Method
Preparation
- Preheat the oven to 350°F (175°C). Grease a 9-inch (23 cm) round cake pan and line the bottom with parchment paper.
- Melt 7 oz (200 g) dark chocolate in a double boiler or in 20–30 second bursts in the microwave, stirring until smooth. Let it cool slightly.
- In a bowl, cream together the room-temperature butter and 1/2 cup (100 g) of the sugar until light and fluffy (about 2–3 minutes). Stir in the vanilla extract and the slightly cooled melted chocolate.
- Add the egg yolks (one at a time) to the chocolate-butter mixture, mixing until combined.
- In a separate clean bowl, whisk the egg whites with a pinch of salt until soft peaks form. Gradually add the remaining 1/4 cup (50 g) sugar and continue whisking until glossy, stiff peaks form.
- Gently fold one-third of the beaten egg whites into the chocolate mixture to lighten it, then fold in the remaining whites carefully so you don’t deflate the batter.
- Sift the flour and baking powder together and gently fold into the batter until just incorporated. Don’t overmix.
- Pour the batter into the prepared pan and smooth the top. Bake for 40–45 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs (not wet batter). If the top browns too quickly, tent loosely with foil after 25 minutes.
- Let the cake cool in the pan for 15 minutes, then invert onto a wire rack and let it cool completely (about 30–40 minutes more).
Assembling
- Once cooled, slice the cake horizontally into two even layers using a long serrated knife.
- Warm and strain the apricot jam, then brush a generous layer onto the bottom cake layer. Place the top layer back on and brush the outside lightly with jam.
Glazing
- For the glaze: melt 4 oz (115 g) dark chocolate with 3 tbsp butter and the corn syrup/honey in a double boiler, stirring until smooth. If it’s too thick, add 1–2 tbsp hot water or coffee to loosen. Let it cool slightly so it’s pourable but not runny.
- Place the cake on a wire rack over a sheet of parchment. Pour the glaze over the cake, using an offset spatula to cover the sides. Work quickly before the glaze sets.
- Let the glaze set at room temperature for 30–45 minutes (or chill briefly for 10–15 minutes to speed up setting).
Notes
Best chocolate: Use good-quality dark chocolate (at least 60–70% cacao) for rich flavor. Storage: Keep covered at room temperature for up to 1 day, or refrigerate for up to 4 days. Freeze individual slices wrapped tightly in plastic and foil for up to 2 months. The cake layers can be baked a day ahead and assembled the next day; glazing day-of keeps the sheen fresh.
