Ingredients

Units Scale
  • 1 cup all-purpose flour
  • 1/2 cup unsweetened cocoa powder
  • 1 tsp baking powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • 1/2 cup unsalted butter, softened
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1/2 cup buttermilk
  • 1/2 cup hot water
  • 1 tbsp instant coffee (optional)
  • 200g dark chocolate, chopped (for mousse)
  • 1 1/2 cups heavy cream, chilled (for mousse)
  • 1/4 cup powdered sugar (for mousse)
  • 1 tsp gelatin (optional, for mousse stabilization)
  • 100g dark chocolate, chopped (for ganache)
  • 1/2 cup heavy cream (for ganache)

Instructions

  1. Preheat oven to 350°F (175°C). Grease and line a 9-inch springform pan.
  2. In a bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt.
  3. In another bowl, beat butter and sugar until light and fluffy. Add eggs one at a time, then mix in vanilla.
  4. Mix in half of the dry ingredients, followed by the buttermilk, then the remaining dry ingredients. Stir in hot water and coffee (if using).
  5. Pour batter into pan and bake for 25–30 minutes. Cool completely.
  6. For the mousse, melt dark chocolate and cool slightly. Whip the cream with powdered sugar to stiff peaks. Gently fold in melted chocolate. Optionally, bloom gelatin in 1 tbsp water, melt, and add to mousse for stability.
  7. Spread mousse over cooled cake and refrigerate for at least 2 hours.
  8. For ganache, heat cream until just boiling and pour over chopped chocolate. Let sit, then stir until smooth.
  9. Spread ganache over mousse layer and refrigerate until set, about 1 hour.
  10. Slice and serve chilled.

Notes

  • You can make the cake layer a day ahead for easier assembly.
  • Use good-quality chocolate for best results.
  • Add a dash of liqueur like Baileys or Kahlua to the mousse for a grown-up twist.
