About this Recipe

It’s no secret, a lot of my cooking and baking is inspired by my childhood. As a kid growing up in Vienna, I have fond memories of my grandmother and mother baking and creating beautiful and delicious dishes. The bakeries in Austria create little dessert wonders with a lot of history and technique. This specific Hazelnut cake recipe is inspired by a cake I tasted during a night out with my parents. I haven’t found the recipe anywhere else so I recreated it to the best of my taste buds memories.

How to make Hazelnut Cake

This is by no means a difficult recipe, I will break it in to three easy to follow steps. As always, If you have any questions, post them in the comments and I will answer them the soonest. This way other readers can also benefit from your question and my answers.

Step One: Hazelnut Sponge Cake

Start by creaming the egg yolks with 3/4ths of the sugar and the cinnamon until light and fluffy. Lightly whisk in the lemon juice. Set aside and whisk the egg whites with the pinch of salt and the remaining sugar to stiff peaks.

Pour over the egg whites, add the ground hazelnuts, ground chocolate and carefully fold together. Use a rubber or wooden spatula to avoid deflating the egg whites. Line a baking tray with baking paper and grease with butter or margarine. Pour the batter in to the tray and carefully flatten with the rubber spatula.

Note: Its important that you grease the paper as this dough is quite sticky and can easily break.

Bake at 190 C or 375 F for 25 to 35 minutes. The sponge cake should be golden brown. Place on a cooling rack and carefully remove the parchment paper. If the paper is stuck, don’t worry. Use a long knife and slice carefully while peeling off the paper. Let it cool while we prepare the hazelnut cake filling.

When the sponge cake has cooled, trim the edges using a long knife. Then cut into even slices. My cake turned out 35 x 25 centimeters or apx 14 x 10 inches so I cut it into 5cm / 2 inch wide slices. Simply divide the length by the amount of slices and you will get the width of each sliced to cut. Length wise I cut the sponge in half, if you want to make more portions, simply split it by 4 and make smaller hazelnut cake slices.

Half of the cut slices will be the bottom of the cake or cake slice so set aside until we make the hazelnut cake filling.

Step Two: Hazelnut Cake Filling

The Hazelnut Cake filling is simple, and because we don’t want to overpower the flavour, it is a simple vanilla heavy cream. So whisk the heavy cream with the sugar and vanilla sugar until stiff. Fill in a piping bag with a star attachment and spread an even layer on the bottom slices or cake. Now top with the other half of the slices and make a cake sandwich. Careful don’t squash the cream 🙂

Step Three: Chocolate Ganache & Decoration

For the topping we will make a simple chocolate ganache drip. There are two options when making the ganache, you can make a crunchy chocolate top which is a mixture of chocolate and coconut oil. But if you want to make a soft ganache that is not crunchy, then we add about 1/2 a cup of heavy cream.

I prefer the crunchy top, as its very thin it’s easy to cut and has a nice additional texture. Simply melt the chocolate with the coconut oil over a bermarie. If you want to temper the chocolate to give it a nice satin finish, keep around 20% of the chocolate aside. Once the chocolate has melted, take if of the heat and stir in the remaining chocolate until it has dissolved.

Peeling Hazelnuts

To avoid the chocolate cover coming off our hazelnuts as well as a bitter taste from the hazelnut skins, we will peel them. To peel hazelnuts, spread them evenly on a baking tray and bake them for 8-10 minutes at around 170 C. Then place them in a kitchen towel and rub them together until all the skin comes off. Set aside to cool and then proceed with the next step.

Now dip the hazelnuts and set them on parchment paper to dry. Using a tablespoon, carefully cover the hazelnut cake slices with chocolate ganache. Give it a little drip here and there to make them look even more delicious.

When the ganache has dried, pipe three dots of the cream filling diagonally across each slice. Then top with a chocolate dipped hazelnut.

Storing

This cake is best served fresh, you can however store it in the fridge for 3-4 days. Place it in an airtight container to avoid cross contamination and fridge odors. I have tried freezing this cake and while it still tastes great, it’s a lot nicer fresh. You can NOT freeze the dough as the eggs will deflate and you will end up with a chewy cake.

Vanilla Heavy Cream

  • Combine the heavy cream, sugar and vanilla sugar and whip to stiff peaks. Apply a thick layer using a piping bag. If you don't have a piping bag, simply spoon on and level.

Chocolate Ganache

  • set 1/5 of the chocolate aside and melt the remaining chocolate with the coconut oil over a slow simmering bermarie. Once fully dissolved take off the heat and add the remaining chocolate. Stir until dissolved. Dip the decorative hazelnuts in chocolate and set on a piece of parchment paper to dry.
  • Using a tablespoon, drip 1-2 full tablespoons over each slice. Allow the sides to drip a little. Once the chocolate has set, pipe three diagonal spots on each slice and top with chocolate dipped hazelnuts. Enjoy as fresh as possible.

Notes

You can add heavy cream to the chocolate ganache to make it soft otherwise it will remain brittle.
