Most Amazing Chocolate Mousse Cake

Instructions for Making the Most Amazing Chocolate Mousse Cake

1. Prepare the Cake Layer

Start by preheating your oven to 350°F (175°C). Grease and line a 9-inch round cake pan with parchment paper.

In a large mixing bowl, sift together the flour, cocoa powder, baking powder, baking soda, and salt. This will ensure your dry ingredients are well-mixed and your cake will be light and fluffy.

In a separate bowl, cream together the unsalted butter and sugar until light and fluffy, about 3-4 minutes. Add the eggs, one at a time, beating well after each addition. Stir in the vanilla extract.

Now, alternately add the dry ingredients and milk to the butter mixture, starting and ending with the dry ingredients. Mix until just combined. The batter will be somewhat thick. Finally, pour in the boiling water and mix until smooth. The water will loosen the batter, making it silky and easy to pour.

Pour the batter into the prepared cake pan and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Let the cake cool completely in the pan before transferring it to a wire rack.

2. Make the Chocolate Mousse

While the cake is cooling, prepare the chocolate mousse. Start by melting the semisweet or bittersweet chocolate in a heatproof bowl over a pot of simmering water (double boiler method) or by microwaving it in 20-second bursts, stirring between each interval until smooth.

Once the chocolate is melted, allow it to cool to room temperature. Meanwhile, whip the heavy cream with the sugar and vanilla extract in a chilled bowl until soft peaks form.

Once the chocolate has cooled, fold it into the whipped cream gently until fully combined. Be careful not to deflate the whipped cream; you want to maintain the mousse’s light, airy texture. Once mixed, refrigerate the mousse to firm up for about 30 minutes.

3. Assemble the Cake

Once the cake has completely cooled, cut it in half horizontally to create two layers. Place the bottom layer on a serving plate or cake stand. Spread the chocolate mousse evenly over the cake layer, smoothing it out with a spatula.

Top with the second cake layer and press gently to set. Refrigerate the assembled cake for at least 1 hour to allow the mousse to set properly and ensure it holds its shape when sliced.

4. Make the Chocolate Ganache

To make the ganache, heat the heavy cream in a small saucepan over medium heat until it just begins to simmer. Remove from the heat and pour it over the chopped semisweet or bittersweet chocolate in a heatproof bowl. Let it sit for a minute, then stir until the chocolate is completely melted and smooth.

Allow the ganache to cool for about 10-15 minutes, until it thickens slightly but is still pourable. Pour the ganache over the top of the assembled cake, letting it drip down the sides. Use a spatula to smooth it out if necessary.

5. Garnish and Serve

For an extra touch of elegance, garnish your cake with chocolate shavings, chocolate curls, or fresh berries. Refrigerate the cake for another 30 minutes to set the ganache before slicing.
