Instructions

Chocolate Cake:

  1. Preheat your oven to 350°F (175°C). Grease and flour two 8 or 9-inch round baking pans, and optionally line the bottom with wax or parchment paper.
  2. In a large bowl, combine sugar, flour, cocoa powder, baking powder, baking soda, and salt.
  3. Add eggs, buttermilk, oil, and vanilla to the dry ingredients.
  4. Beat everything together on medium speed for around two minutes until it’s well mixed
  5. Stir in boiling water; the batter will be thin. Pour the batter into the prepared pans.
  6. Bake for around 30-32 minutes or until a toothpick inserted in the center comes out clean.
  7. Let the cakes cool in the pans for 5 minutes, then transfer them to wire cooling racks to cool completely. You can also freeze the cake rounds at this point if desired.

Chocolate Mousse:

  1. Stir cocoa powder and hot water together.
  2. Melt chocolate chips in a double-boiler or microwave until smooth.
  3. Add the cocoa mixture to the melted chocolate chips and mix well. Let it cool to room temperature.
  4. In a bowl, beat cream and sugar until stiff peaks form.
  5. Gently fold in the chocolate mixture until well combined.
  6. Refrigerate until ready to use, up to FIVE days.

Chocolate Frosting:

  1. In a medium saucepan, combine milk, cocoa, and butter. Bring to a boil, then remove from heat.
  2. Add powdered sugar and mix with electric beaters until smooth and free of lumps.
  3. Allow the frosting to cool for 15-20 minutes, stirring occasionally.

Assembly:

  1. Once the cakes have cooled, use a sharp serrated knife to cut each cake evenly in half horizontally, resulting in four thin 9-inch cake pieces.
  2. Place the first cake layer on a cake serving plate and spread a generous spoonful of mousse on top.
  3. Repeat this process with the remaining cake layers, adding a layer of mousse filling between each layer of cake.
  4. Use the remaining mousse filling to spread it evenly around the entire outside and top of the cake. Refrigerate for 30 minutes.
  5. While the cake chills, prepare the warm chocolate frosting.
  6. Remove the cake from the fridge and slowly pour the cooled chocolate frosting over the top. Use a spatula or knife to gently spread the frosting evenly over the outside of the cake as you pour.
  7. Refrigerate the cake until ready to serve.
  8. Enjoy your delicious layered chocolate mousse cake!
