whisk attachment, beat the whole eggs, the yolks, remaining 1/2 cup sugar, salt, and almond extract on high speed until thick and pale yellow in color, and mixture holds a thick ribbon when whisk is lifted from bowl, 7 to 8 minutes. Remove bowl from mixer; gently and quickly fold in flour mixture. Gradually drizzle in oil, while folding.
• Pour batter into prepared cake pan. Set on prepared baking sheet, and bake until a tester comes out clean when inserted into the center of the cake, about 25 to 30 minutes. Remove from oven and turn cake out immediately onto a wire rack. Let cool for at least 1 hour.
• Make the buttercream: In the heatproof bowl of an electric mixer set over (but not touching) simmering water, whisk egg whites, sugar, and salt until warm to the touch, 1 to 2 minutes. Transfer bowl to mixer fitted with whisk attachment and beat until stiff peaks form. With the mixer running, gradually beat in butter, piece by piece. When all the butter has been added, mixture will break but it will become smooth as you continue to beat. Beat in vanilla. Divide buttercream in half, returning one half to the mixer bowl to make the chocolate flavor and setting aside the remaining half for the praline buttercream.
• Melt the chocolate in a heatproof bowl set over (but not touching) simmering water. Slowly beat into buttercream in mixer. Add cocoa mixture and beat until buttercream is cooled; set aside.
• Using a small offset spatula, spread praline paste onto a clean work surface. Smooth paste with a spatula, working out any lumps. Add 1/2 cup reserved buttercream to praline paste and fold it into buttercream. Once the paste and buttercream are fully combined and there are no lumps, fold praline mixture into remaining reserved buttercream.
• Using a serrated knife, trim top of cake to make level. Cut cake horizontally into even thirds. Place four strips of parchment paper around perimeter of a serving plate or lazy Susan. Place the first layer on the cake plate and top with a 1/3- to 1/2-inch layer of praline buttercream. Place second layer on top; top with remaining praline buttercream. Top with remaining layer.
• Spread a thin layer of the chocolate buttercream over the tops and sides of the cake to cover, creating a "crumb" layer. Transfer to refrigerator for 15 minutes to set. Spread tops and sides of cake with remaining chocolate buttercream; serve.

Steps:

• Cake.
• Set a rack in the middle of the oven, and preheat to 375 degrees. Lightly coat two 9-inch cake pans with nonstick vegetable spray. Line the bottom of each pan with a circle of baking parchment.
• Sift the flour, baking powder, baking soda, and salt together three times.
• In the bowl of an electric mixer fitted with a paddle, beat the butter and sugar at high speed for 15 seconds, until combined. Add the eggs one at a time, beating until each is incorporated.
• Continue beating on high until light and fluffy, about 6 minutes more.
• With the mixer on its lowest setting, beat in a third of the flour mixture. Beat in half the buttermilk and all the Frangelico, then the hazelnuts and another third of the flour mixture. Beat in the remaining buttermilk and then the remaining flour.
• Spread the batter in the prepared pans and bake about 20 to 25 minutes, until cake is golden brown and the center springs back when lightly pressed and a cake tester comes out clean.
• Set the pans on a rack to cool. Turn out the cakes when cool enough to handle. (If the cakes are refrigerated for 2 hours at this stage, they will be easier to handle and frost.).
• Praline Buttercream.
• Put 1/2 cup water and the sugar in a small saucepan fitted with a candy thermometer. Over high heat, bring the temperature to 240 degrees (soft-ball stage).
• In the meantime, in the completely clean and dry bowl of an electric mixer, whisk the egg whites, salt, and cream of tartar until creamy, foamy, and barely able to hold very soft peaks. With the mixer running on slow, carefully drizzle in the hot syrup. Continue to whisk on high speed until mixture is fluffy, firm, and cooled to room temperature; gradually beat in the butter and then the praline paste.
• When the cakes are cold, trim the tops with a large serrated knife. Split each cake into two layers.
• Spread a 1/4-inch layer of the buttercream between each layer. Frost the outside of the cake with the remaining buttercream, and then coat the sides of the cake with the chopped hazelnuts.
• Optional.
• Decorate top of cake with whole hazelnuts, blackberries, or raspberries to form a row around the edge.

Steps:

• For crust:
• Position rack in center of oven; preheat to 350°F. Butter 9-inch-diameter springform pan with 2 3/4-inch-high sides. Mix flour, butter and brown sugar in processor until moist clumps form. Press mixture onto bottom of prepared pan. Bake until crust is golden, about 25 minutes. Cool. Wrap outside of pan with double layer of heavy-duty foil.
• For filling:
• Reserve 1/2 cup praline for garnish. Grind remaining praline to powder in processor. Beat cream cheese and su gar in large bowl until smooth. Beat in flour, then cream and vanilla. Beat in eggs 1 at a time. Fold in praline powder.
• Transfer filling to crust. Place springform pan in roasting pan. Pour enough hot water into roasting pan to come halfway up sides of springform pan. Bake until center is just set, about 1 hour 20 minutes.
• Transfer cake to rack. Run small sharp knife around sides of cake to loosen. Cool completely. Remove foil from pan sides. Chill cake overnight. (Can be prepared 3 days ahead. Cover and keep refrigerated.)
• Release pan sides. Transfer cake to platter. Mound reserved coarsely crushed praline atop center of cake and serve.
