DOUBLE BOILER PANS RECIPES

Steps:

• Grated chocolate, cookie crumbs or chopped nuts for coating the sides of cake, if desired
• Cake:
• Lightly coat the insides of 3 9 by 1 1/2-inch cake pans with melted butter. Line each pan with parchment paper, then lightly coat the parchment paper with more melted butter. Set aside.
• Preheat the oven to 325 degrees Fahrenheit.
• Heat 1-inch of water in the bottom half of a double boiler over medium heat. Place remaining butter and 8 ounces semisweet chocolate in the top half of the double boiler. Tightly cover the top with film wrap. Allow to heat for 10 to 12 minutes. remove from the heat, stir until smooth, and hold at room temperature.
• Place the egg yolks and 3/4 cup sugar in the bowl of an electric mixer fitted with a paddle. Beat on high until slightly thickened and lemon-colored, about 4 minutes. Scrape down the sides of the bowl and beat on high for an additional 2 minutes.
• While the egg yolks are beating, whisk 4 egg whites in a large stainless steel bowl until stiff, but not dry, about 3 to 4 minutes.
• Using a rubber spatula, fold the melted chocolate mixture into the beaten egg yolk mixture. Add a quarter of the beaten egg whites and stir to incorporate, then gently fold in the remaining egg whites.
• Divide the batter between the prepared pans, spreading evenly, and bake in the preheated oven until a toothpick inserted in the center comes out clean, about 25 to 30 minutes. Remove the cakes from the oven and allow to cool in the pans for 15 minutes. (During baking, the surface of the cakes will form a crust; this crust will normally collapse when the cakes are removed from the oven.) Invert the cakes onto cake circles, remove the parchment paper, and refrigerate for 30 minutes.
• Filling:
• To prepare the dark chocolate cream, heat 1-inch of water in the bottom half of a double boiler over medium heat. Place the semisweet chocolate in the top half of the double boiler. Tightly cover the top with film wrap and allow to heat for 8 to 10 minutes. Remove from the heat and stir until smooth. Transfer the melted chocolate to a stainless steel bowl and set aside until needed. Place heavy cream and sugar in the well-chilled bowl of an electric mixer fitted with a well-chilled balloon whip. Whisk on high until stiff peaks form, about 1 1/2 minutes. Remove the bowl from the mixer. Use a hand whisk to combine 1/4 of the whipped cream into the melted chocolate until smooth and completely incorporated. Add the combined whipped cream and chocolate to the remaining whipped cream and use a rubber spatula to fold together.
• Ganache:
• Heat the heavy cream and the butter in a 3-quart saucepan over medium high heat. Bring to a boil. Place the semisweet chocolate in a 3-quart stainless steel bowl. Pour the boiling cream over the chocolate and allow to stand for 5 minutes. Stir until smooth. Chill 1 cup of ganache for at least 1 hour. Remaining ganache should be at room temperature
• To assemble cake:
• Arrange one of the cake layers in a 9-inch springform pan, evenly spread half the filling over the cake and top with the second layer. Add remaining filling and top with the remaining cake layer. Chill 2 hours. Transfer chilled cup of ganache to pastry bag fitted with a star tip. Remove cake from springform pan and coat sides and top with room temperature ganache. Using chilled ganache, decoratively pipe stars on top of cake. If desired, coat sides of cake with grated chocolate, cookie crumbs of chopped nuts.

Steps:

• Heat the oven to 375 degrees.
• To make the cake, place the cocoa in a small bowl and whisk in the boiling water to form a paste. Combine the chocolate and milk in a saucepan over medium heat. Stir frequently as the mixture warms and the chocolate melts, about 3 minutes. Remove from heat. Whisk a small amount of the heated chocolate milk into the cocoa paste and then whisk the cocoa mixture into the milk mixture. Return to heat, stir for one minute, remove and cool until tepid.
• In the bowl of a mixer, cream the sugar and butter together. Beat in the egg yolks one at a time and add the vanilla. Slowly stir in the chocolate mixture.
• Combine the flour, baking powder, salt and baking soda. Using a spatula or a wooden spoon, slowly add the flour mixture to the chocolate mixture. In another bowl, whip the egg whites to form soft peaks and, using a rubber spatula, gently fold the egg whites into the batter.
• Butter and lightly flour two 8-inch round cake pans and divide the batter between the two pans. Bake for 45 minutes and cool on a rack for 15 minutes. Gently remove the cakes from the pans and continue to cool.
• While the cake is baking, make the filling. Put the cocoa into a saucepan and pour in the boiling water and place over low heat. Add the sugar and chocolate. Dissolve the cornstarch in the cold water to make a smooth paste. Whisk the cornstarch into the water and chocolate, add the salt and bring it to a boil, stirring constantly. Boil for one minute.
• Remove the pan from the heat, whisk in the vanilla and the butter, and transfer the mixture to a bowl and refrigerate until cool.
• Make the frosting. In a double boiler, melt the chocolate. Remove from heat and whisk in the butter, one tablespoon at a time, returning to heat if necessary to melt the butter.
• Whisk in the hot water all at once and stir until smooth. Whisk in the corn syrup and the vanilla. Refrigerate for 20 to 30 minutes before using.
• Assemble the cake. Use a sharp knife to slice each cake into two disks to form four layers. Set one layer aside. Place one layer on a cake round or plate. Generously swath the layer with filling. Add the second layer and repeat. Add the third layer. Quickly apply a layer of frosting to the top and the sides of the cake and refrigerate for 10 minutes. Meanwhile, crumble the remaining cake layer. Apply a second layer of frosting to the cake, press cake crumbs into the top and sides of the cake, and serve within 24 hours. Store in a cool place.
