Chocolate Genoise Cake Recipes

CHOCOLATE GENOISE

Steps:

• Heat oven to 350 degrees. Butter a 10 1/2-by-15 1/2-by-1-inch jelly-roll pan. Line with parchment; butter and flour paper, tapping out the excess flour.
• Sift flour, cocoa, and baking soda together twice into a medium bowl. Set aside. In a small saucepan over low heat, melt butter. Skim off white foam, and pour clear yellow butter into a bowl, discarding white liquid at the bottom. Set aside in a warm place.
• In a medium-size heat-proof bowl, whisk together eggs and sugar. Set bowl over a pan of simmering water; stir until mixture is warm to the touch and sugar has dissolved. Remove from heat, and beat on high speed until mixture is thick and pale and has tripled in bulk. Reduce speed to medium, add vanilla, and beat 2 to 3 minutes more.
• In three additions, sift flour mixture over egg mixture, folding in gently with a spatula. While folding in last addition, dribble melted butter over batter and fold in.
• Spread batter evenly in pan, leaving behind any unincorporated butter in the bottom of the bowl. Tap pan on counter to remove air bubbles. Bake until cake springs back when touched in center, 15 to 20 minutes. Don't overbake or cake will crack. Let sit in pan on a wire rack until cool enough to handle.
• Dust surface with cocoa powder. To make rolling easier, trim edges of cake, and cover with a sheet of waxed paper and a damp dish towel. Invert onto a work surface, and peel off parchment; dust with cocoa. Starting from one long end, carefully roll up cake in towel. Wrap in plastic; refrigerate until ready to use.

CHOCOLATE GENOISE

Steps:

• Place a 1-quart saucepan half filled with water over high heat and bring it to a simmer. Make a double boiler by setting a large mixing bowl over the simmering water. Place the whole eggs, egg yolks, sugar, and honey in the mixing bowl and make an egg foam by whisking the mixture to 113 degrees F (45 degrees C) on a candy thermometer, about 7 to 10 minutes. The egg foam passes through various stages becoming foamy, then smooth and finally it thickens. When it is thick, it will be hot to the touch, tripled in volume, and light in color and the sugar will have completely dissolved. If you dip the whisk into the mixture and pull it out, the batter should fall back into the bowl in a thick ribbon.
• Remove the mixing bowl from the heat and whip the batter with an electric mixer on medium-high speed until it cools, increases in volume, stiffens slightly and becomes pale yellow, about 7 to 10 minutes. Take the time to whip it well; if the mixture is underwhipped, the baked genoise will be dense. Very, very carefully, fold in the flour with a rubber spatula until the flour is no longer visible, making sure to fold to the bottom of the bowl. Do not overmix or the batter will deflate.
• I bake the genoise on a baking sheet 99 percent of the time because then I can cut it to any size I want. Spread the batter over a parchment paper-covered baking sheet and bake in a preheated 400 degrees F (200 degrees C) oven until lightly and evenly browned and springy to the touch, about 10 minutes. If using cake pans, fill buttered and parchment paper-lined 8-inch round cake pans three quarters full. Bake at 350 degrees F (175 degrees C) until well-risen and golden brown, about 30 minutes. Genoise is baked at a higher temperature for a shorter period of time on a baking sheet than when baked in a cake pan to allow it to retain moisture; if overbaked, it will be dry and crunchy.
• Let the genoise cool slightly. Unmold and finish cooling on a wire rack to allow the air to circulate evenly around the cake. The baked genoise can be stored in the freezer for 2 to 3 weeks if well wrapped in plastic wrap. Return it to room temperature before using it.
• VARIATION: You can easily make this recipe into a Chocolate Genoise by substituting unsweetened cocoa powder for 10 to 20 percent of the weight (a scant 1/4 cup to a full 1/3 cup/0.8 to 1.6 ounces/25 to 50 grams) of the flour. Weigh the cocoa powder before you sift it.
• SIDEBAR: Genoise can be made with butter. In this recipe, you can substitute butter (5 1/2 tablespoons, 2.7 ounces or 75 grams) for the 3 large egg yolks. Melt and cool the butter and fold it in after the flour is added.

CHOCOLATE GENOISE

Steps:

• One 9 by 2-inch round layer pan, or a 9-inch springform pan, buttered and the bottom lined with a disk of parchment or wax paper
• Set a rack at the middle level of the oven and preheat to 350 degrees.
• Sift together the cake flour, cornstarch, and cocoa through a fine-meshed strainer over a piece of waxed paper to break up any lumps in the cocoa. Set sifted ingredients aside with the strainer.
• Whisk together the eggs yolks, sugar, and salt in the bowl of an electric mixer. Place the bowl over a pan of simmering water and continue whisking gently until the mixture is lukewarm, about 100 degrees. This should take only a minute or two.
• Whip with the electric mixer on high speed until the mixture is cooled and increased in volume, about 3 to 4 minutes.
• Remove bowl from mixer and sift in dry ingredients, in three additions gently folding each third in with a rubber spatula. Pour the batter into the prepared pan and spread the top even with a spatula.
• Bake the layer about 30 minutes until it is well risen and the center is firm to the touch.
• If necessary, loosen the layer from the side of the pan with a small knife or spatula and invert the cake onto a rack. Place another rack on the cake and invert again. Remove the top rack, so that the layer cools right side up, still on the paper

PAUL'S GENOISE SPONGE

Steps:

• Heat oven to 190C/170C fan/gas 5. Brush 2 x 20cm cake tins with melted butter, line the bases with baking paper, then dust well with flour tipping out any excess. Set aside.
• Put the sugar and eggs in a large heatproof bowl, then set it over a pan of barely simmering water. Whisk with an electric hand whisk for about 7 mins or until the mixture is pale and has trebled in volume. Remove from the heat, then slowly pour in the butter folding it in as you pour until it is completely mixed in.
• Gently fold the flour and a pinch of salt into the egg mixture, then pour into your prepared cake tins. Cook for 25 mins until the cake is golden and risen - a skewer pushed into the cake should come out clean. Allow the cakes to cool for a few mins in the tin, then remove and cool completely on a wire rack.
• Meanwhile, whip the cream until it just holds its shape, then set aside. Whizz about a quarter of the strawberries with 1 tbsp sugar until smooth, then fold this purée through the cream so you get a ripple effect.
• To assemble the cakes, cut each one in half horizontally. Put one sponge on a serving plate, spread a quarter of the cream mix on top, then dot a quarter of the blueberries and raspberries around the edge. Repeat this step two more times, put the last layer of cake on top (save a top half of cake for the top layer), spread the remaining cream over, then put the blueberries and raspberries around the edge and pile the strawberries in the centre. Dust with icing sugar just before you serve.

GéNOISE CAKE

Steps:

• Preheat oven to 350°F, slide rack onto the lower-middle level, and prepare your pan (see below). Sift the flour with the 1 Tbs sugar and salt and reserve the clarified butter in a 2-quart bowl. Beat the eggs in your mixer bowl with the remaining sugar and the vanilla until you have "formed the ribbon." At once, rapidly sift on and fold in a quarter of the flour, then half the rest of the flour, and finally the last of it. Fold a large plop of this cake batter into the clarified butter, then fold the butter-batter back into the remaining batter. Turn batter into prepared pan, filling it to no more than 1/4 inch of the rim. Bang lightly on work surface to deflate bubbles, and bake 30 to 35 minutes, until puffed, lightly browned, and showing a faint line of shrinkage from sides of pan. Let cool 20 minutes before unmolding onto a rack. Let cool completely before filling and icing.
• SERVING SUGGESTION: WHITE MOUNTAIN CHOCOLATE-FILLED GÉNOISE. Prepare a double amount of the Italian meringue on page 102, and flavor half of it with chocolate, as directed. Using a long, serrated knife, cut the cake in half horizontally. Place bottom half on a rack set over a tray, and turn the top half cut side up. Sprinkle both surfaces with rum-flavored imbibing syrup (see page 101), and spread the chocolate meringue over the bottom half. Turn the top half cut side down over the filling, and frost the cake with the remaining white Italian meringue. Before serving, dust with a sprinkling of grated chocolate.
• CUP CAKES. Use the preceding génoise batter for cup cakes, following directions for almond cup cakes on page 98, which are some of my favorites with fruit desserts and tea.
• JELLY ROLL-ROULADE. Preheat oven to 375°F and set rack in lower middle. Grease the inside of an 11-by-17-inch jelly-roll pan with soft butter and line with a sheet of wax paper, leaving an extra 2 inches of it at each end; butter the paper where it lines the pan. Roll flour in the pan to cover inside and knock out excess. Spread in the génoise batter and bake about 10 minutes, until cake is lightly colored and top feels springy. Remove from oven. The following maneuvers are to prevent cake from cracking. Slice off 1/4 inch from each end of cake. Sprinkle top with confectioners' sugar. Cover with a sheet of wax paper and a slightly dampened towel. Set a tray over the top and reverse the two. Holding an end of the wax paper, lift off the jelly-roll pan. Then, very carefully, peel off the wax-paper backing. Sift a 1/8-inch layer of confectioners' sugar over the cake and roll it up in the damp towel; you may refrigerate it for a day or two. If frozen, be sure it has thoroughly defrosted before unrolling.
• Serving Suggestion: Apricot Roulade. Unroll the cake, sprinkle with imbibing syrup (see page 101), spread on the apricot filling (page 103), and frost with meringue butter cream (page 102).
• Smear inside bottom and sides lightly with softened butter. Cut a sheet of wax paper to fit bottom exactly, press it in place, and butter it. Pour 1/4 cup cake flour into pan, shake and turn in all directions to cover surface completely, turn pan upside down, and bang out excess flour.
• To avoid trouble, especially when making pastries, measure your flour accurately. For every recipe in this book, place the dry-measure cup on a large piece of wax paper. Scoop the flour directly into the sifter, and sift it directly into the cup until overflowing, then, using the flat edge of a big knife, sweep off excess flour level with the rim.
• When thoroughly cool, refrigerate in an airtight plastic bag for several days, or freeze for several weeks.

WHITE CHOCOLATE GENOISE (ITALIAN SPONGE CAKE)

Steps:

• Line the bottom of a greased 8 1/2 inch springform pan with wax paper, grease the paper and dust the pan with flour, knocking out the excess.
• In a metal bowl set over a pan of barely simmering water melt the white chocolate with the butter, the vanilla and 3 tablespoons water, stirring until the mixture is smooth.
• Remove the bowl from the heat and let the mixture cool.
• Into a bowl sift together the flour and the salt.
• In a large bowl with an electric mixer beat the eggs with the sugar on high speed for 5 minutes, or until the mixture is triple in volume and forms a ribbon when the beaters are lifted.
• Fold the flour mixture into the egg mixture until the batter is just combined and fold in the white chocolate mixture gently but thoroughly.
• Pour the batter into the pan, smoothing the top, and bake the cake in the middle of a preheated 350 degree oven for 25 minutes, or until a tester comes out clean.
• Transfer the cake to a rack, run a sharp knife around the edge, and remove the side of the pan.
• Invert the cake onto another rack and remove the wax paper.
• Reinvert the cake onto the rack and let it cool completely.

CHOCOLATE GENOISE FOR CHOCOLATE MOUSSE CAKE

Steps:

• Preheat oven to 400 degrees. Butter a 12-by-17-inch rimmed baking sheet, line with parchment paper, and butter the paper. Combine 1 tablespoon flour and 1 tablespoon cocoa, and coat the pan, tapping out excess. Place the egg yolks in the bowl of an electric mixer fitted with the whisk attachment. Beat on high speed until pale yellow, about 5 minutes. Transfer to a medium bowl, and set aside. Wash and dry the mixer bowl.
• Place the egg whites in the clean mixer bowl; with the whisk attachment, beat on medium speed until soft peaks form, about 3 minutes. Increase the speed to medium-high, and add the sugar gradually, until glossy stiff peaks form, about 3 minutes. Transfer the egg-white mixture to a large bowl.
• Using a rubber spatula, fold the egg-yolk mixture into the egg-white mixture. Sift the flour and cocoa powder over the top, and gently fold them into the batter. Gently pour the batter into the prepared baking sheet, and smooth the top with an offset spatula.
• Bake until cake springs back when touched, 10 to 12 minutes. Remove from oven; immediately turn cake out onto wire rack lined with parchment. Peel parchment from cake; cool completely. Use genoise the day it is made.
