Chocolate Hazelnut Coffee Cake Recipes

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:

• Combine both chocolates and melt them over a double boiler. Whisk the yolks and 1/2 of the sugar in a mixer equipped with a whisk, set aside at room temperature. In a separate bowl, whisk the whipping cream to the soft peak stage and set aside, refrigerated. Combine the 3 egg whites with the remaining sugar and whip to a soft peak stage. Pour the melted chocolate into the yolk and sugar mixture and whip at high speed until the mixture begins to pale and increase in volume. Fold in the whipped egg whites and then the whipped cream until smooth and homogenous. Pour into individual 3-inch diameter plastic round bottom (about 1/2 cup capacity) molds and freeze.
• Combine and melt the Gandujia and the hazelnut paste over a double boiler until smooth. Set aside at room temperature. Add the royaltine chips and the peanut oil and fold into the chocolate mixture until smooth. While the mixture is still warm, spread it on a sheetpan in a 1/2-inch layer, evening the surface with the aid of an offset spatula. Refrigerate until solid and then cut into 3-inch circles and refrigerate. These circles will serve as the base for the mousse cakes.
• Combine both of the ingredients over a double boiler and melt until smooth. Allow to cool to a warm stage and fill a container of an electric spray gun with the mixture. The spray gun should be new or has never been used for any purpose other than food.
• To assemble cakes: Remove the crunchy 3-inch discs from the refrigerator and place on plates. Remove mousse molds and unmold on top of the disc. These should be kept frozen until ready to spray with the chocolate mist. Remove mousse cakes from the freezer and spray the chocolate domes liberally to create a velour type finish, while still frozen. Refrigerate until set. Serve the mousse cakes with chocolate sauce and chocolate decorations of your choice.

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:

• Combine the flour, brown sugar, cornflakes, hazelnuts, cinnamon and salt in a small bowl and mix to combine. Add the butter and mix thoroughly with your fingers or a fork until all of the butter has been evenly distributed and incorporated into the flour. Form into small to medium clumps with your fingers.
• Preheat the oven to 350 degrees F. Butter an 8-inch square cake pan.
• Whisk together the flour, baking powder, baking soda and salt in a small bowl.
• Beat the butter and granulated sugar together in a large bowl with an electric mixer on medium-high speed until light and fluffy, about 3 minutes. Add the eggs, 1 at a time, beating well after each addition. Beat in the vanilla. Reduce the speed to low and add the flour mixture in 3 batches, alternating with the sour cream, beginning and ending with the flour, beating until just incorporated.
• Spoon half of the cake batter (it will be very thick) into the prepared pan and smooth with an offset spatula. Dollop the chocolate-hazelnut spread on top and carefully smooth with the spatula. Spoon the remaining cake batter on top and smooth the top. Sprinkle on the crumb topping.
• Bake until the cake and topping are golden brown and a toothpick inserted into the center of the cake comes out clean, about 1 hour. Let cool in the pan 20 minutes, then invert onto a plate and re-invert onto a rack to cool completely. When the cake is cool, dust with confectioners? sugar.
