Ingredients

For the Chocolate Cake

  • 300 g all-purpose flour
  • 75 g unsweetened cocoa powder
  • 2 tsp baking powder
  • 1 tsp baking soda
  • ½ tsp salt
  • 300 g granulated sugar
  • 3 large eggs
  • 180 ml vegetable oil
  • 240 ml buttermilk, room temperature
  • 180 ml hot brewed coffee
  • 2 tsp vanilla extract

For the Chocolate Ganache Filling

  • 300 g dark chocolate (60–70% cocoa), finely chopped
  • 300 ml heavy cream
  • 30 g unsalted butter

Optional Additions

  • 1 tsp espresso powder
  • ½ tsp cinnamon
  • 2 tbsp chocolate liqueur
  • Chocolate curls
  • Fresh raspberries
  • Chocolate sprinkles
  • Gold leaf for decoration
  • Sea salt flakes

Tips for Success

  • Use room-temperature eggs and buttermilk for a smooth batter.
  • Hot coffee enhances the chocolate flavor without making the cake taste like coffee.
  • Sift the dry ingredients to prevent lumps.
  • Do not overmix the batter once the flour is added.
  • Allow the cakes to cool completely before filling.
  • Chill the ganache until spreadable but still creamy.
  • Refrigerate the assembled cake for at least 2 hours before slicing for clean layers.

Instructions

  1. Preheat the oven to 350°F (175°C). Grease and line two 8-inch (20 cm) round cake pans with parchment paper.
  2. In a large bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt.
  3. In another bowl, beat the sugar, eggs, vegetable oil, buttermilk, and vanilla extract until smooth.
  4. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
  5. Slowly stir in the hot coffee until the batter is smooth. The batter will be thin.
  6. Divide the batter evenly between the prepared cake pans.
  7. Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
  8. Let the cakes cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely.
  9. Meanwhile, heat the heavy cream until it just begins to simmer.
  10. Pour the hot cream over the chopped dark chocolate and let stand for 2–3 minutes.
  11. Add the butter and stir until the ganache is smooth and glossy.
  12. Allow the ganache to cool until it reaches a spreadable consistency.
  13. Place one cake layer on a serving plate and spread a generous layer of ganache over the top.
  14. Add the second cake layer and cover the top and sides with the remaining ganache.
  15. Refrigerate the cake for 2 hours before serving.
  16. Slice and enjoy.
