Ingredients:

For the Chocolate Sponge Cake:

1 cup all-purpose flour
1/2 cup unsweetened cocoa powder
1 teaspoon baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
3 large eggs, at room temperature
1 cup granulated sugar
1/2 cup vegetable oil
1 teaspoon vanilla extract
1/2 cup buttermilk, at room temperature

For the Chocolate Mousse:

8 ounces semi-sweet chocolate, chopped
2 cups heavy cream, divided
1 teaspoon vanilla extract
Pinch of salt
1/4 cup powdered sugar

For the Chocolate Ganache (Optional):

4 ounces semi-sweet chocolate, chopped
1/2 cup heavy cream


Instructions:

Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, or line them with parchment paper for easy removal. Set aside.


In a medium bowl, sift together the all-purpose flour, cocoa powder, baking powder, baking soda, and salt. Set aside.


In a large mixing bowl, beat the eggs and granulated sugar together until pale and fluffy, about 2-3 minutes.


Slowly add the vegetable oil and vanilla extract to the egg mixture, beating until well combined.


Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk, beginning and ending with the dry ingredients. Mix until just combined, being careful not to overmix.


Divide the batter evenly between the prepared cake pans and smooth the tops with a spatula.


Bake the cakes in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean.


Remove the cakes from the oven and allow them to cool in the pans for 10 minutes before transferring them to wire racks to cool completely.


While the cakes are cooling, prepare the chocolate mousse. Place the chopped semi-sweet chocolate in a heatproof bowl.


In a small saucepan, heat 1 cup of heavy cream over medium heat until it just begins to simmer. Pour the hot cream over the chopped chocolate and let it sit for 1-2 minutes.


Gently stir the chocolate and cream together until the chocolate is completely melted and the mixture is smooth. Stir in the vanilla extract and a pinch of salt. Let the mixture cool to room temperature.


In a separate mixing bowl, beat the remaining 1 cup of heavy cream and powdered sugar together until stiff peaks form.


Gently fold the whipped cream into the cooled chocolate mixture until well combined and no streaks remain.


To assemble the cake, place one layer of chocolate sponge cake on a serving plate or cake stand. Spread a layer of chocolate mousse evenly over the top.


Carefully place the second layer of chocolate sponge cake on top of the mousse layer. Cover the top and sides of the cake with the remaining chocolate mousse, using an offset spatula to create smooth, even layers.


Refrigerate the cake for at least 4 hours, or until the mousse is set.


Optional: Prepare the chocolate ganache by placing the chopped semi-sweet chocolate in a heatproof bowl. In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer. Pour the hot cream over the chopped chocolate and let it sit for 1-2 minutes. Gently stir the chocolate and cream together until smooth. Let the ganache cool slightly, then pour it over the chilled cake, allowing it to drip down the sides.


Slice and serve the Chocolate Mousse Cake, savoring each decadent bite of rich chocolate goodness.


Store any leftovers in the refrigerator for up to 3 days.
