Ingredients
  

For the Chocolate Cake
  • 1 cup all-purpose flour
  • 1 cup granulated sugar
  • 1/2 cup unsweetened cocoa powder
  • 1 tsp baking powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • 1/2 cup unsalted butter, melted
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1 cup buttermilk
For the Chocolate Mousse
  • 1 cup semisweet chocolate chips
  • 2 cups heavy cream, divided
  • 1/4 cup powdered sugar
  • 1 tsp vanilla extract
For the Garnish
  • Chocolate shavings or curls Optional
  • Fresh berries Optional, but they make everything fancy!

Method
 

Bake the Cake
  1. Preheat your oven to 350°F (175°C). Grease and flour an 8-inch round cake pan.
  2. In a large bowl, mix together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
  3. Add the melted butter, eggs, vanilla, and buttermilk. Mix until well combined, taking care to leave some lumps.
  4. Pour the batter into the prepared pan and bake for 25-30 minutes, or until a toothpick inserted comes out clean.
  5. Let it cool completely before removing it from the pan.
Prepare the Mousse
  1. In a heatproof bowl, melt the semisweet chocolate chips using a microwave or a double boiler. Stir until smooth and set aside to cool slightly.
  2. In another bowl, beat 1 cup of heavy cream with powdered sugar and vanilla until soft peaks form.
  3. Gently fold the melted chocolate into the whipped cream until fully incorporated.
  4. Repeat the process for the remaining cup of heavy cream.
Assemble the Cake
  1. Place the cooled chocolate cake on a serving plate. Spoon half of the chocolate mousse over the top, spreading it evenly.
  2. Layer the remaining mousse on top and spread it beautifully.
  3. Chill in the fridge for at least two hours to allow flavors to meld.
Serve and Garnish
  1. Top with chocolate shavings or fresh berries before serving.
  2. Cut into slices and enjoy every bite.

Notes

If short on time, make the mousse a day ahead and chill. Don't worry if the mousse is a bit lumpy; gentle folding will help. Experiment with add-ins like espresso powder for enhanced chocolate flavor.
