Method
 

Step‑by‑Step Instructions
  1. Preheat your oven to 350°F (175°C) and prepare two 9-inch round cake pans by greasing them with butter or cooking spray and dusting with flour.
  2. In a large mixing bowl, whisk together the dry ingredients: flour, sugar, cocoa, baking powder, baking soda, and salt until well combined.
  3. In another bowl, beat together the wet ingredients: eggs, vegetable oil, buttermilk, and hot coffee until smooth and uniform.
  4. Gently fold the wet ingredients into the dry ingredients until just combined without over-mixing.
  5. Divide the batter evenly between the prepared cake pans and bake for 25–30 minutes or until a toothpick comes out clean.
  6. While the cakes cool, melt the semisweet chocolate and whip the heavy cream with powdered sugar and vanilla until stiff peaks form.
  7. Fold melted chocolate into the whipped cream to create the mousse, then assemble the cake layers with mousse in between and on top.
  8. For the ganache, heat the cream and pour it over the chopped chocolate with corn syrup and butter; stir until smooth.
  9. Pour the ganache over the assembled cake, slice with a hot knife, and serve chilled.
