Posted by threeovens. Serve with whipped cream if desired.
- For the cake:
- 5 ounces bittersweet chocolate, finely chopped (use good quality)
- 9 tablespoons unsalted butter, room temperature
- 1 cup powdered sugar
- 6 large eggs, separated (room temperature)
- 1 teaspoon pure vanilla extract
- 1/2 cup caster sugar
- 1 cup all-purpose flour
- Apricot glaze:
- 1 1/4 cups apricot preserves
- 2 tablespoons golden rum or 2 tablespoons water
- Chocolate glaze:
- 1 cup sugar
- 1/2 cup water
- 4 ounces bittersweet chocolate
- Preheat your oven to 400 degrees F and position the rack to the center of the oven. Lightly butter a 7-inch springform pan and line with parchment: dust the sides with flour and tap out any excess.
- In a double-boiler, melt the chocolate over simmering water; remove from heat and stir until cooled.
- In a stand mixer fitted with the paddle attachment, beat the butter using medium-high speed until smooth, about 1 minute. Switch to low speed, beat in the powdered sugar, then return to medium-high, and beat until fluffy and lighter in color and texture, about 2 minutes.
- Beat in the egg yolks first, one at a time, scraping down the sides of the bowl; beat in the chocolate and the vanilla.
- In another large bowl, beat the egg whites with the castor sugar, using high speed, until they form soft, shiny peaks.
- Stir 1/4 of the egg whites into the chocolate mixture, then fold in the remaining, leaving some strips of white showing.
- Sift half the flour over the chocolate, then fold in; repeat with remaining flour.
- Spread the batter evenly into the prepared pan and bake until a wooden toothpick inserted into the center comes out clean, about 45 minutes.
- Cool on a wire rack for 10 minutes, then remove the sides of the springform pan and invert the cake onto the rack, remove the paper and re-invert to turn right side up and let cool completely.
- Meanwhile prepare the glazes. For the apricot glaze: In a small saucepan, bring the preserves and rum (or water) to a boil over medium heat, stirring often; cook, stirring, until very sticky and does not easily leave the spoon, 2 to 3 minutes. Strain through a wire sieve, pressing on the solids. Use warm.
- Use a serrated knife to trim the top of the cake to make it level; cut the cake horizontally to make two even layers.
- Place the bottom layer on an 8-inch cardboard cake round; brush the top of the layer with half the warm apricot glaze. Place the second layer on top, then brush with the remaining glaze; transfer the cake to a wire rack that has been set over a jellyroll pan (to catch drips) and let the glaze set.
- For the chocolate glaze: In another small saucepan, heat the sugar, water, and chocolate to a boil over medium-high heat, stirring occasionally. Reduce the heat to medium and cook, uncovered, stirring, until it reaches 234 degrees F on a candy thermometer, about 5 minutes. Remover from heat and stir to cool for about 1 minute. Use immediately and do not scrape the pan (the chocolate that clings to the saucepan will not be a glaze, it is too thick).
- Pour the warm chocolate glaze over top and use an offset spatula to gently spread the glaze all over, including the sides, so that the cake is completely covered; use any glaze that drips to patch missed spots.
- Once glaze has begun to set, place cake on a serving platter and cool completely in the refrigerator at least an hour; let the cake stand at room temperature 1 hour before serving.
- If desired, serve with a saucer of unsweetened whipped cream for dipping.
