Lisbon Chocolate Cake Recipes

Steps:

• Make the cake: Center a rack in the oven, and heat oven to 325 degrees. Butter a 9-inch cake pan, line with parchment paper and butter the paper.
• Sift together the cocoa powder, cornstarch, baking powder and salt in a medium bowl. Whisk to blend.
• Put the 1/2 cup butter in a large heatproof bowl set over a saucepan of simmering water. Scatter the semisweet or bittersweet chocolate on top, and heat, stirring often, until the mixture is smooth and glossy. Remove the bowl from the pan, and stir in the sugar. One by one, energetically stir in the eggs, beating for 1 minute after the last egg is added. The mixture will look like pudding. Stir in the dry ingredients. Scrape the mixture into the cake pan, and give the pan a couple of good raps against the counter to settle the batter.
• Bake for 18 to 20 minutes, or until a tester inserted into the center comes out clean (or with only a tiny streak of chocolate). Transfer to a rack, cool for 5 minutes, then unmold the cake. Peel off the paper, invert the cake and cool to room temperature. Wash and dry the cake pan.
• Make the ganache: Pour 1 1/4 cups cream into a small saucepan; refrigerate the rest. Scald the cream over medium heat, turn off the heat and stir in the semisweet or bittersweet chocolate until fully incorporated. Transfer to a heatproof bowl. Refrigerate the ganache for 10 minutes, whisk it, then refrigerate again for 10 minutes. Repeat chilling and whisking steps until the ganache is thick enough to make tracks when you stir, 50 to 60 minutes.
• Cut two 3-by-16-inch pieces of parchment or foil, and crisscross them in the cake pan. Carefully return the cake to the pan. (The mousse layer is too soft to stand on its own until it's chilled. It needs the support of the pan sides.)
• Whip the remaining 1/2 cup cream until it holds medium peaks.
• Using a whisk, gently beat the ganache until it's soft and spreadable. With a spatula, fold in the whipped cream. Spread over the cake, and refrigerate for 2 hours (or cover and keep for up to 2 days). The cake is best served cool or at room temperature, so take it out of the fridge about 20 minutes before serving.
• To finish, put the cocoa powder in a fine-mesh strainer, and shake it over the top of the cake. Run a table knife along the sides of the pan. Using the parchment or foil handles, carefully lift the cake out of the pan and onto a serving plate. Discard the strips. Cut the cake using a long knife that has been run under hot water and wiped dry between each cut.

Steps:

• Heat oven to 350 degrees Fahrenheit/170 degrees Celsius. Grease a 9-inch/23-centimeter round springform pan with butter and line with parchment paper, then set aside.
• Make the cake: Place butter, chocolate and hot coffee in a large heatproof bowl and mix well until everything is melted, combined and smooth. Whisk in sugar by hand until dissolved. Add eggs and vanilla extract and whisk again until thoroughly combined and smooth. Sift flour, cocoa powder and salt together into a bowl and then whisk this into the melted chocolate mixture. The batter here is liquid, but don't think you have missed something; this is how it should be.
• Pour batter into the prepared pan and bake for 1 hour, or until the cake is cooked and a skewer inserted into the center comes out clean or with just a few dry crumbs attached. The top will form a crust and crack a little, but don't worry, this is expected. Leave the cake to cool for 20 minutes before removing from the pan, then set aside until completely cool.
• Make the chocolate ganache, if desired: Place chocolate pieces in a food processor, process until fine and set aside. Combine cream and corn syrup in a small pan and place over medium-high heat. As soon as bubbles begin to appear (just before it comes to a boil), remove from the heat. Get the food processor running again, with the chocolate still inside, and pour in the hot cream in a steady stream. Process for 10 seconds, then add butter. Continue to process until mixture is shiny and smooth. (You can also make the ganache by hand; just make sure the chocolate is chopped fairly finely before adding the cream mixture. Stir with a wooden spoon until almost melted, then add the butter. Stir again until the ganache is smooth.)
• Use a rubber spatula to scrape the ganache into a bowl and cover with plastic wrap, with the plastic actually touching the top of the ganache. Set aside until it has set to the consistency you want. If you want a thin layer to spread over the cake, it can be poured over while liquid so that you get an even, light and shiny coating. For a thicker ganache with a spreading consistency, leave it for about 2 hours at room temperature. (The ganache can be stored at room temperature, providing it's not too warm, for 3 days or kept in the fridge for up to 2 weeks. It can also be frozen, although it will lose a bit of its shine when defrosted.)
• Make the espresso cinnamon mascarpone cream, if desired: Place all the ingredients in the bowl of an electric mixer fitted with the whisk attachment. Beat for 1 to 2 minutes, until soft peaks form.
• Peel the parchment from the cake and discard. Transfer to a serving platter and spread the ganache, if using, on top of the cake. Slice into wedges, divide the cake among plates and, if using, spoon the mascarpone cream alongside. With or without icing, the cake will keep well for 4 to 5 days in an airtight container.
