Try our Classic Austrian Sacher Torte Recipe to savor tender, moist cake, decadent chocolate, and fruity apricot jam in each exquisite bite.
Preheat the oven to 350°F (180°C) and butter and line with parchment a 9-inch (23 cm) springform pan. Set aside.
In the bowl of a stand mixer fitted with a whisk attachment, whip the butter, salt and ½ cup (4 oz/115 g) sugar on medium-high until pale and fluffy, about 3 minutes.
Whip in the vanilla extract and then the egg yolks, one at a time, scraping down the sides of the bowl every now and then to ensure even mixing. Stir in the melted chocolate until combined.
Reattach the whisk and add the egg whites to the clean mixer bowl. Whip on high until soft peaks form, about 3 minutes. Gradually add the remaining ½ cup (4 oz/115 g) sugar and continue to beat to stiff, glossy peaks, a further 3-4 minutes.
Spread the batter into your prepared pan and bake for 50-55 minutes, until a cake tester inserted in the middle comes out clean.
Spread ½ of the jam on the bottom half of the cake then place on the top layer. Brush the top and sides of the cake all over with the remaining jam and let this set and dry, about 30 minutes.
Starting in the center of the cake, pour the chocolate in a circular motion over the top of the cake and let it drip down the sides. Tilt the wire rack a bit to encourage even spreading. If needed, use an offset spatula to smooth the sides. Let the glaze set until dry, for about 1 hour.
