Timing
Making Chocolate Caramel Mousse Cake takes about 30 minutes for preparation, 30 minutes for baking, and at least 4 hours for chilling.
Instructions
Step 1: Prepare the Chocolate Cake
- Preheat Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan.
- Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
- Combine Wet Ingredients: Add the softened butter, eggs, vanilla extract, and buttermilk to the dry ingredients. Mix until well combined.
- Add Boiling Water: Carefully stir in the boiling water until the batter is smooth (the batter will be thin).
- Bake: 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 cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
Step 2: Prepare the Caramel Mousse
- Dissolve Gelatin: In a small bowl, sprinkle the gelatin over the water and let it sit for about 5 minutes to bloom. Then, heat gently until dissolved (do not boil).
- Whip Cream: In a separate bowl, whip the chilled heavy cream until stiff peaks form.
- Combine: In another bowl, mix the caramel sauce with the dissolved gelatin and vanilla extract until smooth. Gently fold in the whipped cream until fully combined.
Step 3: Assemble the Cake
- Layer Cake: Once the chocolate cake has cooled, slice it in half horizontally to create two layers.
- Add Mousse: Place one layer of cake on a serving plate. Spread half of the caramel mousse over the top. Place the second layer of cake on top and spread the remaining mousse over the top and sides of the cake. Smooth it out with a spatula.
- Chill: Refrigerate the cake for at least 4 hours or until the mousse is set (overnight is best).
Step 4: Prepare the Chocolate Ganache
- Heat Cream: In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer.
- Add Chocolate: Remove from heat and add the chocolate chips. Let sit for a minute, then stir until smooth and glossy.
Step 5: Finish the Cake
- Pour Ganache: Once the mousse is set, pour the chocolate ganache over the top of the cake, allowing it to drip down the sides.
- Garnish: Drizzle with additional caramel sauce and sprinkle chocolate shavings on top for decoration.
Step 6: Serve
- Slice and Enjoy: Slice the cake and serve chilled. Enjoy your delicious Chocolate Caramel Mousse Cake!
