Hazelnut Cake With Chocolate Praline Buttercream 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.

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.

CHOCOLATE HAZELNUT PRALINE CAKE

Steps:

• Place the hazelnuts in a dry skillet on the stove over medium-high heat. Toast for about 5-7 minutes, until they start to turn golden brown. Set aside to cool.
• Line a baking sheet with a silicone mat or a piece of parchment paper.
• In a medium saucepan, combine the sugar and 1 1/2 tablespoons water. Cook over medium-high heat swirling the pan occasionally to evenly distrute heat. Cook until the sugar has melted and turns a deep amber color. Do not stir.
• Stir in the hazelnuts. Pour the caramel onto the lined baking sheet in an even, thin layer.
• Allow the praline to cool and harden completely. Cut into smaller shards with a sharp knife.
• Reserve 3 tablespoons of praline for sprinkling. Place the remaining praline into a small food processor.
• Process the praline mixture until it forms a fine powder. After 5 -7 minutes, it will start forming a paste. If it doesn't, after blending a while, add 1 teaspoon of canola oil to help it get it going.
• Blend the paste until smooth.
• Pour the finished hazelnut praline paste into an air-tight container to store and set aside while preparing the ganache.
• Place the chopped chocolate into a medium size bowl. Set aside.
• Heat the heavy cream and salt in a small sauce pan over medium-low heat on the stove until the mixture begins to simmer.
• Pour the hot cream over the chocolate. Let the mixture sit for a minute to allow the chocolate to melt. Gently whisk the chocolate and cream until smooth.
• Stir in the praline paste.
• Let the ganache cool to room temperature. It will thicken as it cools, to a peanut butter like consistency.
• Preheat the oven to 350F. Butter the bottoms and sides of 2 - 8" x 2" round cake pans. Line the bottoms with parchment. Create a parchment collar to go around the sides of the pans.
• In a medium bowl, combine the flour, espresso powder, cocoa powder, baking powder and salt. Whisk to combine
• In a measuring cup, combine the buttermilk and vanilla. Whisk to combine.
• Place the softened butter and the brown sugar into the bowl of a stand mixer. Using the paddle attachment, cream the butter and the brown sugar on medium speed until it is very light in color and super fluffy, about 6-8 minutes.
• Add the eggs one at a time, mixing just until combined. Scrape the bottom and sides of bowl with spatula after each addition.
• Add one third of the flour mixture to the bowl and mix on low until just combined. Pour half of the buttermilk mixture into the bowl and mix on low until just combined.
• Remove the bowl from the mixer. Scrape the bowl to make sure the ingredients are incorporated. The mixture might look curdled at this point, but it will come back together.
• Add an additional one third of the flour mixture and mix until just combined. Add the remaining buttermilk mixture and mix just until combined.
• Add the remaining flour mixture and mix until just combined. Remove the bowl from the mixer. Scrape the sides and bottom of the bowl to make sure there are not any pockets of butter or flour remaining.
• Add the mayo. Scrape the sides and bottom of the bowl to make sure the ingredients are incorporated.
• Combine the baking soda and vinegar in a small bowl. Pour the mixture into the cake batter and mix on low for an additional 10 seconds.
• Remove the bowl from the mixer. Portion the batter evenly into the prepared pans.
• Bake the cakes on the center rack of the oven for 40-50 minutes, or until a toothpick inserted in the center comes out with a few crumbs. You will want to start watching for the cakes to be done, when the tops dome and start to crack a bit.
• Remove the baked cakes from the oven. If they have domed at all, use a tea towel to gently press down the domes. Let the cakes cool in the pans for 10 minutes.
• Run a butter knife around the edge of the pans, remove the parchment collar and turn the cakes out onto a wire rack. Cool to room temperature.
• Wrap the cakes tightly with a couple layers of plastic wrap and place in the refrigerator to chill completely before assembling.
• The cakes will keep tightly wrapped in plastic wrap and placed in a zip top bag in the refrigerator for up to three days. The cake layers can also be frozen, wrapped well in plastic wrap and placed in a zip top bag. I personally don't like to freeze longer than a week, but you can freeze these layers for up to three weeks. Defrost the layers in the refrigerator before using.
• In the bowl of a stand mixer fitted with the paddle attachment, beat the egg yolks on high speed until extremely light in color.
• Combine the sugar and 1⁄2 cup (120 ml) water in a small saucepan and heat, stirring occasionally, until the mixture boils. Stop stirring, and continue boiling the mixture until it reaches 238 F (115 C) on a candy thermometer. Remove immediately from the heat.
• Pour a small quantity of syrup over the yolks with the mixer turned off. Beat on high speed for 5 seconds, then stop the mixer and add a larger quantity of syrup. Beat on high speed for another 5 seconds. Add the remaining syrup, and continue beating until the mixture is completely cool. Add the butter a few pieces at a time, and beat until the mixture is completely smooth.
• Add in the cooled espresso and salt and beat until well combined.
• Work with chilled cake layers. Using a long serrated knife torte the layers, cutting them evenly in half. You will have four cake layers total. The tops of the cakes will be the center two layers of your cake.
• Put one of the cake layers, cut side up onto an 8" cake board or directly onto a cake stand.
• Spread a thin, even layer of the ganache on the cake layer with an offset spatula. Sprinkle 1/3 of the praline on top.
• Spread about one cup of the buttercream on top of the ganache using an offset spatula to evenly distribute the buttercream. You're looking for the buttercream to be about 1/4 inch thick.
• Place another cake layer on top, top up, and press down gently so that the layer is adhered to the buttercream. Repeat the previous two steps, applying the ganache and buttercream.
• Place the third layer cake layer, top up, and press down gently so that the layer is adhered to the buttercream.
• Add the final ganache layer. Add the final buttercream layer. Place the final cake layer (the bottom of one of the cakes) bottom side up on the buttercream, pressing gently to adhere.
• Frost the cake with the remaining espresso French buttercream. Decorate. Chill in the refrigerator for 30 minutes before serving. Enjoy!

DEVIL'S FOOD CAKE WITH HAZELNUT PRALINE

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.)

CHOCOLATE HAZELNUT PRALINE TORTE WITH FRANGELICO WHIPPED CREAM

Steps:

• Preheat oven to 350°F. Butter an 8 1/2-inch springform pan (2 inches deep) or other cake pan with same dimensions and line bottom with a round of wax paper. Butter paper and dust pan with flour, knocking out excess flour.
• In a food processor pulse praline until ground fine. Reserve 1/4 cup ground praline and transfer remaining praline to a bowl. In food processor pulse chocolate until finely ground and add to bowl of praline.
• In a bowl with an electric mixer cream together butter, salt, and 1/4 cup sugar until light and fluffy. Beat in yolks, 1 at a time, beating well after each addition, and beat in vanilla. Stir in praline chocolate mixture (mixture will be very thick).
• In another bowl with cleaned beaters beat whites until foamy and add a pinch salt and remaining 1/4 cup sugar in a steam, beating until meringue just holds stiff peaks. Fold one third meringue into yolk mixture to lighten and fold in remaining meringue gently but thoroughly. Pour batter into pan and smooth top.
• Bake tort in middle of oven 45 to 55 minutes, or until it begins to pull away from side of pan. Cool torte in pan on a rack (torte will fall slightly and continue to set as it cooks) and remove from pan. Torte may be made 1 day ahead and chilled, covered. Bring torte to room temperature before serving.
• In a bowl with an electric mixer beat cream until it just holds soft peaks. Stir in Frangelico and half of reserved praline.
• Top torte with whipped cream and sprinkle with remaining reserves praline. Serve torte immediately.
