Instructions
Preheat oven to 350°F (177°C). Line a 9-inch springform pan with parchment and lightly grease the sides.
In a bowl, whisk together flour, sugar, cocoa powder, baking soda, baking powder, and salt.
Stir in oil, egg, vanilla, and buttermilk until combined.
Slowly add hot coffee, whisking until batter is smooth (it will be thin).
Pour into the prepared pan and bake for 25–30 minutes. Test with a toothpick. Cool completely.
Melt chocolate chips for mousse, then let cool slightly.
Whip heavy cream until soft peaks form. Add powdered sugar, vanilla, and espresso powder.
Gently fold cooled melted chocolate into the whipped cream to form mousse.
Spread mousse evenly over cooled cake. Chill for 2–3 hours.
Heat cream for ganache until steaming. Pour over chocolate chips. Whisk until smooth.
Spread ganache over mousse. Add raspberries and espresso beans for garnish.
Chill, slice, and serve.
Notes
Use freshly brewed hot coffee to enhance the chocolate flavor.
The cake can be made a day ahead for easier assembly.
Always cool the sponge fully before adding mousse to prevent melting.
