Instructions
- Preheat oven to 350°F (175°C). Grease and line a 9-inch springform pan.
- In a bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt.
- In another bowl, beat butter and sugar until light and fluffy. Add eggs one at a time, then mix in vanilla.
- Mix in half of the dry ingredients, followed by the buttermilk, then the remaining dry ingredients. Stir in hot water and coffee (if using).
- Pour batter into pan and bake for 25–30 minutes. Cool completely.
- 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.
- Spread mousse over cooled cake and refrigerate for at least 2 hours.
- For ganache, heat cream until just boiling and pour over chopped chocolate. Let sit, then stir until smooth.
- Spread ganache over mousse layer and refrigerate until set, about 1 hour.
- 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.
