Hazelnut Cake With Praline And Milk Chocolate Buttercream Frosting Food

HAZELNUT CAKE WITH PRALINE AND MILK CHOCOLATE BUTTERCREAM FROSTING

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.

HAZELNUT PRALINE CHOCOLATE CAKE

Steps:

• Preheat oven to 350 degrees F
• Whisk together sugar, flour, cocoa, baking soda, baking powder and salt in large bowl
• Add eggs, buttermilk, coffee, oil and vanilla; mix to fully incorporate
• Divide batter evenly into 3 - 10" round cake pans
• Bake 20-25 minutes or until toothpick inserted in the center comes out clean
• Preheat oven to 150 degrees C. Roast hazelnuts for about 8-10 mins, then place the hazelnuts between 2 towels and rub the hazelnuts to get the skin off
• In a saucepan, caramelize the sugar one third at a time. Place 1/3 cup of sugar into pan at medium heat, stir and let melt until it reaches a caramel colour. Add in the remainder slowly, making sure to stir continuously
• Once all sugar is caramelized, throw in the hazelnuts and coat them in the caramelized sugar
• Immediately transfer to oil-sprayed cookie sheet. Let the praline cool until hardened
• Break up praline into pieces, process in food processor until it reaches a super fine consistency
• Using a microwave, melt the milk chocolate in 30s intervals, stir in between intervals until just melted and smooth
• Stir the finely processed praline into the chocolate. The mixture should be grainy, don't worry!
• Bring 300mL of heavy cream to a simmer, then slowly pour it into the chocolate praline mixture and stir until evenly combined
• Pour in the remaining cold 700mL heavy cream, stir until combined. You now have your hazelnut praline mousse
• Place the mousse in the fridge for at least 3 hours until completely cold. Place the beaters of your stand mixer/hand mixer into the fridge as well. You want to make sure everything is really cold, but NOT frozen, in order to be able to whip up the cream.
• When it is cold, whip the mixture on medium speed until medium peak forms. Be careful not to overwhip to avoid curdling and breaking the cream.
• In the microwave or on the stovetop, heat up the heavy cream until simmering
• Place chopped chocolate in a bowl, pour the hot cream over it and stir until completely melted and combined
• Set aside on counter to cool until the ganache is still pourable but not warm anymore
• On a cake board or cake stand, place 1 layer of chocolate cake down
• Add a layer of hazelnut praline mousse
• Repeat until the last layer of cake is on top
• Frost the entire cake in the hazelnut praline mousse
• Pour the cooled ganache on top and allow to drip down the edges

CHOCOLATE HAZELNUT CAKE WITH PRALINE CHOCOLATE CRUNCH

Steps:

• For praline chocolate crunch:
• Line 2 rimmed baking sheets with parchment paper. Stir sugar and 1/3 cup water in a small saucepan over medium-low heat until sugar dissolves. Increase heat and cook without stirring, occasionally swirling pan and brushing down sides with a wet pastry brush, until amber in color, 7-8 minutes. Stir in hazelnuts, then pour onto 1 prepared sheet, separating nuts. Let cool.
• Transfer candied nuts to a food processor. Add hazelnut oil and purée until smooth to make praline paste.
• Combine both chocolates and 3 tablespoons praline paste in a medium metal bowl (reserve remaining praline paste for praline mousse layer). Set bowl over a saucepan of simmering water and stir until chocolate is melted and mixture is smooth. Remove from heat and stir in salt, then cereal. Spread out in a thin layer (about 1/8") on second prepared baking sheet. Chill until set, about 30 minutes.DO AHEAD: Can be made 1 day ahead. Cover and keep chilled. Cover and chill remaining praline paste.
• For cake:
• Preheat oven to 375°F. Line a 17x11x1" sheet pan with parchment paper; butter paper. Sift flour and cocoa powder into a medium bowl and set aside. Separate 4 eggs, placing yolks in a large bowl and whites in a medium bowl. Using an electric mixer, beat yolks with 1/2 cup sugar on medium speed until thick and light yellow, about 3 minutes. Beat in 4 whole eggs, one at a time, blending well between additions.
• Using clean, dry beaters, beat egg whites with remaining 1/2 cup sugar and corn syrup until slightly thickened and frothy, about 2 minutes. Add egg-white mixture to egg-yolk mixture and beat to blend. Add flour-cocoa powder mixture; fold just to blend. Spread out evenly on prepared baking sheet.
• Bake until a tester inserted into center of cake comes out clean, about 15 minutes. Let cool completely. Invert cake onto a large cutting board or baking sheet and peel off parchment. Brush cake all over with brandy. DO AHEAD: Can be made 1 day ahead. Store airtight at room temperature.
• For nut ganache:
• Bring cream to a boil in a small saucepan. Purée hot cream, hazelnut butter, and salt in a food processor. Let cool to room temperature. With machine running, add butter, 1 tablespoon at a time, puréeing until smooth between additions. DO AHEAD: Can be made 1 day ahead. Cover and chill. Return to room temperature before using.
• Praline Mousse:
• Combine chocolate, praline paste, and butter in a medium bowl. Bring 3/4 cup cream to a boil in a small saucepan; pour over chocolate mixture. Let stand for 1 minute, then stir until melted and smooth. Beat remaining 1 cup chilled cream until soft peaks form. Fold whipped cream into chocolate mixture. DO AHEAD: Can be made 1 day ahead. Cover and chill.
• Assembly:
• Spread nut ganache over cake and chill in freezer until set, about 15 minutes. Spread mousse over ganache and chill in freezer until set, about 15 minutes. Cut cake crosswise into thirds; stack layers on top of each other. Trim edges, then spread Chocolate Glaze epi:recipelinkover top and sides of cake. Freeze until set, about 1 hour. Place in refrigerator and chill overnight. DO AHEAD: Can be made 2 days ahead. Tent with foil and keep chilled.
• Let cake stand at room temperature for 30 minutes before serving. Break up praline chocolate crunch into large shards and arrange on top of cake. Garnish with roasted hazelnuts.

TRIPLE HAZELNUT CAKE WITH CHOCOLATE BUTTERCREAM FROSTING

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.

HAZELNUT CAKE WITH CHOCOLATE PRALINE BUTTERCREAM

Steps:

• Position rack in the lower 3rd of the oven and preheat to 350 degrees. Grease and flour a 10" X 2" inch round cake pan.
• Using a food processor, process nuts, cake flour, and cornstarch for about 30 seconds. Then, pulse the mixture about 10 times to get a fine, powdery mixture. You'll know the nuts are ready when they begin to gather together around the sides of the bowl. While you want to make sure there aren't any large pieces, don't over-process. Set aside.
• Put the yolks in the bowl of an electric mixer, with the whisk attachment, and beat until thick and light in color, about 3-4 minutes on med-high speed. Slowly, add ¾ cup of sugar. It is best to do so by adding a tablespoon at a time, taking about 3 minutes for this step. When finished, the mixture should be ribbony. Blend in the vanilla and grated lemon rind. Remove and set aside.
• Place egg whites in a large, clean bowl of the electric mixer with the whisk attachment and beat on medium speed, until soft peaks. Increase to med-high speed and slowly add the remaining ¼ cup of sugar, over 15-20 seconds or so. Continue to beat for another ½ minute.
• Add the yolk mixture to the whites and whisk for 1 minute.
• Pour the warm butter in a liquid measure cup (or a spouted container). * It must be a deep bottom bowl and work must be fast.* Put the nut meal in a mesh strainer (or use your hand - working quickly) and sprinkle it in about 2 tablespoons at a time - folding it carefully for about 40 folds. Be sure to exclude any large chunks/pieces of nuts. Again, work quickly and carefully as to not deflate the mixture. When all but about 2 Tbsp. of nut meal remain, quickly and steadily pour the warm butter over the batter. Then, with the remaining nut meal, fold the batter to incorporate, about 13 or so folds.
• With a rubber spatula, transfer the batter into the prepared pan, smoothing the surface with the spatula or back of a spoon. If collected butter remains at the bottom of the bowl, do not add it to the batter! It will impede the cake rising while baking.
• Tap the pan on the counter to remove air bubbles and bake in the preheated oven for 30-35 minutes. You'll know the cake is done when it is springy to the touch and it separates itself from the side of the pan. Remove from oven and allow to stand for 5 minutes. Invert onto a cake rack sprayed with nonstick coating, removing the pan. Cool the cake completely.
• If not using the cake right away, wrap thoroughly in plastic wrap, then in a plastic bag, then in the refrigerator for up to 3 days. If freezing, wrap in foil, then the bag and use within 2-3 months.
• Put the sugar in a heavy 10-inch skillet. Heat on low flame for about 10-20 min until the sugar melts around the edges. Do not stir the sugar. Swirl the pan if necessary to prevent the melted sugar from burning. Brush the sides of the pan with water to remove sugar crystals. If the sugar in the center does not melt, stir briefly. When the sugar is completely melted and caramel in color, remove from heat. Stir in the nuts with a wooden spoon and separate the clusters. Return to low heat and stir to coat the nuts on all sides. Cook until the mixture starts to bubble. **Remember - extremely hot mixture.** Then onto the parchment lined sheet and spread as evenly as possible. As it cools, it will harden into brittle. Break the candied nuts into pieces and place them in the food processor. Pulse into a medium-fine crunch or process until the brittle turns into a powder. To make paste, process for several minutes. Store in an airtight container and store in a cook dry place. Do not refrigerate.
• In a small, yet heavy saucepan, bring the water and sugar to a boil and simmer for 5 minutes. Remove from heat, add the liqueur. Cool slightly before using on the cake. *Can be made in advance.
• Blend ½ cup buttercream into the paste, then add to the remaining buttercream. Whip briefly on med-low speed to combine. Blend in rum.
• Place the egg whites in a lg/ bowl of a elevtric mixer and beat with the whisk attachment until the whites are foamy and they begin to thicken (just before the soft peak stage). Set the bowl over a saucepan filled with about 2 inches of simmering water, making sure the bowl is not touching the water. Then, whisk in the sugar by adding 1-2 tablespoon of sugar at a time over a minutes time. Continue beating 2-3 minutes or until the whites are warm (about 120 degrees) and the sugar is dissolved. The mixture should look thick and like whipped marshmallows.Remove from pan and with either the paddle or whisk attachment, beat the egg whites and sugar on med-high until its a thick, cool meringue - about 5-7 minutes. *Do not overbeat*. Set aside.
• Place the butter in a separate clean mixing bowl and, using the paddle attachment, cream the butter at medium speed for 40-60 seconds, or until smooth and creamy. *Do not overbeat or the butter will become toooooo soft.*
• On med-low speed, blend the meringue into the butter, about 1-2 Tbsp. at a time, over 1 minute. Add the liqueur and vanilla and mix for 30-45 seconds longer, until thick and creamy.
• Refrigerate 10-15 minutes before using.
• Wait! My buttercream won't come together! Reheat the buttercream briefly over simmering water for about 5 seconds, stirring with a wooden spoon. Be careful and do not overbeat. The mixture will look broken with some liquid at the bottom of the bowl. Return the bowl to the mixer and whip on medium speed just until the cream comes back together.
• Wait! My buttercream is too soft! Chill the buttercream in the refrigerator for about 10 minutes and rewhip. If that doesn't work, cream an additional 2-4 Tbsp. of butter in a small bowl- making sure the butter is not as soft as the original amount, so make sure is cool and smooth. On low speed, quickly add the creamed butter to the buttercream, 1 Tbsp. at a time.
• Refrigerate in an airtight container for up to 5 days, or can be frozen for up to 6 months. If freezing, store in 2 16-oz. plastic containers and thaw in the refrigerator overnight or at room temperature for several hours.
• In a small, yet heavy saucepan, bring the water and preserves to a slow boil and simmer for 2-3 minutes. If the mixture begins to stick to the bottom of the saucepan, add water as needed.
• Remove from heat and, using a strainer, press the mixture through the mesh and discard any remnants. With a pastry brush, apply the glaze onto the cake while the cake is still warm. If the glaze is too thick, thin to a preferred consistency with drops of water.
• Blend vanilla and liqueur/rum together and set aside.
• Break the chocolate into 1-inch pieces and place in the basket of a food processor and pulse until finely chopped. Transfer into a medium sized bowl and set aside.
• Heat the cream and corn syrup in a saucepan, on low, until it reached a gentle boil. Once to the gently boil, immediately and carefully pour over the chocolate. Leave it alone for one minute, then slowly stir and mix the chocolate and cream together until the chocolate is melted and incorporated into the cream. Carefully blend in vanilla mixture. If the surface seems oily, add ½ - 1 tsp hot water. The glaze will thicken, but should still be pourable. If it doesn't thicken, refrigerate for about 5 minutes, but make sure it doesn't get too cold!
• Cut a cardboard disk slightly smaller than the cake. Divide the cake into 3 layers and place the first layer top-side down on the disk. Using a pastry brush, moisten the layer with 3-4 Tbsp. of warm sugar syrup. Measure out 1 cup of praline buttercream and set aside.
• Spread the bottom layer with a ¼-inch thickness of the remaining buttercream. Cover with ½ of the whipped cream, leaving ¼-inch border around the edge of the cake. Place the middle layer over the first, brush with sugar syrup, spreading with buttercream. Cover with the remaining whipped cream.
• Moisten the cut side of the third layer with additional sugar syrup and place cut side down on the cake. Gently, press the sides of the cake to align the layers. Refrigerate to chill for at least 30 minutes.
• Lift the cake by sliding your palm under the cardboard. Holding a serrated or very sharp night with an 8-ich blade held parallel to the sides of the cake, trim the sides so that they are perfectly straight. Cut a slight bevel at the top to help the glaze drip over the edge. Brush the top and sides of the cake with warm apricot glaze, sealing the cut areas completely. Chill while you prepare the ganache.
• Place a rack over a large shallow pan to catch the ganache drippings. Remove the gateau from the refrigerator and put it the rack. With a metal spatula in hand, and holding the saucepan about 10 inches above the cake, pour the ganache onto the cake's center. Move the spatula over the top of the ganache about 4 times to get a smooth and mirror-like appearance. The ganache should cover the top and run down the sides of the cake. When the ganache has been poured and is coating the cake, lift one side of the rack and bang it once on the counter to help spread the ganache evenly and break any air bubbles. (Work fast before setting starts.) Patch any bare spots on the sides with a smaller spatula, but do not touch the top after the "bang". Let the cake stand at least 15 minutes to set after glazing.
• To garnish the cake, fit a 12 - 14-inch pastry bag with a #114 large leaf tip. Fill the bag with the reserved praline cream. Stating ½ inch from the outer edge of the cake, position the pastry tube at a 90 degree angle with the top almost touching the top of the cake. Apply pressure to the pastry bag, moving it slightly toward the center of the cake. As the buttercream flows on the cake, reverse the movement backward toward the edge of the cake and finish by pulling the bag again to the center. Stop applying pressure and press the bag downward, then quickly pull the tip up to break the flow of frosting. Repeat, making 12 leaves evenly spaced around the surface of the cake.
• Make a second row of leaves on the top of the first row, moving the pastry bag about ¾ inch closer to the center. The leaves should overlap. Make a 3rd row, moving closer and closer to the center. Add a 4th row if you have the room. But, leave a 2-inch space in the center for a chopped filbert garnish. Refrigerate uncovered for 3-4 hours to allow the cake to set. Remove the cake from the refrigerator at least 3 hours before serving.
• Leftover cake can be covered with foil and kept in the refrigerator for up to 5 days.

HAZELNUT PRALINE LAYER CAKE

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.
