Hazelnut Praline Buttercream Frosting Recipes

Steps:

• Preheat the oven to 350 degrees with rack in center. Spread nuts on a rimmed baking sheet, and toast them in the oven until they are fragrant, about 8 minutes. Transfer nuts to a clean kitchen towel, and rub nuts in towel vigorously between your hands to remove the brown skins. Lightly brush an 8-by-12-inch rimmed baking pan with the oil. Spread the peeled nuts in the pan.
• In a medium saucepan, combine sugar and lemon juice. Cook over medium heat, brushing down sides of pan with a damp pastry brush to remove any sugar crystals that may form, until mixture is amber, about 9 minutes; do not stir. (Pan may be swirled gently about halfway through to incorporate any uncooked sugar.) Pour directly over nuts to create a thin layer. Set aside to cool, at least 30 minutes.
• Place half the praline in the bowl of a food processor; process until the praline is very fine with no sharp pieces. Cut the remaining praline into small pieces for decoration.

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:

• To make the cake, grease 2 (9 by 2-inch) round cake pans with shortening and line bottoms with parchment rounds. Grease parchment and dust each pan with 1 tablespoon flour, shaking out excess. Set pans aside.
• Preheat oven to 350 degrees F.
• In a medium bowl whisk together the eggs, liqueur, and hazelnut extract until blended and set aside.
• In a large bowl of an electric stand mixer, gently combine on low speed 3 1/3 cups flour, sugar, baking powder, baking soda, salt and hazelnuts until blended. Add the butter and sour cream and beat on low speed until dry ingredients are moistened.
• Increase speed to medium and beat for 2 1/2 minutes, scraping the sides of the bowl occasionally. In 3 separate additions, add the egg mixture to the batter, beating for 30 seconds after each addition. Divide batter evenly into the prepared pans and bake on the center rack for 40 to 45 minutes or until a cake tester inserted into the center of each cake comes out clean. Cool cakes in pans for 10 minutes. Remove from pans, discard parchment and cool cakes completely on wire racks, 1 to 2 hours.
• To make the hazelnut filling, in a medium saucepan melt the butter over medium heat.
• Sprinkle with flour and whisk until smooth. Reduce heat to medium-low, add the sugar and cream and cook, whisking constantly, for 7 to 10 minutes or until mixture is thickened. Stir in the hazelnuts, salt, liqueur, hazelnut extract, and chocolate and cook just until chocolate melts. Set aside in a bowl and cool completely.
• To make the chocolate buttercream frosting, melt chocolate in the top of a double boiler over medium heat until smooth. Set aside, off the heat, and cool completely. In a large bowl whisk together the sugar and egg whites until blended. Place the bowl over a saucepan of simmering water and whisk until mixture reaches 140 degrees F.
• Remove mixture to a large bowl of a stand mixture with a whisk attachment and beat on low speed for 1 minute to cool slightly. Increase speed to high and beat for 4 minutes or until mixture is cool to the touch and doubled in volume. Reduce speed to low and add the softened butter 1 tablespoon at a time, beating well after each addition, until all of the butter has been added. Continue to beat until mixture looks smooth. Fold in the melted chocolate and the hazelnut extract and beat until fluffy.
• To assemble the cake, split each cake layer horizontally in half to make 4 separate layers. Spread equal amounts of the hazelnut filling between each layer and frost top and sides of cake with the buttercream. To garnish, press chopped hazelnuts onto the sides of the cake. Using a pastry bag fitted with a star tip, pipe rosettes around the top rim using remaining frosting. Place whole hazelnuts and chocolate curls on the top of the cake.
• Tip: To make this cake an easier undertaking, take the time to search out hazelnuts that have already been peeled. If peeled nuts are unavailable, working in batches, boil nuts in 2 cups water along with 2 tablespoons baking soda for 1 to 2 minutes.
• Run nuts under water and slip off skins. Dry the nuts well and toast on a baking sheet in a 350 degree F oven for 20 minutes, stirring occasionally. Cool and finely chop and proceed with recipe. If you purchase the nuts already peeled, toast in a 350 degree F oven for only 15 minutes.

Steps:

• In a stand mixer afixed with the paddle attachment, beat together the butter and powdered sugar on low until well-blended. Add the Nutella and increase the speed to medium. Beat for two minutes.
• Add the vanilla extract and salt and whip for an additional 30 seconds.
• Add the whipping cream and beat for about one minute, until the frosting lightens slightly in both color and texture.

Steps:

• Coat a rimmed baking sheet with cooking spray. Heat sugar, corn syrup, water, and a pinch of salt in a small saucepan over medium-high heat, stirring constantly until sugar dissolves. Continue to cook, without stirring, until deep amber. Remove from heat, stir in nuts, and spread evenly on baking sheet. Let cool completely on sheet on a wire rack.
• Break praline into medium pieces, and transfer to a resealable plastic bag. Using a rolling pin, crush into pea-size pieces.

Steps:

• Lightly oil a baking sheet.
• In a dry heavy saucepan cook sugar over moderate heat, stirring with a fork, until melted and cook, without stirring, swirling pan, just until a golden caramel. Add hazelnuts, stirring until coated well. Immediately pour mixture onto baking sheet and cool completely, about 30 minutes. Remove praline from baking sheet and break into pieces.
• Praline may be eaten as candy or ground in a food processor and used as a dessert topping.

Steps:

• Heat the oven to 200 degrees Celsius (nonfan)/375 degrees Fahrenheit. Line the bottom of 2 (20-centimeter/8-inch) cake pans (tins) with a removable base with parchment paper and grease the sides. Alternatively, grease the bottoms and sides of 2 (20-centimeter/8-inch) regular cake pans, line with parchment, and grease the parchment.
• In a large bowl, whisk together cocoa, flour, baking powder, baking soda, salt and sugars. In a separate bowl, add the oil, eggs and kefir, and whisk just to combine. Add to the dry mixture and use a spatula to gently fold through. Add the 3/4 cup plus 3 tablespoons/220 grams hot coffee and mix gently to combine. It'll look very runny at first, but will soon come together into a glossy, pourable batter.
• Divide the batter evenly between the two cake pans, about 21 ounces/600 grams per pan. Bake for 30 minutes or until a skewer inserted into the middle comes out clean. Set aside to cool for about 30 minutes, then slide a butter knife along the sides to help release the cake. Brush the tops lightly with the remaining 1 tablespoon/14 grams extra coffee (discard any extra).
• Invert one cake onto a board, remove the parchment, then invert it again onto a cake stand or the platter you intend to serve it on (domed side up now). Invert the other cake onto a board (don't remove the paper). Invert it again, onto a plate, so that it's paper side down. (This will help prevent it from sticking.) Set both cakes aside to cool completely.
• Make the praline: With the oven still at 200 degrees Celsius/375 degrees Fahrenheit, spread the hazelnuts onto a parchment-lined medium baking sheet (tray) and bake for 12 to 15 minutes, or until deeply golden, shaking the pan halfway through baking. Set aside, keeping the tray and parchment paper. You'll use them again later.
• Place a large saucepan over a medium-high heat and, once quite hot, sprinkle in a third of the caster sugar to cover the base. It should immediately start to melt at the sides but not brown too quickly. Swirl the sugar in the pan a little, then add another third of the sugar, allowing it to melt a little before adding the remaining third. Turn the heat down to medium and cook until the sugar is an amber caramel, stirring with a spatula just a couple times (but not much more). Add the hazelnuts and 1/4 teaspoon salt, stirring to coat, then quickly transfer the mixture to your parchment-lined tray and leave to cool completely.
• Once cool, roughly break apart the praline and add it to a food processor. Pulse a few times until you have very coarse crumbs, then measure out about 1/2 cup/75 grams of the mixture and transfer to a bowl. Blitz the remaining mixture in the food processor for about 5 minutes or until it turns into the consistency of a smooth nut butter, stopping to scrape the inside of the bowl as necessary. Transfer this to a separate bowl.
• Make the mascarpone cream: Add all the ingredients to a stand mixer and beat on medium-high speed for 1 1/2 to 2 minutes, or until you have medium peaks. Refrigerate if not assembling right away (you want it nice and cold).
• When ready to assemble, top the cake on your cake stand with half the cream mixture. Spoon over about 2 tablespoons of the smooth praline and gently swirl it through the cream with your spatula. Top with another 2 tablespoons of the praline, this time without swirling. Sprinkle with half the praline crumble. Carefully invert the other cake on top now, removing the paper. Top with the remaining cream and repeat the same process with the smooth praline and praline crumble. Serve right away, or refrigerate overnight to firm up the cream before serving. (The cake will keep refrigerated for up to 3 days.)

Steps:

• 1. Beat softened butter in a bowl with a hand-held mixer.
• 2. Add powdered sugar - use low speed when incorporating it into the butter, then whip until pale yellow.
• 3. Add the vanilla and the hazelnut praline paste. Beat together until a uniform color.
