Instructions

Bake the Chocolate Cake

  • Preheat your oven to 350°F (175°C) and prepare two 9-inch round cake pans by greasing and lining them with parchment paper.
  • In a mixing bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt.
  • In another bowl, combine granulated sugar, brown sugar, vegetable oil, eggs, vanilla extract, and buttermilk. Mix until smooth.
  • Gradually add the dry ingredients to the wet mixture, followed by hot coffee. Stir gently.
  • Divide the batter between the prepared pans and bake for 20-25 minutes until a toothpick comes out clean.
  • Allow the cakes to cool completely in the pans before transferring to wire racks.

Prepare the Chocolate Mousse

  • In a saucepan, heat heavy cream until warm. Pour over semi-sweet chocolate chips and let sit for two minutes.
  • Stir until smooth and let cool to room temperature.
  • In a separate bowl, whip remaining heavy cream and powdered sugar until stiff peaks form.
  • Gently fold whipped cream into the melted chocolate mixture.

Assemble the Cake

  • Place one cooled cake layer onto your serving plate.
  • Spread chocolate mousse evenly over the top of the cake layer.
  • Carefully place the second cake layer on top and refrigerate for 30 minutes.

Make the Ganache & Decorate

  • Heat heavy cream until warm and pour over chocolate chips and butter.
  • Stir until you achieve a glossy ganache.
  • Pour ganache over the chilled cake, allowing it to cascade down the sides.
  • Garnish with fresh strawberries, chocolate shavings, and curls.

Chill & Serve

  • Refrigerate the decorated cake for at least 1 hour before slicing.
  • Slice through the layers and serve to your family or guests.

Notes

Ensure to use room temperature ingredients for better mixing. Chill between layers for perfect mousse texture. Avoid overmixing to maintain fluffiness.
