Author Notes: I can’t think of a more Italian flavour for desserts then chocolate, hazelnuts and coffee. I love anything with hazelnuts and the combination with coffee and chocolate are my favourite. This cake is not very sweet and the coffee added makes it a real subtle dessert. I like baking this cake in a tray and plating the dessert in single portions. But it can be made as a cake in layers as well. - Maria Teresa Jorge
Chocolate, Hazelnut and Coffee Cake
- 7.8 ounces 70% cocoa chocolate (Valrhona or similar)
- 5.5 ounces butter cut up in small pieces at room temperature
- 1 1/2 cup fine sugar
- 2 tablespoons confectioner’s sugar for egg whites
- 7.5 ounces ground toasted skinned hazelnuts
- 1/4 cup all purpose flour
- 1/4 cup potato starch
- 2 teaspoons baking powder
- 6 eggs at room temperature
- 2 tablespoons Instant coffee
- 1 Vanilla bean
- 1 pinch salt
- 4 egg yolks
- 1 cup single cream
- 1 cup strong espresso coffee
- 1/2 cup sugar
- 1/3 cup all purpose flour sifted twice
- 3/4 cups whipping cream
- Make the custard first: Make the espresso. In a pan, bring the single cream and the espresso to a boil.
- Beat the egg yolks and the sugar until pale. Add the sifted flour and incorporate well.
- Pour the milk and espresso in a stream over the yolks, sugar and flour mixture and continue beating until well incorporated. Scrape the bottom and the sides, mix well. Return to the pan and cook over low heat, stirring continuously for 3 to 5 minutes. Cool to room temperature.
- Whip the cream and add to the cold custard. Cover with plastic film and chill.
- Cake: Pre-heat the oven to 350º F with rack in the middle position.
- Butter a rectangular baking tray. Cut a piece of parchment paper the size of the bottom of the tray and adhere it to the butter. Butter and flour the parchment paper and sides of the tray.
- Toast the skinned hazelnuts until golden brown, cool them completely and process them finely.
- Cut the chocolate in pieces and melt in a pan over a bain-marie. Remove the pan and put it on a cold surface to lower the temperature of the chocolate.
- Open the vanilla bean and scrape out the seeds.
- In a stand mixer fitted with the paddle attachment, beat the soft butter with the sugar and vanilla until pale and fluffy.
- Add the 6 egg yolks, one at a time, and the cooled melted chocolate beating well.
- Sift the flour, potato starch and the salt together and fold it in the above mixture. Add the ground hazelnut.
- Whisk the egg whites and half way through add the 2 tablespoons of confectioner’s sugar and continue beating to hard peaks. Fold the egg whites in 3 parts in the cake mixture, very gently.
- Pour the cake mixture in the baking tray and smoothen the top so it bakes evenly. Bake for 25 to 30 minutes or until golden brown.
- Cool for 5 minutes in the pan and then invert on a wire rack and peel the parchment paper. Allow to cool completely before cutting.
- When completely cold, use a serrated knife to cut in rectangles or whatever shape you prefer.
- Assembling the cake: Cut rectangles all the same size, and then cut them in the middle horizontally so you have thin layers of cake. Use 3 layers per serving. Start with a cake layer, Cappuccino custard, cake layer, cappuccino custard, cake layer and finish with Cappuccino custard. Dust some cocoa powder around the plate and garnish with roasted hazelnuts.
