Plum Hazelnut Chocolate Cake Recipes

Steps:

• For the dough: Warm the milk until just warm to the touch (90 to 100 degrees F). Stir in the yeast and a pinch of the granulated sugar and let sit until foamy, about 5 minutes. Combine the flour, remaining granulated sugar and the kosher salt in a stand mixer fitted with the paddle attachment. Mix on low speed to combine. Separate 1 of the eggs and set aside the white for the egg wash. Whisk the egg yolk and remaining whole egg into the yeast mixture. Add the yeast mixture to the flour, then mix on low speed to make a smooth, thick dough. Increase the speed to medium and add the butter a piece at a time. Once all of the butter has been added, beat on high until smooth, about 1 minute. Switch to the dough hook and knead the dough until it forms a smooth, springy ball on the hook, 4 to 5 minutes (add a little more flour, if needed, if the dough doesn't form a ball). Grease a large bowl and turn the dough in the bowl to coat. Cover and let rise at room temperature until doubled, 1 to 2 hours.
• For the custard: Meanwhile, in a large saucepan, combine the cream, granulated sugar, cornstarch, kosher salt, egg and yolk. Whisk it together and heat over medium heat until thick, 4 to 5 minutes. Remove from the heat and add the butter and extract; stir until combined. Transfer to a clean bowl. Cover the surface of the custard with plastic wrap. Let cool at room temp.
• Line 2 baking sheets with parchment paper. Cut the dough in half, then cut each half into 6 equal pieces. Working with one piece at a time, form the dough into balls by folding the dough under itself and pinching to seal underneath. Set the ball, smooth-side up, on a floured surface, and turn in your hand to form a tight round shape. Divide the 12 buns among the lined baking sheets. Cover loosely with plastic wrap and let rise until doubled, about 30 minutes. Preheat the oven to 350 degrees F.
• Once the buns have risen, gently press down on each to make indentations that will make space for the custard. Fill the indentations with the custard. Top with the plums. Brush the buns with the reserved egg white mixed with a splash of water and sprinkle with demerera sugar, a pinch of cinnamon and flakey salt. Bake, rotating the trays from top to bottom halfway through, until the buns are risen and golden and the custard is set, 18 to 22 minutes. Transfer to a wire rack to cool.

Steps:

• Heat oven to 180C/fan 160C/gas 4. Butter and line the base of a round 20cm cake tin. Halve and stone 4 plums, set aside for later, then roughly chop the remaining plums.
• Put the sugar, butter, flour, ground hazelnuts, eggs and baking powder into a large bowl and beat with a wooden spoon or electric hand mixer for 1-2 mins, until smooth and light. Stir in the chopped plums and chocolate, then tip into the prepared cake tin and smooth the top.
• Arrange the halved plums over the top of the mixture, pressing them down lightly, then scatter over hazelnuts. Bake for 40-50 mins until the top is golden and the cake feels firm to the touch. Cool in the tin for 10 mins, then turn out, remove the paper and cool on a wire rack. Heat the jelly, then brush over the top of the cake before serving.

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:

• Preheat oven to 350°F. Butter bottom and sides of springform pan and line bottom with parchment.
• Purée plums in a blender until very smooth (you need 1 1/2 cups; reserve any additional purée for another use). If plums are not ripe enough to form a very smooth purée, strain through a fine-mesh sieve.
• Combine chocolate and 3/4 cup butter in a large heatproof bowl. Set bowl over a medium saucepan of barely simmering water (do not let bowl touch water). Stir until chocolate is melted and smooth. Remove bowl from saucepan. Stir plum purée into chocolate mixture until well combined.
• Using an electric mixer on medium speed, beat eggs and sugar in another large bowl until pale and tripled in volume, 10-12 minutes. Using a rubber spatula, fold about 1/3 of the egg mixture into chocolate mixture to lighten, then fold chocolate mixture into remaining egg mixture until combined.
• Combine flour, baking powder, and salt in a medium bowl, then fold dry ingredients into chocolate mixture until combined.
• Pour batter into prepared pan and smooth surface. Bake cake until center is set and sides are beginning to brown, 45-55 minutes. Transfer to a wire rack and let cake cool completely in pan (cake will sink a little in the center as it cools).
• Meanwhile, using an electric mixer on medium-low speed, beat cream in a large bowl until soft peaks form. Unmold cake (run a knife around the edge to help release, if needed) and transfer to a platter. Mound whipped cream in center of cake, then dust with cocoa powder.

Steps:

• Preheat oven to 425°F. and butter and flour an 8-inch round cake pan, knocking out excess flour.
• In a small saucepan melt butter over moderate heat and cool. Stir in vanilla. In a food processor blend together nuts, brown sugar, and flour until nuts are ground fine.
• In a bowl with an electric mixer beat whites with salt until they hold stiff peaks and fold in nut mixture gently but thoroughly. Fold in butter mixture (batter will deflate) and spread batter in prepared pan.
• Arrange plum slices evenly over batter and sprinkle with granulated sugar. Bake cake in middle of oven 20 to 25 minutes, or until a tester comes out clean. Turn cake out onto rack and cool, plum side up, 5 minutes.
• Sift confectioner's sugar onto cake and serve cake warm with ice cream.
