This flourless chocolate hazelnut cake manages to be both rich and somewhat fudgy while yet maintaining a light texture. It has a delicious nutty flavor thanks to the ground hazelnuts, and it's almost like having Nutella in a cake shape. Making a flourless chocolate cake is very simple. Eggs and crushed nuts provide the cake's primary structure. Cocoa and fine, dark Chocolate are used to enhance the chocolate flavor, as are the other necessary ingredients for a stunning dessert. Finely ground hazelnuts make up a substantial portion of flourless cakes. In this recipe, I used hazelnuts, but you may also use almonds if you like. In this recipe, I use both cocoa and chocolate to ensure that it has a strong chocolate taste. Just use plain white sugar; it's all that's needed. To keep the cake moist, you should use brown sugar instead. Separated eggs: You'll need four eggs for this recipe. To give the cake a lift, the egg whites are beaten. Infusing a chocolate flavor with vanilla essence is a good technique to enhance the flavor. Salt is also used to enhance and balance the chocolate flavor. Baking powder is a simple ingredient that gives a cake a little more lift. The oven should be preheated to 180C fan-forced. Line the bottom and sides of a 9-inch spring form pan with baking paper and then grease the sides. Tip the hazelnuts onto a baking sheet lined with baking paper and spread them out in an equal layer. 
Every 5 minutes or so while in the oven, shake the pan to ensure even toasting. After letting the hazelnuts cool for five minutes, crush them in a food processor to a fine powder. The wet hazelnuts may leak their oil if you combine them for too long, so be careful not to overdo it. It's time to whip up some fluffy icing by combining butter, sugar, vanilla extract, and egg yolks one at a time until they're all well-combined. Finally, add the melted chocolate and stir it all together. 'til Add flour, cocoa, baking powder, and salt to the crushed hazelnuts, cocoa powder, and salt. Slowly pour it into the butter mixture while using a mixer on low speed until well blended. Whisk the egg whites until they form soft peaks in a clean basin. Incorporate a third of the egg whites into the batter. Fold in the remaining two-thirds of the dough in gentle, measured folds until all of the ingredients are integrated. Mixing should be kept to a minimum to save as much air as feasible. Allow to bake for 50–55 minutes, or until the top seems to be crisp and an inserted toothpick has a few wet crumbs on it. Make sure it's absolutely cold before you remove it from the tin. Allow the cake to cool fully before transferring it to a cake plate. Before serving, sprinkle with chocolate powder. 
Flourless hazelnut cake
This cake is flourless and bursting with luscious flavors of hazelnut, chocolate, and a wonderful crunchy topping, yet it's not excessively sugary. In addition to being Vegan, it does not include gluten or grains and does not contain any processed sugar. To get the most flavorful and wholesome hazelnut meal, use a food processor to ground activated whole hazelnuts. If you don't want to make your hazelnut meal, you may use store-bought. You may make the cake in a spring form cake pan that is 20 centimeters in diameter, or you can double the recipe and bake the cake in a tin that is 25 centimeters in diameter. Put the oven on to 320F or 160C. Prepare a cake pan with a diameter of 20 centimeters by greasing it and lining the bottom and sides with baking paper. To begin making the hazelnut cake, place the 3 cups of hazelnuts into a food processor and pulse until they are ground into hazelnut meal. Be careful not to over-process, otherwise, you'll wind up with hazelnut butter instead. Combine the hazelnut meal, baking powder, and salt in a large basin and stir well. Combine the eggs, maple syrup, vanilla extract, and butter in a separate, larger bowl. Combine the two separate ingredients by gently folding them together, taking care not to overmix. Put the batter into the prepared pan for the cake. Bake for thirty to forty minutes, or until the center of the cake is set. If the cake is browning too quickly, cover the top of it with a sheet of baking paper. Please allow the cake to cool completely in the pan. To prepare the chocolate frosting, place all of the icing ingredients in a blender and process until the mixture is silky smooth and velvety. If the frosting seems to be too thin, place it in the refrigerator for ten minutes to thicken it up. 
In a small frypan, melt the coconut oil or butter over low heat to make the crispy hazelnut topping. Prepare a half cup's worth of chopped hazelnuts. When the hazelnuts and maple syrup are aromatic, add them to the pan, and stir everything together for approximately five minutes. Take it off the heat, and let it cool. When the cake is completely cold, spread the frosting on top and then sprinkle the hazelnuts on top of that. You may substitute the hazelnuts with any other kind of nuts, such as almonds, pecans, walnuts, or even a mix of several types of nuts. Alternately, honey or rice syrup might be used in place of the maple syrup in this recipe. Honey will provide a less sweet cake than maple syrup, whereas rice syrup will produce a cake that is sweeter than maple syrup. Add two tablespoons of strongly brewed organic espresso and two tablespoons of coffee grounds to the cake batter if you want the cake to have a coffee flavor. Crusted and broken cacao beans are what we call cacao nibs. Their slightly bitter chocolatey, nutty flavor adds another dimension and texture to chocolate puddings. Shop for them in natural food stores and large chain stores.
