The Best Chocolate Hazelnut Cake Recipes

Steps:

• Preheat the oven to 375 degrees F. Prepare the springform pan by coating it in a thin layer with 2 tablespoons of the softened butter. Add the cocoa powder to the pan and tap the sides to coat the bottom and sides evenly. Discard any excess cocoa powder. Put the hazelnuts on a baking sheet and toast in the oven on the center rack until just fragrant, 8 to 10 minutes. Transfer immediately to a kitchen towel to stop them from cooking. Use the towel to rub off the skins. Set aside to cool. Lower the oven to 350 degrees F.
• Fill a 1- to 2-quart pot with about 1 inch of water and bring it to a bare simmer over medium heat. Place the dark chocolate pieces into a heatproof bowl and set it over the pot and simmering water (this is a bain-marie). The water should not touch the bottom of the bowl. Let the chocolate melt, and then stir gently. Remove from the heat when melted.
• Chop the hazelnuts into small pieces using a chef's knife or a food processor. Make sure you don't turn them into powder. Whip the egg whites with an electric mixer with the salt until they are almost at stiff peaks. Try not to over-whip. Mix together the remaining 5 tablespoons butter with the chocolate hazelnut spread in a large bowl with a wooden spoon. Stir in the espresso. Add the yolks and stir briskly to combine. Stir in the chopped hazelnuts and melted chocolate. Add one-fourth of the whipped egg whites to the chocolate hazelnut mixture and stir to lighten the batter. Then gently fold the rest of the egg whites into the batter in 3 additions. Don't over-fold. Pour the batter into the prepared cake pan.
• Bake on the center rack of the oven until the sides of the cake start releasing from edges of the pan, 40 minutes. This cake is almost a hazelnut fudge, so no need to poke with a toothpick to check if the inside is ready or not. The cake will come out of the oven nice and fluffy and souffled, but it will deflate to half the size during its cool-off period. Serve garnished with some powdered sugar and whipped or cream or gelato, if using.

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:

• For the cake: Preheat the oven to 350 degrees F.
• Grease four 6-inch-round, 3-inch-tall cake pans and line the bottoms with parchment.
• Put the hazelnuts in a food processor and grind them until you have small crumbs. Measure out 1/4 cup of the hazelnut crumbs and set them aside for the frosting.
• Pour the remaining hazelnut crumbs into a large bowl and whisk in the flour, granulated sugar, cocoa powder, baking powder, salt and baking soda. In a medium bowl, whisk together the milk, oil, vanilla and eggs. Whisk the wet ingredients into the dry ingredients and then stir in the hot coffee. It will be a very thin batter.
• Pour into the prepared cake pans and bake until a toothpick inserted into the center comes out clean. Begin checking for doneness at 25 minutes. Let the cakes cool in the pans for 10 minutes, then turn them onto a greased cooling rack.
• For the frosting: While the cakes are cooling, use an electric mixer to beat together the powdered sugar, butter, vanilla and salt until smooth. Mix in the heavy cream until smooth. Scoop out a tiny amount of frosting for the mustard-colored dollops, add the mustard yellow food coloring and mix until combined. Transfer the yellow frosting to a piping bag with a small round tip. To the remaining frosting, add the dusty rose pink food coloring and mix until the desired shade of pink. Measure out 1 cup of the pink frosting and transfer it to a small bowl. Fold in the reserved 1/4 cup ground hazelnuts.
• Level your cake layers and spread the top of one of them with the hazelnutty frosting. Place a second layer on top, then frost the top with more of the hazelnutty frosting. Continue with the remaining 2 layers. Frost the top and sides with the remaining pink frosting without nuts.
• For the decorations: Decorate with mustard dollops of frosting around the edge. Add marzipan house cutouts of white houses with green shutters, crushed hazelnuts, green grass sprinkles, orange sun sprinkles or whatever else you'd like!

Steps:

• 1 Preheat oven to 325°F. Spray twelve 3-inch cake molds or one 9-inch springform pan lightly with nonstick cooking spray and set aside.
• 2 Fill the bottom of a double boiler one-third full with water and bring to a simmer over medium-low heat. Place a medium stainless-steel bowl over the water and melt the chocolates together, stirring constantly. Once melted, set aside to cool.
• 3 In the bowl of a food processor, pulse the hazelnuts with the confectioners' sugar and cocoa to form a fine, sand-like mixture.
• 4 In an electric mixer, beat the butter and 3/4 cup of the granulated sugar until very light and fluffy. Beat in the hazelnut paste, scraping down the sides of the bowl with a spatula, then beat in the egg yolks, one at a time. Beat in the espresso, Frangelico, and vanilla extract, followed by the melted chocolate. Fold in the nut mixture.
• 5 In a separate mixing bowl, use the whip attachment to beat the egg whites until foamy. Gradually add the remaining 5 tablespoons of sugar and continue beating until soft peaks form. Using a rubber spatula, gently fold the egg whites into the cake batter. Place the prepared molds on a greased baking sheet and divide the batter evenly among them.
• 6 Bake the cakes just until they puff and crack slightly, about 14 minutes for the cake molds (45 to 50 minutes if using the springform pan). Remove from the oven and cool in the molds on a wire rack. When the cakes are almost completely cool, gently remove the molds, then chill in the refrigerator until firm. The cakes will last for up to 1 week, refrigerated in an airtight container.

Steps:

• Prepare the crepe batter: Whisk together eggs, egg yolks, milk and cream in a medium bowl. In a large bowl, whisk together flour, hazelnut meal, sugar and salt. Make a well in the center of the flour mixture and pour in some of the milk mixture. Gently whisk from the center of the well, making a thick, smooth batter. Then, while whisking, gradually add remaining milk mixture and whisk until smooth. Whisk in vanilla and butter. (Alternatively, combine all the ingredients in a blender and blend on low speed until smooth.) Cover and refrigerate for at least 2 hours and up to 48 hours.
• Prepare the chocolate cream: Place chopped chocolate in a medium bowl and set a fine mesh sieve over the bowl. In a medium saucepan, whisk together sugar, cornstarch, cocoa powder and salt. Whisk in some of the milk to create a thick paste. Gradually add remaining milk while whisking until mixture is smooth and well-combined. Whisk in egg yolks and add butter.
• Cook milk mixture over medium heat, whisking constantly and occasionally scraping the bottom and sides of the pan with a rubber spatula. Once the mixture comes to a boil and becomes very thick, about 5 minutes, whisk it vigorously for 1 to 2 minutes. Press hot cream mixture through the sieve into the bowl with the chocolate. Let it stand for 2 minutes, then mix it until smooth and well-combined. Add brandy or coffee and stir to combine. Use a rubber spatula to stir the mixture until it has cooled to about room temperature and is smooth and silky. Cover with plastic wrap, pressed into the surface of the custard, and chill until ready to use.
• Cook the crepes: Melt a little bit of butter in an 8-inch nonstick skillet over medium heat and let the pan get hot. Remove the pan from the heat and immediately add a scant 1/4 cup (about 3 tablespoons) crepe batter to one side of the pan. (You don't want to use too much batter or you'll have thick crepes.) Quickly tilt and swirl the pan to spread the batter to an even thickness across the bottom of the pan and about 1 inch up the sides.
• Return the pan to the heat and cook crepe until very lightly golden and set on one side, about 45 seconds. Tuck a small offset spatula under the edge of the crepe, grab onto it with your fingers, and quickly flip it over. Cook until light golden brown on the other side, 30 seconds to 1 minute. Slip crepe onto a rack to cool. Once crepes are cool, transfer them to a baking sheet and cover with a light towel to keep them from drying out. Continue with remaining batter, occasionally wiping out the skillet with a paper towel and very lightly buttering the skillet every few crepes as needed. You should have 20 to 24. (You need 20 for the cake.)
• To assemble, stir the cream until smooth. Lay 1 crepe on a cake plate. Using an offset spatula, cover with a thin layer of chocolate cream (2 to 3 tablespoons), leaving a 1/4-inch border. Cover with a crepe and repeat to make a stack of 20, with the best-looking crepe on top. Cover with plastic wrap and chill for at least 2 hours.
• To serve, top with whipped cream, nuts and dust with cocoa.
