Step‑by‑Step Instructions for Chocolate Mousse Cake
  1. Preheat the oven to 350°F (175°C) and grease two 9-inch round cake pans.
  2. In a large mixing bowl, sift together flour, sugar, cocoa powder, baking soda, baking powder, and salt.
  3. In a separate bowl, whisk together the vegetable oil, buttermilk, eggs, and vanilla extract. Fold into the dry ingredients.
  4. Slowly add boiling water to the batter while stirring continuously until smooth.
  5. Divide the batter between the prepared pans and bake for 25–30 minutes until a toothpick comes out clean.
  6. Cool the cakes for about 10 minutes, then invert onto a wire rack to cool completely.
  7. For the mousse, heat heavy cream until steaming, pour over chopped chocolate, and whisk until smooth. Fold in whipped cream.
  8. For the ganache, heat more heavy cream until simmering, pour over chocolate, and stir until smooth.
  9. Assemble by layering cake and mousse, then cover with remaining mousse. Pour ganache over the top.
  10. Chill the assembled cake in the refrigerator for at least 2 hours before serving.
