  • 1 tsp vanilla extract

  • 1 large egg

For the White Chocolate Mousse:

  • 200g white chocolate, chopped

  • 1 1/2 cups cold heavy cream, divided

  • 1 tsp vanilla extract

  • 1 tsp unflavored gelatin (optional, for stability)

  • 2 tbsp cold water (if using gelatin)

For the Chocolate Ganache Topping:

  • 1/2 cup heavy cream

For Garnish:

Instructions

  • Make the Chocolate Cake Base:

    • Preheat oven to 350°F (175°C). Grease and line an 8×8 inch square pan.

    • Whisk together flour, cocoa, baking powder, baking soda, and salt.

    • In a separate bowl, combine sugar, oil, buttermilk, vanilla, and egg.

    • Mix wet and dry ingredients until smooth.

    • Pour into pan and bake for 20–25 minutes. Cool completely and level the top.

  • Prepare the White Chocolate Mousse:

    • (Optional) Bloom gelatin in cold water for 5 minutes.

    • Melt white chocolate with ½ cup cream until smooth. Stir in gelatin if using. Let cool to room temperature.

    • Whip remaining 1 cup of cream to stiff peaks. Fold into cooled chocolate mixture.

    • Spread over cake base and chill for 2–3 hours until set.

  • Make the Chocolate Ganache:

    • Heat cream to a simmer, pour over chopped chocolate.

    • Let sit 1 minute, then stir until smooth.

    • Cool slightly, then pour over mousse layer. Chill until ganache is set (about 1 hour).

  • Decorate:

    • Top with fresh strawberries and blueberries just before serving.

Notes

  • Use gelatin for a firmer mousse layer, especially if transporting.

  • Cake can be made a day ahead and stored in the fridge.

  • Slice with a warm knife for clean cuts.
