Cake Ingredients

Method

Cake Preparation

  1. 1

    Preheat Oven

    Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.

  2. 2

    Mix Dry Ingredients

    In a large mixing bowl, sift together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.

  3. 3

    Combine Wet Ingredients

    In another bowl, whisk together the eggs, milk, vegetable oil, and vanilla extract until well combined.

  4. 4

    Combine Mixtures

    Gradually add the wet ingredients to the dry ingredients, mixing until just combined.

  5. 5

    Add Boiling Water

    Carefully stir in the boiling water. The batter will be very thin, but that's okay.

  6. 6

    Bake Cake

    Divide the batter evenly between the prepared cake pans. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.

  7. 7

    Cool Cakes

    Remove from the oven and allow the cakes to cool in the pans for 10 minutes, then transfer them to wire racks to cool completely.

Mousse Preparation

  1. 8

    Melt Chocolate

    In a microwave-safe bowl, melt the semisweet chocolate in 30-second increments, stirring until smooth. Allow to cool slightly.

  2. 9

    Dissolve Gelatin

    In a small bowl, sprinkle the gelatin powder over the 2 tablespoons of water and let it sit for about 5 minutes to bloom. Then, heat gently until dissolved.

  3. 10

    Combine Chocolate and Gelatin

    Stir the dissolved gelatin into the melted chocolate until fully combined.

  4. 11

    Whip Cream

    In a separate bowl, whip the heavy cream with the powdered sugar and vanilla extract until soft peaks form.

  5. 12

    Fold Mousse

    Gently fold the whipped cream into the chocolate mixture until no streaks remain. Be careful not to deflate the whipped cream.

  6. 13

    Chill Mousse

    Refrigerate the mousse for at least 30 minutes until it thickens slightly.

Assemble Cake

  1. 14

    Layer Cakes

    Once the cakes are completely cooled, place one layer on a serving plate. Spread a generous amount of mousse on top.

  2. 15

    Add Second Layer

    Place the second cake layer on top of the mousse-covered layer and press down gently.

  3. 16

    Top with Mousse

    Spread the remaining mousse over the top and sides of the cake.

  4. 17

    Chill the Cake

    Cover the cake with plastic wrap and refrigerate for at least 2 hours before serving.

  5. 18

    Serve

    Slice the cake and serve chilled. Enjoy your delicious Chocolate Mousse Cake!
