Roulade au Chocolat Pour Julia
- 1 1/2 cups plus 2 tablespoons granulated sugar
- 1 cup all-purpose flour
- 3/4 cup unsweetened cocoa powder
- 2 teaspoons baking powder
- 1 teaspoon baking soda
- 1/4 teaspoon salt
- 4 eggs, separated
- 3/4 cup vegetable oil
- 1/2 cup water
- 1 teaspoon vanilla extract
- 2 egg whites
- Chocolate-hazelnut mousse
- 1.
- Position the rack in the center of the oven and preheat the oven to 350 degrees.
- Butter or coat with vegetable spray a baking tray, 12 x 17 x 2 inches.
- Line with parchment paper and then spray the paper.
- Set aside.
- 2.
- Sift together 1 cup of the sugar, the flour, cocoa, baking powder, baking soda, and salt.
- Set aside.
- 3.
- In the large bowl of an electric mixer fitted with a paddle or beaters, beat the egg yolks at high speed.
- Turn the machine to low and pour in the oil, water, and vanilla.
- Gradually add the sifted ingredients and, when almost incorporated, turn the speed to medium and beat until well combined.
- 4.
- In another clean large bowl, with whip or clean beaters, whip the 6 egg whites until soft peaks form.
- Start on medium speed and raise the speed as the peaks begin to form.
- Gradually pour in the remaining 1/2 cup sugar and continue to whip until the whites are shiny and firm, but not stiff.
- With a rubber spatula, fold one-quarter of the whites into the chocolate mixture, then scrape the chocolate mixture back into the whites, quickly folding until completely incorporated.
- 5.
- Scrape into the prepared pan and spread with an offset spatula, smoothing and leveling the top.
- Bake until the edges of the cake pull away from the pan and the cake springs back when lightly pressed, 25 to 30 minutes.
- Cool on a rack.
- 6.
- When completely cool, place the pan on a firm surface.
- With a sharp knife, cut around the outside edges of the entire cake, separating the cake from the pan.
- Sprinkle 2 tablespoons of granulated sugar over the surface of the cake (to prevent sticking when you invert the cake).
- Invert a second baking tray on the top of the cake and flip the cake over onto the second tray.
- Carefully peel off the parchment paper, turn the paper over, and place back on the cake.
- Invert the cake and the paper so that the paper is on the baking tray and the sugared side is on top.
- You are now ready to spread the filling onto the cake.
- 7.
- Fill and roll the cake: Place the cake with one of the 17-inch sides directly in front of you.
- Using your spatula, spread 11 2 cups of the Chocolate-Hazelnut Mousse over the surface of the cake to the edge of three of the sides, leaving about a 1-inch space along the one side directly in front of you (see photo).
- Level the filling.
- Refrigerate the remaining mousse, covered.
- 8.
- Starting with the 17-inch side in front of you, using the parchment paper to help you, roll the cake toward the opposite side, completely enclosing the filling (see photo).
- Make certain that you do not roll the paper into the cake.
- Tuck the paper around the rolled cake to secure (see photo).
- Leave the cake on the pan and refrigerate until the filling is firm, at least 2 hours, up to overnight.
- 9.
- To serve, remove the cake from the refrigerator and unroll out of the paper onto a firm surface.
- Using a long serrated knife, cut a 2-inch diagonal piece off each end.
- With a #3 star tip fitted into a pastry bag, pipe 10 or 12 rosettes of mousse spaced evenly across the tip of the cake.
- Dust with sifted confectioners' sugar.
- Carefully transfer to a serving platter and refrigerate until needed.
- When ready to serve, cut into 10 or 12 portions.
- Pass the remaining mousse.
