Ingredients
For ingredients and detailed instructions, refer to the recipe card below.
- Large eggs at room temperature. Bring them to the counter about an hour before you start. You can also immerse eggs in shells in warm water for a few minutes.
- Granulated sugar
- All-purpose flour: You can omit the flour mixed with cornstarch and choose cake flour.
- Cornstarch lightens the gluten in the AP flour and helps improve the cake's texture.
- Unsweetened cocoa powder: Opt for Dutch process cocoa for the darker, more bittersweet experience.
- Unsalted butter
- Dark chocolate with a cocoa content of 70%. The taste of the ganache depends mainly on the quality of the chocolate. I highly recommend selecting top-quality chocolate bars or chocolate callets (for example, Callebaut chocolate chips). But avoid your favorite chocolate chips used for baking.
- Heavy cream or heavy whipping cream with at least 30% fat content.
How to make chocolate ganache cake
Step 1. To make chocolate sponge cake, preheat the oven to 355°F (180°C). Grease an 8-inch pan (20 cm in diameter) with softened butter and a pastry brush.
Pro tip: Consult the chocolate Genoise recipe for step-by-step photographed explanations, helpful tips, and tricks.
Step 2. Sprinkle the buttered tin with a tablespoon of flour and gently shake and tilt the pan. Tap the pan against the sink upside down to remove any excess flour.
Pro tip: Alternatively, brush the baking tin with softened butter or use cooking spray, then line the bottom and sides of the pan with parchment paper.
Step 3. In a large mixing bowl, sift flour and cocoa powder a couple of times. Then, in a heatproof bowl or the bowl of a stand mixer, beat eggs with sugar with a hand whisk until frothy (photo 1).
Step 4. Bring the bowl over a water bath or bain-marie and warm the mixture to 104°F (40°C), whisking constantly.
Step 5. Remove the bowl from the heat and whisk eggs and sugar with a stand or an electric hand mixer for 10 minutes (longer if an electric mixer is used). The mixture will whiten and triple in volume and reach the ribbon stage (photo 2).
Step 6. Sift the flour and cocoa mixture over the bowl in a few additions and gently fold in using a rubber spatula.
Step 7. Pour the cake batter into the prepared baking pan (photo 3) and bake for 30-35 minutes.
Step 8. Remove the cake from the oven and let it cool in the pan for 10 minutes (photo 4). Then, invert the pan and let the cake slip on a cooling rack. Let it cool down completely.
Step 9. To make sugar syrup, pour water and sugar into a saucepan and bring it to a boil. Remove the pot from the heat, add cocoa powder, and mix well with a mini whisk. Let it cool.
Step 10. To make chocolate ganache, chop the dark chocolate bar (or use chocolate callets) and place it in a bowl. Alternatively, use a food processor to crush chocolate.
Step 11. Pour heavy cream into a small saucepan and bring it over medium heat, stirring with a hand whisk. Warm the cream to 176°F (80°C), then pour half over the chocolate (photo 5).
Step 12. With a wooden spoon, mix chocolate with cream gently from the center to the edges. Then add the remaining hot cream and stir until shiny and smooth (photo 6).
Step 13. Leave to cool slightly, stirring occasionally, or film it in contact and let it set at room temperature. The ganache has to reach the spreadable stage.
Pro tip: You can film the ganache on contact and set it aside in the fridge. But make sure to stir it each 5 minutes, and don't miss the right consistency to assemble the cake.
Step 14. To assemble the cake, slice the cooled cake into three cake layers using a serrated knife or a cake leveler. Place the bottom layer onto a cake board, parchment, or serving plate and spread a â…– inches (1 cm) thick layer of ganache (photo 7).
Pro tip: It takes about 6.4 oz. (180 g) of chocolate ganache for each layer.
Step 15. Repeat this process with the second, covering it completely with a ganache. Finally, place the third layer on top to complete the cake (photo 8).
Step 16. Use an offset spatula to frost the sides and top of the cake with the remaining ganache. Let the cake stay at cool room temperature to set the ganache.
