Ingredients
Method
To Make the Cake:
- Preheat your oven to 170°C (340°F). Grease a round cake pan and line the bottom with parchment paper.
- In a stand mixer with a whisk attachment, whip the eggs, sugar, salt, and vanilla extract until the mixture is light and airy.
- Add the sour cream and vegetable oil. Mix on medium speed until well combined.
- Sift the flour, cocoa powder, and baking soda into the bowl. Mix gently until the batter is nearly smooth.
- Gradually pour in the lukewarm water while mixing, and continue mixing until the batter is fully combined and smooth.
- Pour the batter into the prepared cake pan.
- Bake for 50 to 60 minutes, or until the cake is set and a skewer inserted comes out with moist crumbs.
- Let the cake cool completely in the pan. Once cooled, remove from the pan and slice horizontally into two even layers.
To Make the Ganache:
- Place the chopped dark chocolate in a heatproof bowl.
- Heat the cream in a saucepan or microwave until just boiling, then pour it over the chocolate.
- Let it sit for a minute, then stir until smooth and glossy.
- Allow the ganache to cool at room temperature for 4 to 5 hours, or refrigerate and stir occasionally until it thickens to a spreadable consistency.
To Assemble the Cake:
- Place the bottom cake layer on a serving plate.
- Spread one-third of the ganache evenly over the cake.
- Top with the second cake layer.
- Cover the top and sides of the cake with the remaining ganache.
- Pipe any extra ganache over the top using a piping bag with a serrated tip for decoration.
- Serve the cake at room temperature for the best texture.
- Store leftovers in an airtight container for up to one week. Let it come to room temperature before serving if chilled.
Notes
- For an extra moist cake, wrap the cooled layers in plastic wrap and refrigerate overnight before assembling.
- You can use semisweet chocolate instead of dark chocolate for a milder ganache.
- This cake pairs wonderfully with fresh berries or a scoop of vanilla ice cream.
